"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

The number of treatments required to eliminate bed bugs varies depending on the severity of the infestation. Most cases require two to four treatments within a three- to six-week span. However, a small infestation might only need one inspection and one treatment visit. In contrast, severe cases or large homes may require an ongoing plan with quarterly, monthly, or semi-monthly visits from an exterminator for up to a year. To get rid of bed bugs as quickly as possible, it's best to investigate and treat them at the first sign of an issue.

Rats have a strong sense of smell and do not like the smell of bleach. However, pouring bleach in drains or toilets is not a good idea because it can cause dangerous chemical reactions and even damage your pipes. It’s best to have a professional plumber install a rat-blocker or non-return valve instead to keep critters from crawling up the toilet.

If a coyote approaches you, never run away, even if it goes against your natural instinct. Make yourself look big, shout loudly, and throw something in the coyote's direction. Be persistent and continue these scare tactics until they move away. Then, you should move away slowly, always facing the coyote.

Fogging keeps mosquitos away for an average of 72 hours. This is the length of time that a mosquito fogging machine will continue to operate at peak performance for pest control and protection. After the initial 72 hours, the fogger may still keep mosquitos away but will gradually decrease in effectiveness.

Yes, dryer sheets can help repel mice. The strong artificial fragrances found in many dryer sheets, such as citrus, floral, or lavender, are unpleasant to mice, which are very sensitive to smells. Many people report success using them to deter mice from areas like cars, drawers, vents, and cupboards. The scent can last for many days, making the space undesirable for rodents. However, dryer sheets may not be a foolproof solution on their own. For more effective protection against rodent infestations, it is best to combine them with other preventive measures like traps, repellent sprays, and proper storage practices.
