Behavior

Odorous house ants feed primarily on dead or alive insects, honeydew, plant secretions and seeds. An odorous house ant colony may consist of several colonies with 100 to 10,000 ants and many queens. Outside, the odorous house ant will build nests in exposed soil and under such objects as lumber and bricks, even in honeybee hives. Inside, nests are usually found near sources of moisture in wall voids, near water heaters, plumbing and even under toilets. Odorous house ants love the sweet, carbohydrate-rich honeydew produced by aphids and scale insects, and during wet weather or autumnal leaves falling, when they don’t have access to honeydew, they will enter buildings looking for food.

Treatment:

The first order of business with odorous house ants is to seek out their nests. Dusts and baits can be effective, but for a comprehensive treatment that will locate and contain all the hidden places this ant can nest, call Clark Pest Control.
