"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

Mosquito fogging should be done every two days during the first week of treatment. This level of frequency helps to interrupt the mosquito breeding cycle and prevent them from laying eggs in your yard. After the first week, mosquito fogging can be reduced to a schedule of once a week.

Having a few spiders in your home is okay and in many cases can be beneficial. Spiders can help reduce the presence of other pests, such as flying gnats and mosquitos. If you fear that you have a venomous spider living in your house or a large infestation, you should hire a spider exterminator to help you remove it.

Yes, exterminators are a type of pest control professional that is qualified to remove wasps safely and effectively. Exterminators will inspect the wasp problem, administer professional-grade treatments, and apply preventative measures to avoid a future infestation. Consult a local exterminator about your wasp problem as soon as you identify it.

Whether a one-time spray treatment to control mosquitoes is enough depends on multiple factors. Often, you’ll notice a big difference after one application. However, mosquitoes are likely to return if you don't reduce attractive standing water habitats. This usually takes four to eight weeks if it’s still prime mosquito season.

The costs range from $300 to $2,500, depending on the severity of the infestation and the treatment method (heat, chemicals, or fumigation).
