It is wintertime, and ant activity is declining in much of the U.S. But for some regions, winter brings an unexpected increase in ant calls. While many ant species are hunkered down waiting out the winter, some species, like pharaoh ants (Monomorium pharaonis) can pop up inside structures.
In warmer months, ant treatment typically involves locating any exterior satellite colonies and some combination of liquid residual treatments and baiting. In the winter, however, these satellite colonies often contract into single colonies inside wall voids, attics, subfloors and other areas inside structures to escape the cold weather.
Controlling pharaoh ants and similar species in these situations can be difficult, especially when customers only see a few ants here and there. Worse, customers often self-treat or wipe up foraging ants and their pheromone trails. Pre-baiting with syrup or honey can aid in finding the colony, although it’s a tough sell to get customers to do this.
After locating colonies, you can use various treatment methods to eliminate them. Dusting, liquid residuals applied with compressed air sprayers or aerosol-generating machines, aerosols or baits can also be effective, depending on the situation.
