"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

Spiders are most active during the warm spring and summer months. During this time, most spiders emerge from their hiding places to lay eggs and hunt for food. However, each species of spider is different and some are more active than others. Stay vigilant for signs of spiders in your home once the weather begins to warm.

While not common, bird’s nests can cause problems to your property in some cases. 

  • Block vents for your dryer, stove, and fans, creating a fire hazard

  • Clog gutters and drains, leading to roof and siding damage

  • Damage solar panels

  • Wiring issues if the nest is on or near a light fixture

The most effective natural roach repellent is Borax with its key ingredient of boric acid and diatomaceous earth. But some homeowners may not feel like these are “natural” enough, especially since you can’t use Borax around curious pets or toddlers.

On the other hand, studies have shown that oregano oil mixtures have some of the best repellent effects, and other research indicates that catnip oil, peppermint oil, and citrus oils have notable effects on keeping roaches away. Rosemary oil has been shown to be the most effective natural oil for killing cockroaches outright.

Squash bugs don’t bite humans or pets. Their piercing-sucking mouthparts are designed specifically for feeding on plants, not people. While they can be a major nuisance in the garden, they pose no direct physical threat to you, and you don’t need to worry about bites, stings, or venom from these pests.

Aside from a warm, cozy place to curl up, you might wonder what attracts mice to your home. Several items attract mice, including: Birdseed Pet food Water Cereal and whole grains Food scraps from the composting bin Open trash cans High-fat and high-sugar foods Unused cars—they make great homes for chilly mice Insulation in the attic Clutter Brush from your yard, including leaves, sticks, wood, and shrubs (so mice can make nests) Overgrown trees or bushes—mice love to leap from branches onto the roof Indoor nesting materials, including cloth, paper, tissues, and toilet paper Tiny cracks in the siding or foundation
