Because of this, it is possible they can transmit pathogens from a food source to human food. Thief also ants feed on immature forms of other ants and insects.

    Nests

    Thief ant nests occur in a great variety of locations outside, especially under rocks.

    Thief ants nest in rotting wood and soil. They may also nest indoors in small spaces, including wall crevices, cabinet voids, under countertops and behind baseboards. Because thief ants nest in hidden areas, their nests are difficult to locate. The best way to address a thief ant infestation is to contact your local pest control professional, who can identify the species properly and recommend an appropriate treatment.

    Queens lay eggs, which incubate and take 50 days to a few months to fully develop into adults. Thief ant mating swarms appear from June to September, and these reproductive ants may also be seen indoors in the summer. When thief ants enter homes and buildings, they form trails from the food source to their nests.

    Colonies tend to be smaller than those of other species, but can contain two or more queens and several thousand workers
