Odorous House Ants

 

DESCRIPTION:

Odorous House Ant workers are monomorphic and are about 1/16-1/8 inches long. The body is brown to black, usually they’re black, and they do have a stinger. Workers emit a rotten, coconut-like odor.

 

DAMAGE:

External indication of infestation from Odorous House ants is usally indicated when there are is a presence of small openings on the surface of the wood. Here the workers will expel debris which consists of sawdust-like shavings and fragments of insulation and insect body parts. They prefer to a hollow out soften wood that is associated with moisture problems and fungus.

 

HABITS:

These ants usually construct their nests in wall voids especially around hot water pipes and heaters, in crevices around the sink, cupboards, etc. These ants prefer sweets, high protein foods and foods with grease like meats and cheeses.

When workers are alarmed, they run around in an erratic manner with their gasters/abdomens raised up in the air.

 

BIOLOGY:

The colonies will be composed of about several hundred to 10,000 ants. There are usually many queens in a colony. Developmental time of the ant is usually between 34 and 83 days. Colonies will produce 4-5 generations a year. Although mating is done both inside and outside the nest, the first swarmers appear from May to mid-July. The workers and queens live for several years. Individuals from different colonies are not hostile to one another and workers normally move along trails.
