F.A.Q.

How long does a mosquito treatment last?

A professional barrier treatment usually works 2–3 weeks at a time. Treatments are scheduled on a recurring basis every three weeks throughout the season so mosquito populations never have a chance to recover. 

You may be wondering if one treatment is enough to solve your mosquito problem for the summer. The honest answer is that it probably is not, and that is partly because of the nature of mosquito treatment and partly because of mosquito biology.

In Boston Metro South, mosquitoes are usually active from April to October. When mosquito treatment is applied, it goes on vegetation and in shaded zones. This targets mosquitoes where they rest during the day. The product bonds to leaf surfaces and controls mosquitoes on contact as they land on treated areas. The residual effect is what gives each application its two-to-three-week window.

But even though the product is tough enough to work outdoors, sun and rain exposure will break it down over the course of weeks. When the treatment loses effectiveness, it can no longer provide the 85-90% reduction in the mosquito population that makes it worthwhile. Also important to remember is that mosquitoes only need about 7-10 days to hatch the next generation, so even short treatment lapses give mosquitoes a chance to regroup and should be avoided if possible.

If you are looking to further improve the effectiveness of mosquito treatments, the best thing you can do is remove standing water on your property. Mosquitoes only need a tiny amount of water to breed, and a forgotten plant saucer or clogged gutter can easily become a mosquito hatchery. A little outdoor home maintenance goes a long way here.
