Rodent extermination is great, but it doesn’t stop unwanted furry visitors from finding their way into your home. Many pest control companies offer rodent exclusion services. Exclusion involves sealing cracks around your home to decrease the chance rodents and pests can find their way inside.   Rats can squeeze into holes as small as half an inch. Exclusion services are the key to keeping your home rodent-free. Services typically include:  • Sealing cracks around your home • Installing door sweeps and weather seals • Installing vent covers, chimney caps, and plumbing caps
