  • Pest Control in a Home With Babies and Toddlers: A Room-by-Room Plan

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Babies and toddlers crawl on floors, put everything in their mouths and weigh very little. All of that makes them more exposed to whatever lands on floors and surfaces. That doesn’t mean you have to live with bugs. It means choosing targeted methods and putting every product out of reach.

    The guiding principle: Prevent first, then use the most targeted product that works (enclosed baits, larvicides, crack-and-crevice treatments) instead of sprays across open floors. Store every product locked up, in its original container. Keep the Poison Help line handy: 1-800-222-1222.

    Prevention that cuts most problems

    • Seal entry points: door sweeps, window screens and caulk around pipes.
    • Keep food contained: snack crumbs under high chairs and car seats are the classic ant magnet.
    • Fix moisture: leaks attract roaches, silverfish and more.
    • Vacuum often, especially where kids eat and play.

    Room by room

    Kitchen

    Ants and roaches are the main problems. Use enclosed bait stations placed behind appliances or inside cabinets with child locks, not on open floors. Clean up crumbs before bed. See our ant guide and roach guide.

    Living areas and nursery

    Avoid spraying floors, rugs and play mats. If fleas come in with a pet, treat the pet with a vet-recommended product and vacuum daily rather than spraying the whole room. If you do use a home spray, keep children out until it’s completely dry and follow the label’s re-entry directions. Never use foggers.

    Bathroom and laundry

    Silverfish and roaches love damp spaces. Run the exhaust fan, fix drips, and put any dust treatment only inside wall voids or behind panels, never on open surfaces.

    Yard and play areas

    For mosquitoes, empty standing water weekly (toys, kiddie pools, buckets) and use Bti dunks in water you can’t empty. Skip broadcast yard sprays near sandboxes and play sets. See our mosquito guide. For bug repellent on kids, use an EPA-registered product and follow age limits on the label. Oil of lemon eucalyptus, for example, isn’t for children under 3.

    Check price for Mosquito Dunks →

    Storage rules

    • Lock pesticides up, high and out of sight.
    • Keep them in their original labeled containers. Never pour them into drink bottles.
    • Close child-resistant caps fully, every time.
    • Remove kids, toys and pacifiers from an area before treating it.

    If you hire a pest control company

    Ask for an integrated pest management (IPM) approach: inspection, sealing, baiting and targeted crack-and-crevice treatment rather than routine spraying. Ask which products they’ll use, what the re-entry time is, and tell them you have an infant.

    If a child swallows or touches a pesticide, call Poison Help at 1-800-222-1222, or 911 if the child is having trouble breathing, is unconscious or is having a seizure. Always follow product labels.

  • Lower-Toxicity Bed Bug Treatment: What Works and When to Call a Pro

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Bed bugs are one of the hardest household pests to eliminate, and many populations resist common insecticides. The good news is that some of the most effective tools aren’t chemical at all: heat, laundering, vacuuming and physical barriers. The honest news: established infestations usually need a professional.

    Quick answer: Confirm it’s bed bugs, run bedding and clothes through a hot dryer, vacuum thoroughly, put the mattress and box spring in bed bug encasements, put interceptors under the bed legs, and call a pro if you see bugs after two to three weeks. Never use outdoor or agricultural pesticides indoors.

    Step 1: Confirm what you have

    Look along mattress seams, the box spring, headboard and bed frame for live bugs (apple-seed sized, reddish-brown), shed skins, tiny white eggs, and dark spotting. Bites alone don’t confirm bed bugs. If you can, catch a specimen in tape or a sealed bag so you or your local extension office can identify it.

    Step 2: Heat what you can

    Bed bugs and their eggs die with enough heat. Put bedding, clothing, curtains and stuffed toys in a clothes dryer on high heat for at least 30 minutes, after washing if they’re dirty. Bag items in sealed plastic to carry them to the laundry so you don’t spread bugs on the way.

    Check price for dissolvable laundry bags →

    Step 3: Vacuum and declutter

    Vacuum mattress seams, bed frames, baseboards, carpet edges and furniture. Seal the vacuum bag in plastic and throw it away outside. Reduce clutter around the bed, since every pile is a new hiding place.

    Step 4: Encase the mattress and box spring

    A zippered encasement made for bed bugs traps any bugs inside (where they eventually die) and leaves a smooth surface that’s easy to inspect. Keep it on for at least a year.

    Check price for bed bug mattress encasements →

    Step 5: Isolate the bed with interceptors

    Interceptor cups go under each bed leg and catch bugs trying to climb up, which also helps you monitor progress. Pull the bed a few inches from the wall and keep bedding from touching the floor.

    Check price for bed bug interceptors →

    What about diatomaceous earth?

    Desiccant dusts can be part of a bed bug plan, but the EPA advises using one that is registered by the EPA and labeled for bed bug control. Food-grade and pool-grade DE aren’t intended for that use, and they pose more of an inhalation risk. Apply registered dusts sparingly in cracks, voids and behind outlet covers, not across beds and floors.

    Check price for EPA-registered bed bug dust →

    What NOT to do

    • Don’t use foggers (“bug bombs”). They don’t reach bed bugs in cracks and can spread them.
    • Don’t use outdoor, garden or agricultural pesticides indoors. This causes real poisonings.
    • Don’t use rubbing alcohol or other flammable liquids on furniture; fires have resulted.
    • Don’t sleep on the couch. The bugs will follow you and spread.

    When to call a pro

    If you’re still finding live bugs after two to three weeks, or the infestation is in several rooms or a multi-unit building, call a licensed pest professional. Ask about whole-room heat treatment, which can kill all life stages in one visit with no chemical residue, and about IPM-based follow-up inspections.

    Always read and follow product labels. In rental housing, notify your landlord. Many states and cities have bed bug disclosure and treatment rules.

  • Natural Roach Control: Boric Acid, Baits and Sealing Them Out

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Cockroaches are hardy, but they have simple needs: food, water and tight hiding places. Take those away and add a slow-acting bait or dust where they hide, and you can knock down most home infestations without fogging your house.

    Quick answer: Clean up food and moisture, seal cracks, place roach bait stations near hiding spots, and lightly dust boric acid inside wall voids and gaps where kids and pets can’t reach. Skip foggers, which scatter roaches and leave residue everywhere.

    Step 1: Cut off food and water

    • Wipe counters and stovetops nightly. Degrease behind and beside the stove.
    • Store food, including pet food, in sealed containers.
    • Take trash out nightly and use a lidded can.
    • Fix dripping faucets and leaky pipes under sinks. Roaches can live longer without food than without water.
    • Don’t leave pet water out overnight in heavy infestations.

    Step 2: Seal hiding spots

    German cockroaches, the common indoor species, hide in warm, tight cracks near the kitchen and bathroom. Caulk gaps around backsplashes, cabinet edges, baseboards and pipe penetrations. Use foam or steel wool around larger plumbing openings.

    Check price for kitchen and bath caulk →

    Step 3: Use boric acid the right way

    Boric acid is a low-cost, long-lasting roach dust. Roaches walk through it and ingest it when grooming. The mistake most people make is using too much. Roaches avoid visible piles.

    1. Use a product labeled as an insecticide for roaches, and follow the label.
    2. Apply with a bulb duster or the bottle’s applicator tip to puff a barely visible film.
    3. Target hidden places: under and behind the fridge and stove, under the sink, inside cabinet hinge gaps, in wall voids behind outlet covers (power off) and along the back edges of cabinets.
    4. Keep it out of open areas, food-prep surfaces and anywhere kids or pets can reach.
    5. Give it one to two weeks.

    Check price for boric acid roach powder →

    Step 4: Add bait stations

    Enclosed roach bait stations put a small amount of insecticide in a food attractant inside a child-resistant housing. Place several near hiding spots, such as corners under the sink and behind appliances, and don’t spray cleaners on or around them. Some baits use borates; others use conventional actives. Read the label to see what you’re getting.

    Check price for roach bait stations →

    Monitor with sticky traps

    Glue traps don’t solve an infestation, but they show where roaches are concentrated and whether numbers are dropping. Put them flat against walls and in corners, and check them weekly.

    Check price for roach sticky traps →

    When to call a professional

    If you still see roaches in daylight after four to six weeks of steady effort, or if you live in a multi-unit building where roaches move between apartments, a professional using integrated pest management (IPM) is usually worth it. Ask companies whether they offer gel baits, inspections and sealing rather than routine spraying.

    Always read and follow the product label. Store pesticides in their original containers, out of reach of children and pets.

  • What “Minimum Risk” Pesticides Are and How to Read a Bug Spray Label

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    If you’re trying to choose a gentler insecticide, the label is your best tool, but only if you know how to read it. This guide explains the federal “minimum risk” category, what an EPA registration number means, and why no legitimate pesticide label will ever tell you a product is “safe.”

    Two kinds of products on the shelf

    1. EPA-registered pesticides

    Most insecticides, including many natural ones like spinosad, Bt and borax baits, are registered with the U.S. Environmental Protection Agency. You’ll see an “EPA Reg. No.” on the label. Registration means the EPA reviewed data on the product’s effects and approved the label directions.

    2. “Minimum risk” (FIFRA 25(b)) products

    Under section 25(b) of the federal pesticide law (FIFRA), certain products are exempt from EPA registration if they contain only active ingredients from an EPA list, such as cedar oil, cinnamon oil, citric acid, clove oil, peppermint oil, garlic, rosemary oil and others, and only approved inert ingredients, and meet labeling conditions. In November 2022 the EPA added chitosan to the list.

    Key things to know about 25(b) products:

    • The EPA does not review them for effectiveness. Results vary widely.
    • Most states still require registration before they’re sold.
    • They must list all ingredients, active and inert, on the label.
    • “Minimum risk” refers to the ingredient list, not a promise that a product is harmless. Many 25(b) oils are hazardous to cats, for example (see our cat guide).

    Why you won’t see “safe” on a real label

    Federal rules (40 CFR 156.10) treat safety claims such as “safe,” “nonpoisonous,” “harmless” or “nontoxic to humans and pets” as false or misleading on pesticide labeling, even with “when used as directed” attached. If a bug product’s label or ads promise it’s “100% safe,” treat that as a red flag.

    How to read a label, section by section

    1. Active ingredient(s) and percentage. This tells you what actually does the work. Look it up on the National Pesticide Information Center (npic.orst.edu), which has plain-language fact sheets.
    2. Signal word. “Caution” is the lowest toxicity category, then “Warning,” then “Danger.” Many lower-toxicity products carry “Caution” or no signal word.
    3. Precautionary statements. Hazards to people, pets, fish, bees and other wildlife. Read these first if you have pets or a pond.
    4. Directions for use. Which pests, which sites (indoor, outdoor, food plants), how much and how often. “The label is the law”: using a product contrary to its label is illegal.
    5. Re-entry and pre-harvest intervals. How long to stay out of treated areas and wait before harvesting food.
    6. Storage and disposal. Never pour leftovers down a drain.

    A simple way to compare products

    • Pick the product whose label lists your specific pest and site.
    • Prefer targeted products such as baits, larvicides and spot treatments over broadcast sprays.
    • Check precautions against your household: cats, fish tanks, bees in the garden, small kids.
    • Use the smallest amount that works, and combine it with non-chemical steps like sealing, cleaning and removing water.

  • Are Essential Oil Bug Sprays Safe for Cats? What Vets Say

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    “Natural” bug sprays made with essential oils are often marketed as the gentle choice for families with pets. For dogs and people that’s often reasonable. Cats are a different story. Veterinary organizations warn that many essential oils can poison cats, and pest control products are a common source of exposure.

    Bottom line: Don’t use essential-oil insect products on or around cats unless the product is specifically labeled for cats and your veterinarian has okayed it. If you suspect a reaction, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435.

    Why cats are different

    Cats’ livers process certain compounds, including many found in essential oils, much less efficiently than dogs’ or people’s do, so those compounds can build up to toxic levels. Cats are also small, groom constantly, and lie on floors and furniture, so residue on fur, paws and fabric ends up in their mouths. PetMD notes that some essential-oil flea products labeled for cats can still cause poisoning even when used as directed.

    Oils commonly flagged as toxic to cats

    Lists vary slightly between sources, but veterinary groups including the PDSA, Cats Protection, Hill’s and PetMD repeatedly name:

    • Tea tree (melaleuca), which is especially dangerous
    • Peppermint and other mints
    • Citrus oils (lemon, orange, lime, d-limonene)
    • Clove and cinnamon
    • Eucalyptus
    • Lavender
    • Pine
    • Pennyroyal, wintergreen and sweet birch
    • Ylang ylang, thyme and oregano

    Many of these are exactly the ingredients in “natural” flea sprays, ant sprays and spider repellents.

    Warning signs

    • Drooling or pawing at the mouth
    • Vomiting
    • Wobbliness, weakness or tremors
    • Trouble breathing, coughing or panting
    • Redness or burns on the skin, lips or tongue

    If you see these after an exposure, don’t wait. Wash any product off the fur with a mild dish soap if you can do it without stressing the cat, and call your vet.

    Lower-risk bug control in a cat home

    • Fleas: Use a vet-recommended flea product made for cats, and vacuum daily. Don’t use dog flea products on cats; many contain permethrin, which is highly toxic to cats.
    • Ants: Enclosed borax bait stations placed where your cat can’t get to them, plus cleanup and sealing. See our ant guide.
    • Roaches: Enclosed bait stations and sealing gaps, or boric acid dusted only inside wall voids and cracks the cat can’t reach. See our roach guide.
    • Flying insects: Window screens, fans and sticky or light traps placed out of reach.

    Check price for indoor plug-in insect traps →

    What about diffusers and cleaners?

    The same concern applies to essential oils in diffusers, candles and DIY cleaning sprays, especially in small, closed rooms. If you use them, keep them out of rooms your cat uses and never let your cat be stuck with no way out.

    This article is general information, not veterinary advice. Talk to your veterinarian about your cat’s specific health and any products you plan to use.

  • Organic Garden Pest Control: Insecticidal Soap, Neem, Spinosad and Bt Compared

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Garden centers have a whole aisle of “organic” insect killers, and they are not interchangeable. Each works on different pests in different ways. Use the wrong one and you’ll waste money, and possibly harm the bees and ladybugs that are on your side. Here’s how to match the product to the problem.

    Quick answer: Soft-bodied pests like aphids and mites call for insecticidal soap. Caterpillars call for Bt (kurstaki). Tougher chewers and thrips call for spinosad. For mixed pests and some fungal problems, try neem oil. Spray in the evening and never on open blooms bees are visiting.

    At a glance

    Product type Best for How it works Watch out for
    Insecticidal soap Aphids, whiteflies, mealybugs, spider mites Breaks down the insect’s outer coating; contact only Must hit the pest directly; can burn sensitive or hairy-leaved plants; avoid heat over 90°F
    Bt kurstaki Caterpillars (hornworms, cabbage worms, loopers) Bacterial toxin caterpillars eat Also kills butterfly caterpillars you want; washes off in rain
    Spinosad Caterpillars, thrips, leaf miners, some beetles, spider mites Affects insect nervous system; contact and ingestion Toxic to bees while wet; spray at dusk, off flowers
    Neem oil Mixed soft-bodied pests; some fungal issues Smothers and disrupts feeding and growth Can burn plants in heat or sun; avoid blooms

    Insecticidal soap

    True insecticidal soap is not dish soap. Products like Safer Brand Insect Killing Soap use potassium salts of fatty acids, which weaken the protective outer layer of soft-bodied insects so they dehydrate. It works only on contact, so coat the undersides of leaves where aphids cluster, and repeat every 5 to 7 days while pests are present. The National Pesticide Information Center notes it breaks down quickly in soil. Test on a few leaves first, since some plants are sensitive.

    Check price for Safer Brand Insect Killing Soap →

    Bt (Bacillus thuringiensis var. kurstaki)

    Bt kurstaki is a bacterium that kills caterpillars after they eat treated leaves. It doesn’t harm bees, ladybugs or people at labeled rates. It will kill any caterpillar, though, including monarchs and swallowtails, so only spray plants that are actually under attack. Reapply after rain.

    Check price for Bt caterpillar killer →

    Spinosad

    Spinosad comes from a soil bacterium and is widely used in organic farming. Bonide Captain Jack’s Deadbug Brew is the best-known garden version. Its label lists caterpillars, bagworms, leaf miners, thrips, spider mites and certain beetles. Spinosad-treated insects may stop feeding quickly but take a day or two to die, so check results after 2 or 3 days before respraying. It’s toxic to bees while wet: spray in the evening, keep it off open flowers, and let it dry.

    Check price for Captain Jack's Deadbug Brew →

    Neem oil

    Neem oil, pressed from neem tree seeds, works as a smothering oil and feeding disruptor against many soft-bodied pests, and some formulations also help with powdery mildew. Apply in the evening, never in full sun or high heat, and keep it off flowers.

    Check price for neem oil spray →

    Before you spray anything

    • Identify the pest. Your local Cooperative Extension office can help, often for free.
    • Try a hard spray of water first for aphids. It knocks many off for good.
    • Hand-pick big pests like hornworms and beetles.
    • Encourage predators such as ladybugs, lacewings and parasitic wasps by planting flowers like dill, yarrow and alyssum.
    • Check the label for which crops it’s approved on and how long to wait before harvest.

    Always read and follow label directions, including pre-harvest intervals. “Organic” and “OMRI Listed” do not mean a product has no effect on people, pets or beneficial insects.

  • Mosquito Control Without Spraying Your Whole Yard

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Broadcast yard sprays kill whatever they touch, including bees, butterflies and the insects that eat mosquitoes. A more targeted plan attacks mosquitoes where they breed: standing water. Most backyard mosquitoes never travel far from where they hatched, so cleaning up your own yard makes a real difference.

    Quick answer: Dump standing water weekly. Treat water you can’t dump with Bti “mosquito dunks.” Use a fan on the patio, and use an EPA-registered personal repellent when you’re outside at dawn and dusk.

    Step 1: The weekly water walk

    Mosquitoes can go from egg to adult in about a week in warm weather, so a weekly check breaks the cycle. Walk your property and tip out:

    • Flowerpot saucers, buckets, wheelbarrows and toys
    • Tarps and pool covers that hold puddles
    • Old tires and gutters that don’t drain
    • Pet water bowls outdoors (refill fresh daily)
    • Bird baths (scrub and refill weekly)

    Step 2: Treat water you can’t dump with Bti

    For rain barrels, ponds, water gardens, drainage areas and troughs, use Bti (Bacillus thuringiensis subspecies israelensis). It’s a naturally occurring bacterium that is toxic to the larvae of mosquitoes and a few related flies when they eat it.

    Summit Mosquito Dunks

    The best-known Bti product. According to the manufacturer, each donut-shaped dunk treats up to 100 square feet of water surface for about 30 days, and the product is labeled for use in fish habitats and animal watering troughs. Break a dunk into pieces for smaller containers and replace it monthly during mosquito season.

    Check price for Mosquito Dunks →

    Mosquito Bits

    The granular version of Bti from the same maker is handy for scattering into gutters, plant saucers and wet low spots.

    Check price for Mosquito Bits →

    Step 3: Make your patio less appealing

    • Run a fan. Mosquitoes are weak fliers, so even a moderate breeze on a deck keeps many away.
    • Trim dense shrubs near seating areas, where adults rest during the day.
    • Swap porch bulbs for yellow “bug lights.” They don’t repel mosquitoes, but they draw fewer other insects.

    Check price for outdoor patio fans →

    Step 4: Protect people

    For your skin, use a repellent registered with the EPA. The EPA has an online search tool to compare options and protection times. Ingredients include picaridin, IR3535, oil of lemon eucalyptus (not for children under 3) and DEET. Follow the label, especially for children.

    What about plant-oil yard sprays?

    Cedar and other essential-oil yard sprays are sold as lower-impact alternatives. They tend to be short-lived and need frequent reapplication, and they can still affect beneficial insects on contact. If you use one, spot-treat shady resting areas rather than flowers, apply in the evening when bees are less active, and keep cats away from treated areas until dry.

    Always read and follow pesticide label directions. Check local health department guidance in areas with mosquito-borne disease activity.

  • Diatomaceous Earth for Bugs: Food Grade vs. Pool Grade and How to Use It

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Diatomaceous earth (DE) is one of the most popular non-chemical bug killers. It’s a fine powder made from the fossilized shells of tiny algae called diatoms. It works mechanically rather than chemically, but “natural” doesn’t mean “use it carelessly.” Here’s how to buy the right kind and use it well.

    Quick answer: Buy food-grade DE (or an EPA-registered DE insecticide), apply a thin layer only in dry areas, wear a dust mask while applying, and keep kids and pets out until the dust settles. Never use pool or filter grade for pests.

    How DE kills insects

    Under a microscope, DE particles are sharp and highly absorbent. When an insect crawls through it, the powder damages and strips the waxy outer coating that keeps the insect from drying out, and the insect dehydrates over hours to days. Because it’s a physical action, insects don’t develop resistance to it the way they can to chemical insecticides.

    Food grade vs. pool grade: the critical difference

    Food grade Pool / filter grade
    Processing Not heat-treated Heat-treated (calcined)
    Crystalline silica Typically under 1% High (often well over half)
    Use for pests? Yes, carefully Never

    Calcining turns much of the silica into its crystalline form, which can cause serious lung disease when inhaled. Pool-grade DE belongs only in a pool filter. The color won’t tell you which is which; the label will.

    Check price for food-grade diatomaceous earth →

    Check price for a bulb duster applicator →

    What DE works on

    • Ants, along travel paths and in wall voids
    • Cockroaches, behind and under appliances
    • Fleas, worked lightly into carpet, then vacuumed after a few days
    • Silverfish, earwigs and crickets
    • Garden pests like slugs, when dry. It can also harm beneficial insects, so don’t dust flowers bees visit.

    A note on bed bugs: the EPA advises that if you use a desiccant dust for bed bugs, it should be one registered by the EPA and labeled for bed bug control. Food-grade and pool-grade products aren’t intended for that use. See our bed bug guide.

    How to apply DE the right way

    1. Wear a dust mask and keep kids and pets out of the room.
    2. Use a bulb duster to puff a barely visible film. Insects walk around thick piles but straight through thin dust.
    3. Target hidden, dry spots: cracks, baseboard gaps, behind the fridge and stove, under sinks, wall voids and outlets (with the cover off and power off).
    4. Let it work for several days. DE is slower than sprays.
    5. Clean up visible dust from open floors with a vacuum (a shop vac with a fine filter is best), and reapply in hidden areas as needed.
    6. Reapply outdoors after rain or watering. DE stops working when wet.

    Common mistakes

    • Dumping thick piles on the floor
    • Applying it in damp areas like under a leaky sink, where it clumps and stops working
    • Puffing it into the air in an occupied room
    • Buying pool grade because it was cheaper

    Follow product label directions. Products sold specifically to kill insects must carry pesticide labeling; follow it.

  • How to Get Rid of Ants Without Harsh Chemicals

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Spraying the ants you can see feels satisfying, but it rarely solves the problem. The workers you kill are a small part of the colony, and the queen keeps laying. The most effective lower-toxicity approach is to let the ants carry a slow-acting bait back to the nest, while you remove whatever drew them in.

    Quick answer: Clean up food and sugar sources, place a borax-based liquid bait along the trail, don’t spray the trail, and give it one to two weeks. Seal entry points once activity drops.

    Step 1: Figure out what they’re after

    Most kitchen ants are “sweet-eating” ants such as odorous house ants, pavement ants and Argentine ants. Follow the trail and you’ll usually find spilled juice, a pet food bowl, a sticky syrup bottle, or crumbs under the toaster. Wipe surfaces with soapy water or a vinegar solution. That removes both the food and the scent trail ants use to navigate.

    Step 2: Use a slow bait, not a spray

    Liquid ant baits mix a sweet attractant with a low dose of an insecticide, so workers survive long enough to share it with the colony. The best-known example is TERRO Liquid Ant Baits, whose active ingredient is borax (sodium tetraborate decahydrate, 5.4%). According to the manufacturer, the baits target common sweet-eating household ants but not fire ants, pharaoh ants, carpenter ants or harvester ants.

    Check price for TERRO Liquid Ant Baits →

    How to use bait well

    • Put stations right on or beside the trail, plus near the entry point.
    • Expect more ants for the first day or two. That means it’s working.
    • Don’t spray cleaners or insecticides near the bait; it breaks the trail.
    • Replace stations when they’re empty. Full control can take up to two weeks.
    • Place baits where children and pets can’t reach them, as the label directs.

    Step 3: Seal and block

    Once activity slows, close the doors: caulk gaps around window frames, baseboards, plumbing penetrations and the spot where the trail entered. Trim plants and mulch back from the foundation, since they give ants a bridge into the house.

    Optional: Diatomaceous earth barriers

    A thin line of food-grade diatomaceous earth in dry places ants travel (behind appliances, along a threshold, in wall voids) can kill ants by damaging their waxy outer coating. It only works while dry, and you should avoid breathing the dust. Don’t put DE right next to your bait stations, or you’ll discourage the ants from carrying bait home. See our diatomaceous earth guide.

    What about vinegar, cinnamon and peppermint?

    Vinegar is good for wiping away scent trails, but it doesn’t kill the colony. Cinnamon and peppermint oil may deter ants briefly. If you have cats, skip peppermint and other essential oils on floors and counters (here’s why).

    When to call a pro

    • Carpenter ants (large, often black, sawdust-like debris): they can signal moisture and wood damage.
    • Fire ants: they sting and need specific baits.
    • Pharaoh ants: tiny yellowish ants that can split into new colonies when sprayed. They need professional baiting.
    • Ants that keep returning after two or three full bait cycles.

    Always read and follow the product label. Store all pest control products out of reach of children and pets.

  • Pet-Friendly Flea Sprays for the Home: What to Buy (and What to Skip With Cats)

    This post contains affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Learn more.

    Fleas spend most of their life cycle off your pet: in carpet, couch cushions, pet beds and floor cracks. That’s why treating the home matters as much as treating the animal. This guide covers lower-toxicity flea sprays for indoor use, how they work, and the one big mistake cat owners make with “natural” products.

    Quick answer: For dog households, plant-oil home sprays (peppermint, clove, cedar or lemongrass based) plus frequent vacuuming is a reasonable lower-chemical approach. For cat households, be much more careful: many essential oils are toxic to cats. Ask your vet before using any essential-oil product where a cat lives, sleeps or grooms.

    How we chose these

    We did not lab-test products. We compared active ingredients, label directions and pet warnings, and checked them against veterinary and university sources. Every pick below is something to evaluate against your pets, home and label instructions. No pesticide is risk-free, natural ones included.

    Lower-toxicity flea sprays for the home

    1. Vet’s Best Flea & Tick Home Spray

    A plant-based spray whose listed active ingredients are peppermint oil and clove extract. It’s widely sold, inexpensive and made for carpets, pet bedding and upholstery. It’s a reasonable pick for dog homes. Because peppermint and clove are both on veterinary lists of oils that can harm cats, cat owners should talk to a vet first and keep cats out of treated areas until surfaces are dry.

    2. Wondercide Flea, Tick & Mosquito Spray (Pets + Home)

    Wondercide makes essential-oil sprays in several scents (cedar, lemongrass, rosemary, peppermint). The company markets the line for use on dogs and cats and around the home. It’s popular with shoppers avoiding synthetic insecticides. Read the specific bottle’s label: oils differ by scent, and what suits a 70-lb dog may not suit a 9-lb cat.

    3. TropiClean Natural Flea & Tick Home Spray

    TropiClean’s home spray uses plant-derived actives (clove, lemongrass, cedarwood and cinnamon oils in many versions) and is aimed at fabrics, furniture and bedding. It’s good for touch-up treatment between deep cleans.

    4. Food-grade diatomaceous earth (for carpets, as a dust)

    Not a spray, but a common non-chemical option. A very light dusting worked into carpet and then vacuumed up after a few days can help dry out fleas and larvae. Use only food-grade DE, keep pets and people out of the room while the dust settles, and don’t breathe it in. Our diatomaceous earth guide explains exactly how.

    The cat problem: essential oils

    Cats lack a liver enzyme pathway that lets dogs and people break down many essential-oil compounds. Veterinary groups including the PDSA, Cats Protection and Hill’s list tea tree, peppermint, citrus, clove, cinnamon, eucalyptus, lavender, pine, wintergreen and ylang ylang among oils that can be toxic to cats. Exposure can come from skin contact or from grooming residue off fur or furniture.

    • Never apply an essential-oil product to a cat unless the label says it’s for cats and your vet agrees.
    • Keep cats out of rooms you’ve sprayed until everything is fully dry. Consider skipping oil sprays on surfaces your cat lies on.
    • If a dog was treated with an oil spray, don’t let a cat groom or cuddle it until it’s dry.
    • Signs of trouble include drooling, vomiting, wobbliness, tremors or trouble breathing. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435.

    A flea plan that actually works

    1. Treat the pet first with a product your vet recommends. Home sprays don’t replace pet treatment.
    2. Vacuum daily for two weeks, including under furniture and along baseboards. Vibration triggers pupae to hatch, which exposes them to treatment. Empty the canister outside.
    3. Wash pet bedding and throws hot every few days.
    4. Spray or dust the areas where pets rest, following the label.
    5. Repeat in 7 to 14 days. Flea eggs and pupae survive many treatments, so one round is rarely enough.

    When to go conventional

    A heavy infestation, especially in a multi-pet home, may need a conventional premise spray with an insect growth regulator (IGR) such as methoprene or pyriproxyfen, which stops eggs and larvae from developing. If you go that route, choose products whose labels specifically address use in homes with your type of pet. Many permethrin products are dangerous to cats.
