"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

Adult fleas can live from a few days to about two weeks without a host. If pets are not available, fleas may feed on rodents or people. While adult fleas need a blood source to survive, flea pupae can lie dormant for up to a year in optimal conditions. Therefore, cleaning and treating the infested area is essential to prevent pupae from surviving and hatching later.

Roaches have a strong sense of smell and are repelled by a variety of potent aromas. Scents that can help deter them include citrus (such as lemon and orange), herbs like peppermint, mint, basil, thyme, and oregano, spices like bay leaves, cinnamon, clove, and garlic, as well as lavender, eucalyptus, citronella, tea tree oil, and vinegar.

You can use these scents in several ways to create an unwelcoming environment for roaches:

  • Plants: Place mint or lavender plants in your home or garden.

  • Powders and Leaves: Sprinkle garlic powder or place crushed bay leaves and citrus peels in high-risk areas like kitchens, bathrooms, and entry points.

  • Sprays: Create a diluted solution with scents like lemon or vinegar to spray in your home. These can also be used in cleaning products or as room fresheners.

  • Essential Oils: While essential oils of these scents can be used, be cautious as they can be toxic to pets if inhaled.

It is important to note that while these smells can help keep roaches away, they typically do not kill them and may not be enough to drive out an existing infestation entirely. For best results, combine these scent-based deterrents with regular cleaning. Be sure to clean up all food spills, crumbs, and dirty dishes promptly, and keep trash cans covered with a tight-fitting lid to remove potential food sources.

The time of day that most snakes are active is at night. This is when they prefer to hunt since they can do so under the cover of darkness, out of sight of predators and the prey they stalk. However, some snake species prefer very hot temperatures and are strictly active during the day.

Tree sap is not usually dangerous to humans or pets. But some trees do produce dangerous sap. Notably, ash, birch, cedar and similar saps can irritate the skin but aren’t dangerous. Sap from trees like the Brazilwood, Mahogany, Milky Mangrove or well-named Poison Walnut can be corrosive, cause nausea, or trigger those with asthma. But for most backyard trees, protective equipment like a sturdy pair of gloves should be fine.

Dawn detergent does much more than clean germs on your dishes. It can also help remove flea eggs from your pet. Give your pet a bath using a few squirts of Dawn in warm water—be sure to keep it away from their eyes—to wash away those flea eggs. Note that Dawn doesn’t actually kill the eggs, nor can it help you with any eggs that have already fallen off your pet and taken up residence in your household, though.
