Dover Plains's Seasonal Barrier Treatment Team

Residual barrier typically holds about three weeks before new activity requires re-treatment.

A complete job includes both perimeter spray and treatment of any breeding sources found. Effectiveness depends on more than just your own property, which is why we ask about neighboring water sources during the initial call.

Barrier product follows label guidelines for residential use — we'll note anything needing special handling.

Yes — we schedule timing a day or two before the event for maximum effect on the actual date.

Ponds usually need larvicide rather than barrier spray, since spray doesn't reach larvae developing in water. A few landscaping adjustments between visits can meaningfully extend how long a barrier treatment stays effective.

A three-week cycle is typical, though heavier rain sometimes calls for tighter scheduling. It also helps to check for new containers holding water after storms, since a single overturned bucket restarts breeding fast.
