What to Know before You Buy Any Ant Killing Products

Before you grab just any ant killer off the shelf, there are a few considerations you should keep in mind.

Kill the nest, not just the ants– First and foremost, you want an ant killer that allows the ants to get back to the nest and carry the poison there with them. You may not always be able to find the nest on your own, and you need a pesticide that will take care of that for you.

Get the right treatment for your ants– You also need to know the kind of ant you are dealing with. Terminix reveals that knowing the type of ant will allow you to better treat for them. Not all ant killers will treat for all types of ants, so pay careful attention to what bugs are listed on whatever pesticide you are interested in.

Protect your kids, pets and the environment– Another thing to keep in mind is that some pesticides may contain chemicals that are harmful to the environment, to your pets or to your household, and you need to know when it is safe to use them and when you should go with something else.

If you want something that is much safer to use around sensitive animals and children, then this is the way to go. Bugs R Done has crafted a mostly natural treatment for ants and other bugs, and it uses potent citrus fruits to kill them effectively.

That citrus smell gives it a pleasant scent and ensures that you and your pets should not be bothered by the smell at all.

View On Amazon

This Stormtrooper spray is some of the most effective ant killer on the market, but it is also some of the most expensive. It releases a fast-acting foam that gets deep into the ants’ nest and takes out bugs you could not otherwise reach. It is meant to be used directly on the nest, so if you don’t know where the nest is, you may be wasting your time spraying this around your house.

It kills bugs very fast, and they usually won’t have time to take the poison back to their nest, so finding the nest is important. Terro says to look for where the ants walk to after finding a food source and to also keep an eye out for swarmers and wood shavings as signs of the nest.

  • Foam covers a large area quickly and effectively


  • Incredibly costly
  • Needs to be applied directly

Max Ant & Roach Killer
