The Pharaoh ant is one of the smallest and most difficult ants to control. Also known as tramp ants, this invasive species constructs temporary colonies that splinter off and form new colonies when disturbed. Due to their splintering ability, Pharoah ant infestations can spread quickly in homes and buildings, forming colonies with over 300,000 workers and multiple queens. These ants prefer to establish nests in hard-to-reach locations like wall voids, subfloors, and attics.
