How to get rid of ants…

Here’s what to do when you spot an ant…

  • Watch the ant for a while, see if you can tell what it’s looking for and where it came from.
  • If you kill the ant (or ants) clean the area with a soap or window cleaner (like Windex) to remove the scent.

Note: Resist the urge to just “squish them all”, they give off a scent when squished that will attract others, also you need them alive so they will be able to carry the poison back to the nest.

  • Try to determine what the ant was after, then remove the attractant and clean the area.
  • Look for others (there’s never just one).
  • See if you can determine the path the ants were using and find the entry point (where they enter the house). If you can, fill the cracks or holes where the ants are getting in.
  • Use an ant powder or bait around the entry points (inside and outside if possible).

Note: Hardware stores sell ant killer/bait powders. Do-it-yourselfers use boric acid (Borax) and sugar in small amounts. Here’s a recipe…

  • Most ‘ant killer’ is made up of an attractant and an ant poison. Ideally the ant is attracted to the poison and carries it back to the nest where many ants will be killed.
  • Ants will continue to show up for some time (3-7 days). Keep cleaning the trails and the entry points.

Most common ants live outside in the ground, in nests or ant hills. Several hills and nests can make up one colony. The queen ant (which can live up to 30 years) is in charge and is responsible for making the new ants. In the spring, as things start to warm up, ant colonies send out scouts to forage for food and fuel. These foraging ants leave a scent trail so they can find their way home and so other ants can follow. While foraging ants may be attracted to food material inside your home.

You will never kill all the ants, they will make more! You can only hope to keep them to a minimum in your home. Most attempts to control ants are temporary at best so be careful with poisons and be wary of false claims.

ps/ Ants perform many ecological roles that are beneficial to humans, including the suppression of other pest populations, aeration of soil [source] and an occasional Pixar movie.


  • This article is written in the most general, non scientific terms for people who have spotted a few ants in their home and would like to get rid of the ants.
  • This article is not meant to deal with major ant infestations in out buildings or ant colonies near bio waste facilities in the Florida everglades (see: Empire of The Ants 1977 for more on that type of infestation).
  • Ants are everywhere. Ants thrive in all ecosystems, and form 25% of the terrestrial animal biomass on earth.
  • Getting rid of all the ants in your yard is impossible. However you may be able to stop them from showing up in your home.

Good luck!
