Good afternoon, Nice to meet you today I was here for your initial service. I inspected tree, hornets were present but no nesting was found. We can’t treat unless a nest is present. Most likely they are just using the wood from the trees to build a nest elsewhere. For now please monitor and let us know if nesting occurs. Carpenter ants were present at the trees, I placed bait for them. On the exterior of the home I installed termite monitors and applied a liquid residual to the perimeter. We will be back in 30 days for the next service. Thank you for choosing green pest solutions!
