Every year we seem to be more & more delayed with the semi-annual service. What used to happen in early spring now happens in summer - a bit frustrating when you receive a postcard alerting you to the service and it takes 4-6 weeks to happen. The individual who came this year announced his arrival and indicated he would call before he left the premises which he did not so we were unable to discuss the ant problem we had called earlier about. Time will tell what happens in the fall with the next spray.
