Thought we had a problem with ants. Gentleman came by, drilled a few holes in the house, sprayed some dust like chemicals and said all set and handed us a bill. Weeks later issue was still with us.. came back, drilled some more holes and again put some dust in.. all set??? OH NO!!.. Had work done on the area that he treated on our home as we were not sold on his "all set" mentality. When they took the wood off there were literally thousands of carpenter ants eating away at our home. The workers had never seen so many ants and this was al in places where they treated and said we were "all set",,, Also came to find that these same ants had taken refuge in other areas that were supposedly treated. It was sickening. Called them personally to come and see what their job didn't get!! Even took photographs of the colony of ants that had we left as being "treated" would have destroyed our home.. Warmer weather coming and ants seem to be back again. looking hard this time for someone who knows.
