We have one more month of summer. After that we enter the fall, and that’s when our pest control customers get busy with Critter Quitters. They use them in Rodent Exclusion. This is a fall and winter product as rodents, such as rats, try to get into homes when it starts to cool off. Plumbing vents are a prime way to get into a home. The Critter Quitters internal screen stops this from happening, while at the same time it repairs the vent. Also another fact is that the people that leave Florida in the summer (cant blame them) come back and see what the squirrels have done to their homes while they were gone.
