"Dave was excellent. He was professional, honest and thorough. I thought I may have squirrels in the house because I heard scratching above a ceiling and saw a squirrel climbing my chimney with acorns in it's mouth.  
Dave inspected all the outside areas of my house and looked in my attic. He found no evidence of squirrels or bats or anything else (other than a few mice that I can take care of).
He screened off my two gable vents and recommended securing a couple of other entry prone areas which I can do.
I highly recommend Colonial Pest Control.

Pest Control FAQs, answered by experts

They’re a nuisance, but silverfish aren’t nearly as dangerous as other pests like cockroaches, mice, termites or bed bugs. They don’t carry diseases that humans or pets can catch, and they don’t cause widespread destruction like termites or rats. Silverfish are small and find it very easy to get inside any exposed foodstuffs. Like weevils, you may find them in unprotected flour, cereal, grains, bread boxes, chip packages and more. They will happily nibble fabric and paper as well, so they can cause damage to furniture, clothing, books, bedding, curtains and other materials.

Yes, badgers are aggressive mammals, which is why it’s important to safely remove them from your home or garden area as soon as possible. Keep in mind though, badgers rarely attack pets or people, but their sharp claws and even sharper teeth can make them dangerous if they feel threatened.

Adult fleas can live a few days to a couple of weeks on your couch if they don't have a host to feed on. However, flea eggs, larvae, and pupae can live much longer, even several months, with the right conditions. That is why it’s vital to eradicate them from your couch and other upholstered furniture.

Trained eyes spot subtle indicators amateurs might miss, ensuring issues are addressed before they escalate.

Groundhogs have a strong aversion to powerful scents, including garlic, ammonia, vinegar, hot peppers like cayenne, and predator urine. Various herbs such as rosemary, lavender, basil, mint, sage, thyme, and oregano can also act as deterrents. You can strategically use these odors around your property by planting these crops near your garden and by the entrances to groundhog burrows. Commercially available repellents offer another option, and for best results, scent-based deterrents should be used alongside other preventive measures.
