Odorous House Ant

Characteristics – 
Size:  About 1/8-inch long.

Color:  Brown.

If crushed, the workers give off a rotten coconut odor, hence their name.

Behavior –  Odorous house ants may develop huge colonies containing thousands of workers and numerous queens. This species may be difficult to control and does not feed much on ant baits. The keys to control are to find the colonies and subcolonies and treat them directly. Regular inspections and service are necessary to find and treat new colonies as they move in from neighboring properties. The services of a professional, such as Carson, are very helpful when encountering these ants.

Habitat –  This species is common in California north to Washington and is the most common pest ant in the mid-south region of Arkansas and West Tennessee. They may be encountered occasionally throughout the Midwestern United States. These ants nest outdoors under items on the ground, within landscape mulch, beneath loose bark on trees, under ground cover, in potted plants, and within piles of items, such as lumber, firewood, or bricks. Nests may readily be established inside homes, in walls, beneath carpeting, and other suitable voids or spaces.

Tips for Control –  This ant can be difficult to control because it establishes multiple subcolonies and may nest in such a wide variety of sites. The keys to control are to find the colonies and subcolonies and treat them directly. Where the colonies cannot be found, baits may be attempted; however, several baits may be required before positive results are seen. Regular inspections and service are necessary to find and treat new colonies as they move in from neighboring properties. The services of a professional, such as Carson, are very helpful when encountering these ants.
