Odorous house ants, generally dark brown to black in color, are small ants coming in at approximately 1/16th-inch to 1/8th-inch in size and are related to the ghost ant. Like the ghost ant, odorous house ants also give off a pungent rotting coconut-like odor when crushed and are a fan of protein and sweets. Odorous house ants will also nest in wall voids, under carpets, under mulch, under landscaping stones, and are noted to not be easily managed with bait. Generally, colonies, for which there may be many satellites, must be treated directly. When baiting is required because nests are unable to be found or are out of reach, a trial of a variety of baits may be required until successful control is achieved. If you’re struggling with odorous house ants consider setting up a residential pest service plan or adding ants to your commercial pest service.
