Odorous House Ants have antennae with 12 segments, and like Carpenter Ants, range from black to a red/brown. However, these pests are much smaller than their woodworking cousins, only measuring about 1/10 of an inch long.

Both workers and female Odorous House Ants can live for several years, with females laying one egg each day. Hatchlings reach maturity in about 24 days. Odorous House Ants art partial to honeydew melons for their dietary staple in the wild, and typically seek out sweets when infesting homes.

Ordorous House Ants enemy within the ant family, is the Argentine Ant. When they encounter each other, Argentine Ants will often drive Odorous House Ants from their nests.
