Chesterbrook's Seasonal Barrier Treatment Team

Most treatments stay effective around 21 days, which is why seasonal programs schedule on that cycle.

Both — barrier spray handles adults while larvicide treats standing water we can't drain. 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.

Most Chesterbrook properties do well on a 21-day cycle through the warm season, adjusted for rainfall. We recommend a yard check after heavy rain, since new standing water shows up in unexpected places.
