"I used them for mosquito control Weather has a major impact on scheduling, so it was hard to set firm dates for service. Always showed up once they were scheduled. Treatments provided significant, but not total relief from mosquito problem. Price was good compared to other services. Techs were always pleasant and professional."

Pest Control FAQs, answered by experts

There are several ways to dry out flea eggs. Diatomaceous earth (DE) is a natural ingredient that can dry out fleas, but it’s messy to apply and can also cause respiratory issues for members of your household if inhaled. Salt is safer and easier to apply, so shake it liberally over affected areas. Boric acid is another way to get rid of fleas and other insects, but this, too, can cause respiratory issues and health problems if inhaled or ingested.

It’s an age-old and terrifying question: Can rats come through the toilet? The answer, unfortunately, is yes; however, it’s extremely rare. In the very unlikely case that this happens, it’s usually the result of rats from the sewer making their way into home plumbing pipes and up into the toilet. 

It takes a few weeks to get rid of roaches in the kitchen for a small infestation, as the cockroaches will need to take the bait back to their nest to infect the others. For larger infestation, you may need to schedule multiple professional treatments, which could take several weeks or up to 6 months to get rid of the roaches fully.

You don’t need heavy-duty chemicals to get rid of a bobcat. In fact, one of the most simple and effective methods of preventing bobcats from entering your property is by keeping your yard clear of overgrowth by trimming bushes and trees regularly. This eliminates potential hiding spots for a bobcat and makes them easier to spot in general.

Generally, spring is the best time to hire a pest control service, but it also depends on when you notice the infestation. Insect pest numbers are lower in spring before they hatch, making the extermination and prevention process more manageable as nests and eggs of future pests are eliminated. However, don’t hesitate to hire a pest control specialist when you spot signs of a problem.
