FAQs About Pet Safe Ant Killers

What Types of Insecticides are Pet-Friendly?
There are many natural ingredients that are both pet-safe and toxic to insects. Certain plants and oils can kill ants as well as natural powders, like diatomaceous earth.

Diatomaceous earth has actually been recommended by the Canadian government as an alternative to chemical sprays.This talc-like powder is actually the fossilized remains of marine phytoplankton. The bugs come in contact with it, it impacts their waxy outer coating and turns their insides into bug jerky. While toxic to insects, diatomaceous earth is not poisonous to mammals. In fact, we can actually eat food-grade diatomaceous earth.

Other pet-safe, natural ant killers include:

  • Essential oils, like thyme, clove, peppermint, geranium and wintergreen
  • D-Limonene
  • 2-Phenethyl propionate
  • Cedarwood oil
  • Borax or boric acid

These natural ingredients are safe to use around pets, and they get the job done by killing any ants that come in contact with them.

Are Pet-Safe Products as Effective as Regular Poison?
They can be, but it really depends on how you apply the product. Baits with borax, for example, can be taken back to the nest and shared with other members of the colony. Within days, all of the ants are dead, including the queen.

Sprays can be really effective against ants, but they won’t be able to bring the spray back home to the nest. With that said, sprays can be a really great option for killing ants that are just checking out your home to see if there’s any food.

Why are There Ants in My Home?
This is a question that everyone asks when they find ants in their homes. Many people blame themselves and wonder if their homes are dirty. The truth is that ants invade all types of homes. You can have the cleanest home on the block and still deal with an ant invasion.


Because homes all have three things ants want: food, water and shelter.

It doesn’t matter whether you live in the suburbs, a city or out in the middle of nowhere, ants can invade your home. A tiny crack in a window sill and a few crumbs on the kitchen counter are all that’s needed to attract ants.

How Do You Prevent Ants?
It can be difficult to prevent ant invasions. They’re resourceful, crafty insects that can fit into the tiniest of cracks.

Prevention should start with access. This means sealing any holes or cracks along:

  • The foundation
  • Window sill
  • Doorway
  • Walls
  • Floors
Sealing cracks and holes will keep ants from getting into your home in the first place.

Laying down ant bait or granules along the perimeter of your home can also stop ants before they enter your home.

Along with sealing cracks and holes, you’ll also want to:

  • Keep unrefrigerated food in sealed containers
  • Keep a tidy kitchen
  • Keep garbage and food scraps out of reach
Can Pet Safe Products be Applied to Vegetable Gardens?
That really depends on the product itself. The product label should provide warnings or information about use in or near vegetable gardens.

Some products, like food-grade diatomaceous earth, can typically be applied near or in vegetable gardens. It’s not toxic to pets or people – or other mammals for that matter.

Products that contain essential oils or sulfates may or may not be safe for vegetable gardens. Some essential oils can damage plants, but most should be okay for use in gardens. Again, it’s important to read the product’s label and follow the directions accordingly.

Will Pet-Friendly Ant Killers Destroy the Colony?
That depends on the product that you’re using. Pet-friendly ant killers can destroy the entire colony if you’re using a bait-style product that the ants will take back to the nest.

You’ll find some baits and traps that contain borax. It works in a similar way to conventional baits with harsh chemicals. The worker ants take the bait back to the colony, share it with other worker ants, and then share it with the queen. Eventually, the entire colony collapses after the queen dies.

Why Choose Natural Insecticides?
It’s true that natural insecticides can take longer to work, and they may require diligent re-application to eradicate your ant problem. But there are many benefits to choosing natural products.

Harsh pesticides have been blamed for destroying bee populations. They work well, but they also kill beneficial insects in the process. Without bees and other pollinators, we won’t have any crops left.

Natural insecticides won’t harm the environment, and you don’t have to worry about keeping the kids and pets out of the yard.


If you have pets in your home and an ant problem, you may be leary of using harsh pesticides to fix the problem. It can be a challenge to get rid of ants in the house, but these products can help – without hurting the environment or your pets. Using products that are dog safe and cat safe means that your animals can enjoy living in their homes even while treating your ant problem.
