Beach Haven, NJ's Seasonal Mosquito Barrier Treatment Team

Most barrier treatments remain effective for about 21 days, which is why seasonal programs schedule visits on that cycle.

Both — barrier spray handles adult mosquitoes while larvicide treats standing water we can't drain, addressing the full breeding cycle.

Barrier products are applied according to label guidelines for residential use — we'll flag any areas needing special handling.

Event treatment is common; we time the application so the barrier is at peak effectiveness for your specific date.

Standing water features require a different approach — larvicide — because barrier spray only affects adult mosquitoes, not developing larvae.

A three-week cycle is typical, though heavier rainfall seasons sometimes call for tighter scheduling. It also helps to check for any new containers holding water after storms, since a single overturned bucket can restart breeding within days.
