Barrier treatments last for about 21 days at a time. Regular reapplication is what makes it possible for mosquito treatments to work all season. A typical season will require between seven and nine treatments.
Mosquito treatments last for a while, but not forever. That’s why they need to be reapplied. Even still, if you’re planning for the warm season or you’re trying to figure out how much treatment will cost, it helps to know how many treatments your Long Island home will need in a season.
On Long Island, mosquito season generally opens sometime in spring, often May, and runs until the first hard frost in fall, which can land in October or even later in a mild year. That's roughly five to six months of active mosquito pressure. That’s why you can expect about seven to nine treatments in a typical year. Long, warm seasons might need a little more, and cooler ones might require a little less.
Each barrier treatment is built to keep working for about three weeks at a time. After that period, the treatment starts to break down in the environment and it needs to be refreshed. New applications keep the barrier continuous instead of letting it lapse.
Worth noting separately: if you have a one-time special event coming up, you can book a one-off treatment. It’s the kind that you would add before a party or wedding and does not require ongoing planning. It won’t protect you for the season, but it can give you extra coverage on those days you really need it.
