What are odorous house ants?

To the naked eye, odorous house ants have a very generic appearance. They are a small species with workers growing from between 1/16th and 1/8th of an inch in length and are a black or brown color. Their most distinctive characteristic and how they are most often identified is the foul-smelling odor they emit after being crushed. The odor is often compared to a rotting coconut. As their name suggests they are common invaders of homes and other structures.

Why do I have a problem with odorous house ants?

Odorous house ants are living in your Washington yard or home because it is providing them with easy access to sources of food and water. These ants feed on a wide variety of foods but prefer foods that are high in sugar. They are very fond of honeydew, a sweet, sticky liquid produced by aphids and other garden pests. Their fondness of sweets is why they are also referred to as “sugar ants.”
Odorous house ants forage for food in flower and vegetable gardens, in open containers of trash, in compost bins, and in outdoor eating areas. These ants often find their way inside homes either while foraging for food or while trying to escape harsh weather, especially during periods of rain.

Where do odorous house ants nest?

In the Pacific Northwest, odorous house ants create neats in both indoors and outdoor locations. Outside they nest in soil under mulch, fallen trees, woodpiles, or rock piles. Inside they prefer to create nests near areas of moisture, in wall voids near hot water pipes or sinks, inside heaters, and in crawl spaces. They also like to place their nests in pieces of wood that were previously damaged by termites or other wood-damaging insects.

Are odorous house ants dangerous?

Odorous house ants are nuisance ants. They invade in large numbers, are annoying to deal with, and will contaminate food. But they cause no significant health risks to people or damage to property. It is important to note that their presence in or around your home may be an indicator of a moisture problem that should be addressed.
