Ant Baits are the only effective control method for control and elimination of the Pharaoh ants. Residual treatments generally should not be used in Pharaoh ant control because they result in colony budding, contaminate bait stations and kills only the foraging ants.
Colonies of the Pharaoh Ants average 3,000-4,000 ants with several queens. Pavement ants normally nest in soil; however, they occasionally nest indoors in walls, insulation and under floors. Colonies will move near a heat source in winter.
