Hello.. I live in a 5 year old townhouse(Toll brothers) . away from water, away from big trees. very small yard on the back. I got this visit from a local pest control guy ( MOXIE ) and I fell for his talk and signed up for an annual contract.. but now i am wondering.. i don’t have any visible pest problems – other than the occasional ants i see in the kitchen. Do i really need a professional pest control service? are there any invisible pests lurking behind my walls?
