"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

If you’re wondering whether pest control services are safe, rest assured that they are if you hire a licensed and experienced exterminator. Professionals are trained to use EPA-approved products in controlled amounts and apply them in targeted areas to minimize exposure to people and pets. Plus, many modern pest control methods are designed to be low-risk while still effectively eliminating pests like scorpions. If you have concerns about chemicals, ask your exterminator about eco-friendly or integrated pest management (IPM) options, which focus on prevention and minimal pesticide use.

Neither the black widow nor the brown recluse are deadly spiders, and North America has no deadly species. However, other places in the world do, including Australia, which is home to the funnel web spider, considered the world’s deadliest spider. However, Australia has not reported deaths from a funnel web spider bite over the past few decades after developing an antivenom.

Common signs of a flea infestation include pets scratching or grooming excessively, itching and irritation affecting both pets and people, and visible flea bites or red spots on the skin. You might also see live fleas on your pets or find dark specks in their fur, known as 'flea dirt,' which is flea feces.

The best termite treatment depends on your specific infestation, home, and budget. According to the Environmental Protection Agency (EPA), the most common professional treatments are soil-applied barrier treatments, like liquid termiticides, and termite baits. Bait stations are placed in the soil and work by moving poison back into the colony to kill the queen. For infestations that haven't fully taken root, barriers and targeted termiticides are often the most effective options. Additionally, preventative measures such as moisture removal and installing physical barriers to protect vulnerable wood are important, particularly during construction or remodeling. It is best to work with a termite professional to determine the right treatment for your situation.

It may be better to have a mouse in your house than a rat. Rats are larger, more aggressive, and more difficult to eradicate once settled. One rat can cause more damage than one mouse. However, both animals pose a danger in that they can spread bacteria and contaminate food, so you’ll want to contact an exterminator as soon as you detect an infestation of either animal.
