The best pet-safe pesticides for your home and yard

Updated September 26, 2023

pet safe pesticides

When it comes to selecting pet-safe pesticides for your yard, you can’t be too careful. To help, we’ve built a list of low-risk treatments that are safer options for you and your pets! We started our search at the National Pesticide Information Center and narrowed our list to products identified as low-risk by the Washington Toxics Coalition (now Toxic-Free Future) and Our Water Our World.

Then, we focused on the absolute safest pest-control products possible. We evaluated those low-risk products against the EPA’s conditions for minimum-risk pesticides to find the products with the least toxic active ingredients.

🚨When we say pet-safe insecticides, we mean pet-friendly products used to treat the home. Never spray these products directly on your pup. They are not bug repellents for a dog’s body.

Why using pet-safe pest control matters

In a world with genetically modified organisms and big agriculture, it’s hard to avoid exposure to harmful pesticides. These chemicals are everywhere, and their residue is hard to get rid of. Replacing harmful pesticides with low-risk ones — or natural alternatives — may reduce your exposure.

Certain lawn chemicals linger on grass, plants, and outdoor surfaces for up to 48 hours after application. What’s even scarier is that they usually make it all over the inside of your house, too. Ever sprayed weed killer in your yard? Those chemicals are likely all over your kitchen floor. That’s because chemicals hitch a ride into your house on human and pet feet. If your dog eats the grass or licks themselves, those chemicals collect in the gut, which is even worse.

The good news is that it usually takes years of exposure before chemical residue builds up enough to cause problems for you or your pet’s health. The bad news is that these chemicals aren’t going anywhere. Case in point: In 2019, the EPA refused to ban a pesticide linked to neurological damage in children because of its importance to U.S. agriculture.

What to look for in pet-safe insecticide

There are some must-have ingredients to look for when choosing a pet-friendly bug spray for your home. We recommend using minimum-risk products as outlined by the EPA. They should all have the following ingredients:

  • Commonly consumed food commodities (this means they are food-grade)
  • Animal feed items
  • Edible fats and oils (essential oils like cinnamon oil, clove oil, and cedar oil)

What to avoid

There are several ingredients to avoid when shopping for a suitable insecticide:

  • Organophosphates (such as malathion and disulfoton)
  • Snail and slug baits containing metaldehyde
  • Pesticide/fertilizer combinations

🚨Never use a product like DEET around pets. Many ingredients used in typical household products are extremely toxic for dogs and are linked to cancer.

The impact of pesticides on pets and people

Here are just a few important findings to consider. It’s not a pretty picture.

  • Heart disease. Long-term exposure to pyrethroid-based repellents and shampoos may increase heart disease in adults.
  • Stronger pesticides. Today’s pesticides are 48 times more toxic to bees and insects than they were before 1990.
  • Lymphoma.  Pets are at risk of lymphoma due to exposure to glyphosate residue in commercial pet food. The use of professionally applied lawn care pesticides raised the risk of lymphomas in dogs by 70%, according to an older study. Home lawn pesticides have also been linked to cancer, nervous system issues, and other conditions in cats and dogs.
  • Bladder cancer. Scottish terriers exposed to herbicides were 4-7 times as likely to develop bladder cancer.

Interestingly, many of the studies we read did not find the same correlation between flea products and adverse effects for pets though “old-school” flea medications may be harmful. Our veterinarians generally discourage the use of flea shampoos and some flea powders and recommend medication instead for fleas and ticks.

‘All-natural’ products aren’t created equal

It’s not enough that toxic chemicals are everywhere. But it’s even harder to know what’s safe and what’s not among products labeled all-natural. Product labels and marketing can be pretty misleading, if not downright deceptive.

A great example of this is the presence of permethrin in sprays labeled all-natural and organic. First, permethrin is a synthetic version of a naturally occurring pesticide. All-natural? Meh. Secondly, the EPA classified it as likely to be carcinogenic to humans if ingested.

Use high-powered pesticides only as a last resort 

Look, we get it. Sometimes the pest problem is so bad that it takes professional-grade treatment. For families that live in warm or human climates, the options come down to staying indoors most of the year or treating their yards for pests like mosquitoes.

The best thing pet owners can do to protect themselves, their pets, and their families is to use minimum-risk pesticides as much as possible. Some pest-control measures like traps for rodents are typically covered by an enclosed box so as not to harm pets or children.

In cases of infestation, you may want a professional pest-buster to come and spray your home. When looking for an exterminator, read reviews and look for one that uses pet-safe products.

Signs of pesticide poisoning

One of the biggest risks of using toxic ingredients is insecticide poisoning. Even safe-to-use products can be unhealthy for your pup when ingested, inhaled, or exposed to the skin in large doses.

Look out for these signs of insecticide poisoning:

  • Drooling
  • Gagging
  • Nausea and vomiting
  • Diarrhea
  • Loss of appetite
  • Paranoia or agitation
  • Tremors and seizures
  • Convulsions
  • Breathing difficulty
  • High heart rate
  • High body temperature

⚠️ If you suspect that your dog ingested something toxic, notify Animal Poison Control immediately: (888) 426-4435

Pesticide poisoning prevention

The rule of thumb is to keep your dog away from sprayed surfaces for at least three days. The following are some insecticide-poisoning prevention methods:

  1. Put your pup in a different area while you spray
  2. Remove any of your dog’s bowls or toys from the garden
  3. Don’t mix products
  4. Make sure your neighbor is using puppy-safe products, too
  5. Wipe down your dog’s paws before they come inside
  6. Store products out of reach of your dog

Alternatives to pesticides

You could also try swapping pesticides for these alternative, pet-friendly pest control ideas:

  • Diatomaceous earth. Found at many garden centers, it repels crawling insects.
  • Neem oil. Easily available, it disrupts the life cycle of insects at any stage.
  • Essential oils. Peppermint-thyme-oil repellent repels flies, fleas, mosquitoes, and more.
  • Homemade insecticidal soaps. Sprayed directly on affected foliage, it keeps away common garden pests.

How to spray your home and yard

It’s important you know how to correctly spray your home and garden. The first thing to do is follow the “directions for use” on the bottle. Different products have different application methods.

👉 Natureshield is applied through an irrigation system. Apply Summit Mosquito Dunks to water throughout the garden. Other products come as a spray bottle.

Before applying products for home defense, cover utensils and countertops. Apply the product to areas where pests hide, like pantries, attics, cracks, and crevices.

In the garden, spray the grass, crevices on the patio, and other plant areas. Aphids tend to hang out on leaves while earwigs hide in mulch. Don’t apply too much product to the areas of the garden where your dog hangs out.

Frequently asked questions

How long should I wait after spraying before I let my pet outside?

Most product labels advise that you and your pets should keep off sprayed lawns or surfaces for six to 24 hours. Studies, on the other hand, say that chemical residue can be found on surfaces up to 48 hours after application — even if it rains.

What happens if a dog smells pesticides?

Pesticides and insecticides used indoors and outdoors are basic irritants for pets and people. For dogs, exposure might include symptoms like diarrhea, drooling, vomiting, or nausea.

What happens if my cat licks pesticides?

While this depends on the chemicals used in the product, certain insecticides that contain organophosphates, carbamates, pyrethrins, and pyrethroids are toxic to cats. In addition to the typical signs of exposure, cats may also experience muscle tremors and seizures. Contact the Poison Pet Helpline if you suspect pesticide poisoning.

How long does it take for pesticides to affect a dog?

With dogs, signs of exposure to pesticides depend on the chemical used, the amount of exposure, and the individual dogs. Symptoms can start within a few hours or up to a few days.
