I am planning to cancel your service, for the last several months I have told you the service is subpar and no improvement. I was gone for a week came back to find by entrance blocked by a cob web on the door onto the deck and the door in the barn. American exterminator service never had a problem with spider webs. I can only assume you are using another pesticide for your spray, or a diluted pesticide or not enough pressure for saturated coverage.
