Technician was courteous and knowledgeable, however my outdoor curtain that I had just washed and re-hung got streaks on it from the spray used on a hornets nest.. I should have supervised I guess and told him to move the curtain back before he sprayed. I washed it again and it came out. I thought he would remove the hornets nest but it is still there. Also I would appreciate a technician coming into my home wearing disposable booties on his shoes.
