Pharaoh ants (Monomorium pharaonis) can infest homes, office buildings, apartments, commercial bakeries, factories, hospitals, and wherever food is handled or stored.
The main challenge of dealing with pharaoh ants is that they can spread quickly throughout the building. If disturbed, part of the pharaoh ant colony migrates to new locations to establish several new colonies. This behavior is called budding. Budding occurs due to a number of reasons such as overcrowding, seasonal changes in the building’s central heating and cooling system, or applications of repellent pesticides or cleaning agents.
