"Ken and his helper were amazing. Ken came out to recommend and quote light fixtures in our unfinished basement, connect a couple of Ring floodlights, and replace the doorbell transformer and install a new Ring doorbell at my residence. Ken's work is clean, fast, and reasonably priced! I would absolutely hire him again!"

Nest Installation FAQs, answered by experts

Cockroaches, ants, flies, bed bugs, and termites are common in business environments.

Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

The number of spiders considered normal in a house can vary significantly depending on geographic location, season, and the specific environment of the house. Generally, it's common for a home to have one or two spiders present at any time. If you consistently notice more than one spider in your home daily or you're dealing with potentially dangerous species, it's advisable to seek professional pest control services to address the issue.

While cockroaches can contaminate appliances and their contents, they won't cause damage. Cockroaches can spread bacteria like E. coli and salmonella, making it important to keep them out of places where food is stored, such as a refrigerator. When it comes to electronics, however, cockroaches could potentially damage internal electrical components. As the pests navigate inside a TV or console, they may touch high-voltage components that could short out your product. This damage could lead to costly repairs or require replacements.

Besides reptile sightings, look for droppings resembling small pellets. Shed skin left behind during growth is another clue. Unusual chirping or rustling sounds could also suggest an infestation. If unsure, consulting a professional can provide accurate identification and effective solutions for managing the situation. If proper pest prevention measures aren't taken, a lizard can live up to five years. And that's a long time to have an undesirable roommate.
