Why do I still have mosquitoes after spraying?

The product we use will eliminate any mosquito that it comes in contact with. There may be more mosquitoes in the area that the product has not come in contact with, and they may fly back onto your property even after we treated. Our spraying does not prevent mosquitoes –  it only kills mosquitoes that are present during spraying. We welcome you to call again if the problem persists and we will re-treat the area when we are next in your town.
