Mosquito barrier treatments target spots where mosquitoes rest during the hot, dry parts of the day. When mosquitoes rest on those surfaces, they’re knocked down. This works for about three weeks at a time.
The term "barrier spray" is not one that tends to come up in everyday conversation. And because it describes both where the treatment goes and how it works, it’s worth breaking down further what it means.
The "barrier" part refers to the targeted surfaces. Adult mosquitoes don't spend their day out in the open. They rest in cool, shaded, humid spots. In fact, if it’s mid-day right now, you’ll probably find mosquitoes in places like the undersides of leaves or tall grass. Barrier treatments go on these areas, which creates a treated zone around the vegetation where mosquitoes spend most of their time. It’s not a fog that lingers over the lawn.
The "spray" does two jobs. On application, it knocks down the mosquitoes that are present in the treated areas right then, giving an immediate reduction. What’s left behind bonds to the foliage. Mosquitoes that land on those treated surfaces, even a week or two later, are knocked down. This is why it works for about three weeks at a time.
Barriers break down with enough time, which is why they're refreshed every 3 weeks. For households that prefer it, there's also a plant-based natural version of the barrier treatment made with essential oils. It works about as well as the traditional treatment, but needs to be reapplied more often (every 2 weeks rather than every 3 weeks).
