Rodent control is a major issue for many homeowners. Rats and mice have the ability to transfer diseases, contaminate food and cause structural damage. They are also accomplished chewers, known for gnawing their way through barriers with their powerful front teeth. Rats and mice cause expensive damage each year. The best way to prevent this damage is to prevent rodents from entering your home in the first place. Rodent-proofing your home is the first part of a multi-step approach.
