Critters were in the walls of our home. The first visit CPCS checked all avenues which they could enter and in return placed bait in the area in a safe manor that would not harm our pets or could not have any access. The entrances were appropriately plugged so no more free-range for critters. They cleaned and disinfected the area's the critters were located for an additional fee and checked weekly for four weeks. Russ and his team did a fantastic job eliminating critters!
