Mosquito & Tick Monthly Reports

June marks the start of peak mosquito season across Long Island. Warming temperatures, frequent spring rain events, and the transition from tick nymph to adult season create elevated pressure countywide. Homeowners with waterfront, wooded, or shaded properties should assess treatment options early in the month.

July is peak mosquito season on Long Island. High heat, humidity, and frequent afternoon thunderstorms create near-ideal breeding conditions. Mosquito populations reach seasonal maximums during the third and fourth weeks. Tick activity remains elevated with adult deer ticks and lone star ticks active across both counties.

August begins at or near peak mosquito activity and transitions toward late-season pressure by month's end. The first half of August remains a high-risk period — particularly following rain events. Tick activity is sustained through the entire month, with deer tick adults increasing as summer ends.

September marks the transition from peak summer mosquito season to elevated fall tick season. Mosquito pressure declines steadily as temperatures cool, but deer tick adult activity increases significantly. September is often the most overlooked month for pest control — homeowners with wooded properties remain at significant tick risk through the entire fall.
