Mosquitoes can only fly short distances as adults before they must seek shelter and rest. By treating the ornamental trees and shrubs of customers’ properties, we effectively protect their landscape from adult mosquitoes seeking shelter in treated shrubs during the day. No service can offer 100% protection from every mosquito, as it’s always a possibility that a mosquito from a neighboring property could wander into your yard and bite you before resting on the treated foliage. However, you’ll find that the presence of mosquitoes will be significantly reduced once your yard is treated with our Mosquito Defense.
