Habits

Odorous house ants like to eat sweets, especially melon and other insects.

Habitat

Typically living for several years, these ants make their homes in exposed soil and wall cracks.

Threats

These ants do not pose a public health risk, but they can contaminate food and should be avoided.

Prevention

Eliminate standing water. Pests such as odorous house ants are attracted to moisture. Keep tree branches and other plants cut back from the house. Sometimes pests use these branches to get into your home. Make sure that there are no cracks or little openings around the bottom of your house. Sometimes pests use these to get into your home. Make sure that firewood and building materials are not stored next to your home. Ants like to build nests in stacks of wood.
