Millis-Clicquot'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. A single missed water source nearby can shorten how long a barrier treatment stays effective, so we always ask about the whole surrounding area, not just the yard itself.

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.

Water features need a different approach — larvicide — because spray only affects adults, not larvae. A few landscaping adjustments between visits can meaningfully extend how long a barrier treatment stays effective.

Most Millis-Clicquot 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.
