What affects the price

When you call, we look at a few main things to determine your quote. First, we identify the specific pest you’re dealing with, as some require more intensive treatments than others. The size of your property and the extent of the infestation are also major factors; a small apartment needs a different approach than a sprawling suburban home. We also consider whether the problem is limited to one room or if it has spread throughout the structure. These details help us build a plan that actually works for your situation. Exact pricing confirmed free on the call.

About this service

Carpenter ants don't eat wood, but they excavate tunnels inside it to build nests, which weakens the structure of your home. We locate the primary nest and use baits or localized treatments to stop the destruction. If you see large black ants or piles of sawdust, give us a call. Exact pricing confirmed free on the call.
