Hello! Today I completed your one time service for carpenter ants. Upon arrival we spoke about seeing evidence of carpenter ant activity around front porch. There was some dirt between the stone part of porch and on the wood in between. No active activity seen during this visit. I treated exterior perimeter and around front porch of home with a liquid residual for carpenter ants and other general pests. Please allow 10-14 days for treatment’s best effects. Thank you for choosing Green Pest Solutions!
