"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.

"I had a fantastic experience with Milltown Pest Control! They came out quickly and treated a ground hornets nest in my horse paddock. They assured me that all the products used were animal safe and would bring no harm to my horses. They fixed my problem quickly and were extremely friendly and easy to work with. Would highly recommend this company to anyone, especially if you have animals and want to be sure they are safe."

"Have a terrible mole infestation in my front yard, contacted Brian and he was here the next day, he arrived two days later to start the job, he was very down to earth ( no pun intended) and very professional. I will be recommending him whenever I get the chance Kevin H"

Pest Control FAQs, answered by experts

No, mothballs do not keep bats away. Not only are mothballs completely ineffective when repelling or removing bats, but using them could be illegal, depending on where you live. Remember, bats are federally protected, and it's illegal to use chemicals during the removal process, and mothballs tend to fall into this category.

Spiders have lots of scent-sensitive hairs on their legs. Scented oils they aren’t fans of can act as a natural spider repellent to help keep their populations at bay when you rub them around your home’s entry points. Studies suggest mint and chestnut oils are two scents that spiders hate.

A rodent infestation often has a distinctive, unpleasant smell. The most common odor is a strong, musky scent, similar to stale ammonia, which comes from mouse urine. As the infestation grows, the smell can become more intense. You might also notice a foul, decomposing odor if mice or rats die inside the walls or hidden areas. This combination of smells is a clear sign of a rodent problem and should prompt immediate action to address the infestation.

You can remove a wasp nest yourself, but it isn’t a good idea. Although it looks easy enough to hit down a nest with a broom, wasps may be inside or around the nest and are known for getting aggressive when their nest is threatened. If you follow our guidelines for removing wasps nests with pesticide spray, insecticidal dust, water and dish soap, or boiling water, you may be able to safely tackle the problem.

Ticks are most commonly found behind (or even inside) ears, behind knees, in belly buttons, in the hair, and in your underarms. If you find a tick on your body or on your pet, use a pair of clean tweezers to grab the tick as close to the surface of your skin as possible. If you simply yank or twist it, you can leave the tick’s mouth parts lodged in your skin and will need to remove those carefully with the tweezers. 

Once you have removed the tick, flush it down the toilet and wash your skin with rubbing alcohol or soap and water. Know the signs of lyme disease such as fever, chills, headache, muscle aches, and a rash.
