"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

Yes, it’s possible to have bed bugs and not find them because they hide in small spaces outside of mattresses, including baseboards, headboards, electrical outlets, clothing, and in crevices of walls. They can squeeze into spaces as small as the width of a credit card. Bed bugs can also live up to 400 days without feeding, making them resilient and hard to eradicate.

There are several possible reasons for a gnat infestation, and they vary based on the type of insect. One common reason is overwatering houseplants, which can create a moist environment that is attractive to fungus gnats. Another reason is leaving fruit out on the counter for too long, which can attract fruit flies. Drain flies are typically attracted by standing water and bacteria that are often the result of buildup or a clog in your drain or sewer line.

Roaches won’t sting your pets and don’t have venom like spiders do , but they present other dangers. Cockroaches are notorious carriers of diseases like salmonella and parasites like tapeworms. Because they’re so dirty, their bites (otherwise harmless) can also get infected. You don’t want your pets chasing and trying to eat cockroaches, or sleeping near a roach infestation. 

While bleach is an effective roach killer, we don’t recommend using bleach as a drain cleaner. Bleach can release toxic fumes from your drains. Applying this chemical could cause damage to the entire drain system over time. It's better to use homemade drain cleaners or cleaners that don't contain bleach.

One way to keep pests away is with good housekeeping. Keep ants away with a clean kitchen. They’re less likely to wander in looking to score some free food if there isn’t a mess to find. Wipe down counters, don’t leave dirty dishes around, and keep food in air-tight containers. 

Home and yard maintenance can also keep pests away. Seal windows, patch any holes or cracks, and put screens on the vents to prevent bugs, rodents, and other uninvited guests from coming in.
