Habits
Odorous house ants prefer sweet foods such as fruit and melons. They look for food day and night, with many ants following the same trails.

Habitat
Odorous house ants will nest just about anywhere. Outdoors you can find them under mulch piles, pavers or landscape timers, nesting just below the surface. The indoors offer ideal nesting in walls or under floors, often near a water source.

Threats
Odorous house ants can quickly contaminate food, leaving a signal trail to the rest of the nest. They do not sting or bite.

Prevention
Keep debris piles away from your home to discourage nesting. Seal up cracks and crevices with caulk. Store food in airtight containers and repair water leaks. Odorous house ants can be an unpleasant house guest and a professional pest control agency should be called if you have an infestation.
