Why do ants keep coming back after treatment?

Surface treatments that target visible foragers do not address the colony. Ants return because the colony, the moisture conditions, and the structural entry points sustaining them have not changed. Our approach traces activity back to the colony source, assesses the structural and environmental conditions that support it, and addresses those conditions directly. Without treating the source, pest activity will recur regardless of how many times the surface is treated.

Are carpenter ants a structural threat?

Carpenter ants do not eat wood — they excavate it to build galleries for nesting. The structural risk depends on where they are nesting and how long the colony has been active. They consistently exploit existing moisture damage and wood decay, which means their presence is often a signal of an underlying moisture or structural problem. Our inspection includes assessment of the structural conditions sustaining the colony, not just identification of the ants themselves.

What does an ant treatment involve?

It begins with a full inspection to identify the species, locate the colony source, and assess the structural and environmental conditions sustaining activity. Treatment may include targeted baiting, habitat modification, entry point sealing, and sanitation recommendations depending on what we find. The specific approach is determined by the inspection — we do not apply a standard protocol before understanding what is actually happening.
