No, a single barrier treatment stays effective for about 21 days. Mosquito season in Southern New Hampshire runs roughly from May through September. One treatment will give you a few great weeks, but the population rebuilds once the product breaks down.
Many people wonder why mosquito treatment has to be continually reapplied. They wonder: why isn’t it possible to just treat once, and enjoy the rest of the year?
It’s a reasonable hope, but not one that holds up to scrutiny due to the ecological science that makes mosquito control work. Mosquito barrier treatments bind to vegetation and surfaces where mosquitoes rest. When mosquitoes stop to rest in the hot and dry parts of the day, they touch the treated surfaces, and are knocked down. It works really well on a population level, which is why you can see an up to 90% reduction in the mosquito population while the treatment is working.
Sun and rain break down the treatment with time, usually taking about three weeks. Once this happens, the surviving mosquitoes can repopulate quickly. A single female can lay 100–200 eggs at a time, and those eggs develop into biting adults in 7–14 days. In short, mosquitoes can bounce back quickly.
Treatment knocks them down when they land on treated surfaces, but once the product breaks down, nothing remains to stop the next generation. Add to this the fact that mosquitoes can also fly in from neighboring properties. Even if you managed to eliminate every single mosquito within your property line, more could come in from outside and restart the problem anew.
Seasonal programs work because they are consistent. Treatment goes up, it works for a few weeks, it starts to wear off, and a technician comes back to reapply it. Mosquitoes never have a chance to recover in between.
