How do you treat Carpenter Ant infestations if the nest is not found?

When dealing with Carpenter Ant infestations in situations where the nest can't be located, injecting insecticide into selected areas of the home is an effective treatment method. Carpenter Ants tend to create satellite nests, often in wood that is damp or decaying, and they can also travel significant distances from their main nest. By injecting insecticide, pest control professionals can target areas where ants are commonly seen or where they may be entering the structure. This method deposits the insecticide directly into potential hiding places and pathways, allowing it to affect the ant population even if the primary nest remains undetected.

Using only bait traps, sealing entry points, or high-frequency sound devices are less effective in this context. While bait traps can be helpful for monitoring and controlling populations, they do not provide immediate relief or targeted treatment if the source of the infestation is unknown. Sealing entry points is a preventive measure rather than a treatment and would not eliminate an existing infestation. High-frequency sound devices do not have proven effectiveness against Carpenter Ants.
