Long Island's temperate maritime climate means we deal with a rotating cast of pests throughout the year. Understanding the seasonal patterns helps you stay ahead of problems instead of reacting to them.
Ticks: Deer ticks become active as soon as ground temperatures hit 45°F. On Long Island, this is typically mid-March. This is the most important time to start perimeter treatments.
Carpenter bees: These large, wood-boring bees emerge in April and start drilling into untreated wood — eaves, decks, fascia boards, and pergolas. Males hover aggressively but can't sting. Females can sting but rarely do.
Paper wasps: Queens emerge from overwintering and begin building new nests. Early removal in April prevents large colonies later.
Mosquitoes: Asian tiger mosquitoes and house mosquitoes become active in May as standing water warms. This is when to begin barrier treatments.
Lone Star ticks: More aggressive than deer ticks, Lone Star ticks emerge in late April and peak in June. They're found in brushy areas and can transmit Alpha-gal syndrome.
Black flies: Common near streams and flowing water on the North Shore and in wooded Suffolk County areas. Peak activity is May through mid-June.
Yellow jackets: Colonies reach peak size and aggression in late summer. This is when most stinging incidents occur — at barbecues, near pools, and around garbage cans.
Mosquitoes: Maximum population. Consistent, regular treatments are critical during this peak.
Stable flies: A painful coastal pest common on South Shore beaches and waterfront properties.
Yellow jackets: Colonies become desperate as food sources dwindle. September is the most dangerous month for yellow jacket stings on Long Island.
Cluster flies: Begin seeking entry into homes for overwintering. They're attracted to south- and west-facing walls warmed by afternoon sun.
Ticks: A second peak of deer tick activity occurs in October-November as adult ticks seek hosts before winter.
Ticks: Deer ticks remain active in mild winters whenever temperatures exceed 40°F. Don't assume you're safe just because it's December.
Planning: This is the ideal time to schedule a property assessment, install deer fencing, clear brush, and plan your spring treatment schedule.
