The standard treatment to control carpenter ants is to apply insecticide into exterior wall voids, completely around the structure, thereby creating a barrier that worker ants must cross to forage for food. Wall voids are the spaces between wall studs that are usually filled with insulation. Ants use these avenues to enter and exit the structure. Wall void treatments generally require drilling into these spaces and may be beyond the ability of most homeowners.
Perimeter sprays are often used in conjunction with wall void treatments for added protection. Typically, a perimeter treatment involves spraying an insecticide such as Termidor Insecticide around the base of the structure where the siding overlaps the foundation (see photo right).
The third, and newest tools, are carpenter ant baits. Baits designed for carpenter ants may be used around the base of the structure or indoors (check label for registered uses).
