The team's outside perimeter treatments erect a barrier against unwanted guests through an EPA-approved spray that won't harm the lawn's human inhabitants, plants, or those insects that provide valuable services to the ecosystem. Inside perimeter treatments block off entrance routes with microencapsulation chemistry technology, effectively plugging up tunnels and jamming the control systems of bug subways.

When dealing with mosquitoes, techs defeat the bloodsuckers with a multistep attack, spraying yards with six treatments. They pay particular attention to areas with standing water, which mosquitoes breed in, treating them with products designed to kill larvae. The team then focuses on places where adult mosquitoes rest during hot days, including trees and shrubs, and shaded areas under decks and eaves.
