We received a 10 minute advance notice that AAI would be at our house to spray. We were out of town and unable to respond until after the service person had already been at our home. I can't imagine what he could have possibly done, since our gates were locked for both our front and back yard. We were charged for spraying when he was unable to get in to the area of problems. I am not satisfied. I would like an email or text at least 24 hours in advance so I can unlock gates if I need to be gone!
