Signs You Have an Odorous House Ant Infestation

The most likely way to spot an infestation is to see the ants walking around. In summer months, odorous house ants swarm and winged ants will appear around the nest. If you see these swarmers, there is most certainly an infestation.

Odorous House Ant Habits

Odorous house ants like to construct their nests in wall voids, especially around hot water pipes, heaters, crevices and sinks. Outside they prefer to nest in exposed soil. These ants enjoy sweet things, and mostly go inside when their honeydew supply is reduced due to heavy rain.

Do Odorous House Ants Bite?

Odorous house ants do not bite. The only threat they pose to humans is their love for foods — thus posing a contamination risk.

Do Ants Have an Odor?

When these ants are crushed they emit a foul, rotting coconut odor.

How to Prevent an Infestation

Odorous House Ants are attracted to moisture. Be sure to eliminate any standing water in and around your home. Ants can also use tree branches near your roofline to get into your house, so trim trees and branches to make sure they are not touching your home. To prevent the creation of odorous house ant nests, store firewood and other building materials as far away from your home as possible.

How to Get Rid of Odorous House Ants

To remove odorous house ants, baiting is preferred, since they like both sugar and protein-based baits. Insecticide sprays do not work on these ants, as they tend to split up colonies that will simply relocate.
