Always do a great job. Have an older home, that Kevin gives a good spray around windows door etc. Will see a dead bug or two a couple days later, so prevention of a mass migration is important. I like that they spray the complete exterior windows and doors etc, to create a bug barrier. Sprays in cement block wall cracks and around my shed. Kept in mind to protect my dogs if I didn't happen to be home, and not spray in the doggie area. Monthly cost was reasonable. Courtesy call the day before, always on time.
