Odorous House Ants


Actual Size: 1/16″ to 1/8″

Characteristics: They are brown or black. The best identifying characteristic is the “rotten coconut” smell they produce when they are crushed; hence the name.


  • Odorous house ants have multiple queens.
  • They often form many colonies by “budding” off the original colony.
  • Outdoors they usually nest under stones, logs, and planters.
  • Indoors, they usually nest in wall voids near heat sources.
  • They prefer sweets but will eat almost any household food.
  • They invade structures during heavy rains when the honeydew of plants is washed off.


Odorous house ants are the culprits behind most ant infestations in homes each year. Their colonies can grow to be quite large and new colonies are formed easily. Also occasionally known as stink ants or coconut ants, odorous house ants emit a foul smell when crushed. Kitchen pantries and cupboards are often the preferred target for these ants, who are constantly in search of sweets and proteins to feed on.

Odorous House Ant Habitat

When they are outside, odorous house ants are often found in exposed soil or under stacks of firewood. They most often make their way inside looking for food, which is why they are typically found in kitchens. When they nest, odorous house ants prefer areas with moisture—wall voids near water pipes, heaters, leaking fixtures, and damaged wood are thus all ideal habitats for them.

Behaviors of Odorous House Ants

Odorous house ant colonies can grow to have thousands of members, which is why getting rid of them completely can be so difficult. Like many species of ants, there are worker and scout ants who seek out food away from the nest to provide for the queen. Scout ants leave an invisible scent trail back to their colony for other ants to find food sources, which is why these ants can spread so quickly.

Odorous house ants are infamous for being so difficult to exterminate. Because they are tenacious and spread so easily, professional help is almost always needed to ensure their complete removal.

What You Can Do About Ants

Can you get rid of ants yourself? Most do-it-yourself ant control products only kill the ants you see, not the colonies themselves. Also, home remedies don’t account for the fact that different kinds of ant infestations require different treatments. The best you can do is to eliminate any potential food sources by keeping your home or business clean. However, if you’re still having issues, you’ll need to contact a pest control specialist like Pest Defense Solutions to seek out and destroy nests to help prevent these pests from returning.
