Every home is different and has varying features, characteristics, building materials, locations (ie: next to a lake), etc., that need to be taken into account when treating and locating/preventing pest problem areas. As your pest professional, Effective Pest Services knows it is important to break the life/egg cycle of the pests. This is why we treat quarterly. We know after a few months the products will break down and need to be reapplied to keep working. It is important to break the life cycle to prevent the eggs that hatch where we can’t spray them (ie: behind your siding, etc), from maturing and producing eggs for the next generation of pests. To protect your home and our company reputation, we require a one-year service agreement. The last thing we want is you telling your neighbor, it only worked for a couple of months. We know by reapplying the products and giving you a warranty, we can guarantee the results and protect your home and our reputation as a pest control company. We want you to get the most for your money and we want you to recommend us to your friends and neighbors.
