Today I completed your one time service for wasp. After carefully inspecting the perimeter, I was able to locate the hive in question. I treated the area with a liquid residual solution that will help eliminate the wasp as they moved through the treated area. Please allow 7 to 10 days for best results. Please allow at least 24 hours before allowing the dog outside most especially the area near the hive as there will be some drippage from the solution. Thank you for choosing Green pest solutions!
