"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

Spider egg sacs are meant to last, so you can't crush them. One of the best ways to deal with them is to vacuum them up and then quickly dispose of your debris in the trash so the egg sacs leave your property permanently. Egg sacs surrounded by little spiderlings means that it has already hatched, but you may be able to catch many of these with a vacuum cleaner, too.

Across most of the United States, the fall season sees rats at their prime activity levels. As temperatures drop, rats become more active, spurred by the weather shift to seek shelter as winter approaches. During this time, their curiosity and energy peak, driving them to explore what your home and its surroundings might offer.

First, you’ll start noticing fewer flying termites in the air. Second, you’ll see fewer ground-based termites near the entrances to their colony, and eventually none at all. Third, if you have access to part of the nest like mud tubes, you can scour away a section and watch it. If the tubes don’t get repaired, the nest is probably doomed. Again, it can take several weeks for termites to fully go away, depending on the type of treatment.

A temperature of 119 degrees Fahrenheit will kill bed bugs and their eggs within 90 minutes. No temperature kills them instantly, but if exposed to high temperatures over extended periods, bed bugs will be killed off. Bed bug eggs must be exposed to the same temperature for 90 minutes to reach 100% mortality.

If your house is full of things that attract spiders, you’re more likely to have a population explosion. When you have lots of cracks leading to warm, secure spots in your home, why wouldn’t they want to come in? Especially if your home has plenty of other meal-ticket insects, like flies, roaches, and fleas. Sealing up obvious cracks and gaps and keeping your house bug-free makes it a less appealing place for spiders.
