Mosquitoes FAQ


  • How do I get rid of mosquitoes?

    Mosquitoes can be hard to control as they winged pests with the ability to fly around. Managing a mosquito problem indoors can be even more challenging. The use of harsh chemicals should be controlled in an indoor environment.

    However, the first step to get rid of mosquitoes at home is to prevent one from entering. Installing window and door screens is a good idea to keep mosquitoes out. Next, good housekeeping practices can also reduce any potential mosquito breeding. This includes removing any stagnant water in containers to prevent mosquitoes from laying eggs. Lastly, use larvicides to treat drains, pipes and water that are not used for consumption.
