As far as Cummings effectiveness against bugs in the house, I'm neither here nor there. We have a contract for them to come out every 2 months. We still have our ant problem and we still get bugs in the house. The annoying thing for me is the bug guy who stops by our house 2- 3 hours before our scheduled appointment time. Is it better than being late? I'm not so sure it is. The bug guy calls and leaves messages on our voicemail that he is at our house and wants to treat the house sooner (of course it always a time that is not convenient for me). When I explained to the scheduling lady the concept of an appointment (which is I schedule a time that works for me and they schedule a time that works for them/bug guy), I was told they would speak to him about arriving early. Now he just waits in our driveway until I get home. Perhaps I am being paranoid but the guy gives me the creeps! As soon as our contract is up, it will be 'Smell you later, Cummings!!'
