Catching the rats is only part of the job. In order to complete the job, I have to find and repair all of the entry points, and in many cases, clean up after the mess that rats have left behind. When rats make your attic their home, they also makes your attic their toilet. Rats leave behind quite a bit of biohazardous waste, in the form of droppings, urine, oils, hairs, and other body wastes. These wastes not only make your attic smell bad, but they can pose a biohazardous risk, and furthermore, serve as an attractant to other rats in the area. Once rats have lived in your attic and established their scent, that smell serves as a signal to other rats indicating that your attic is a great place to live.

The longer rats have lived in your attic, the worse the mess is, but even short-term attic use can leave behind the telltale odors and pheromones that rats leave behind. I know for a fact that once rats leave their scent behind that it serves as an attractant to new rats. I've seen many homes in which people have been rat-free for several years, but once the problem starts, it doesn't just "go away". This is not only because rats and their offspring return to the same denning grounds, but because of the smell that they leave behind. Rats are notorious for using chemical signals (pheromones) to alert other rats of the good places to go. Eliminate these attractant odors by having your attic sprayed with BioShield.
