What do odorous house ants eat?

Odorous house ants primarily subsist on honeydew to survive and are generally attracted to homes that have aphids and other scale insects nearby that produce their favorite food source.

They also will invade homes in search of water and sweets. Therefore, it is important to clean up crumbs, store pantry items in sealed containers, repair leaky pipes, and resolve any moisture issues.

Are odorous house ants dangerous?

Odorous ants are considered a nuisance pest because of the unpleasant odor they leave behind. These ants are not harmful to human health. They can bite like other ants, but they generally do not bite people. Furthermore, their small size and lack of venom mean that even if you are bitten, it won’t hurt very much.

However, while they don’t generally cause direct harm to humans or pets in homes they infest, they can indirectly harm them by contaminating food items. They seek out sugary foods found in any home they inhabit, and their small size allows them to squeeze into the smallest holes and cracks to access a viable food source.

Why do I have an odorous house ant problem?

Like any other pest, odorous house ants invade homes primarily in search of food and water in order to survive. These ants are also known to invade during periods of heavy rainfall in search of a warm, secure place to stay until the weather improves.

While they can get inside through open windows or doors, they can also gain access through small cracks in your home’s foundation. Odorous house ants are known to target homes with moisture problems where water is easily available.
