Odorous House ants

Physical Appearance

      The Odorous House Ant, or more commonly known as “sugar ants” is very tiny; less than 1/16 inch long, it is brown to black in color. It has 12 antennae segments, and only one node (waist), with an uneven thorax when viewed from the side

They also produce a foul smell like “rotten coconut” when crushed, hence the name.

The Odorous House Ant is also one of the hardest to get under control, because they are a multi queen ant colony. So when you use a generic ant spray that has a repellent in it, it will fracture the colony, and they will set up shop somewhere else in your home. That’s why when you spray in the kitchen they show up in the bathroom or bedroom. You’re actually multiplying your problem.

Nesting Habits

Indoors, Odorous House Ant nests may be found within wall voids, in crevices around sinks and cupboards, and near hot water pipes and heaters. Outside, Odorous House Ant nests are usually established in shallow, exposed soil beneath brick, board, or stone. Odorous House Ants are most likely to enter the home in the autumn time or during rainy weather, when the outdoor sweet food supply is reduced.

Feeding Habits

Odorous House Ants forage both day and night. They prefer sweet items, including syrup, candy, honey, and sugar, but will also feed on insects, seeds, and plant secretions. 


Females Odorous House Ants lay at least one egg per day. Once hatched, it takes about 24 days for the young Odorous House ant to reach adulthood. Colony size ranges from 100 to 10,000 ants.
