Our Mount Sinai Pest Control Team
Mount Sinai is a short drive east on Nesconset Highway, so it sits on our regular North Shore routes. Pest control supervisor Karl Lacalandra started as a mosquito and tick sprayer, and he oversees the technicians who treat harbor and trail-side yards here.

Meet the whole teamPest Control Across Mount Sinai and Suffolk County
We cover Mount Sinai and the 11766 ZIP code, from the harbor south past Route 25A toward Coram. That includes Crystal Brook Park, the streets off Pipe Stave Hollow Road and the newer homes on the former Davis Peach Farm.
Homes near Mount Sinai Harbor and Satterly Landing sit close to salt marsh, and mosquitoes rest in the shrubs nearby. Along the North Shore Rail Trail and the trails at Heritage Park, brushy edges hold ticks. In the hamlet’s few 18th century houses near the harbor, old framing draws carpenter ants and termites.
Mount Sinai Harbor covers 455 acres, mostly salt marsh, mudflats and open water, and mosquitoes breed along its wet edges. Much of the land south of North Country Road was farmland until the 1960s, and older homes there now let mice in through aging gaps. The North Shore Rail Trail begins at Crystal Brook Hollow Road, and its brushy edges hold ticks.

We offer same-day and next-day service in Mount Sinai and across Suffolk County. Call (631) 681-5581 and we’ll give you the first open time.
Why are mosquitoes so bad near Mount Sinai Harbor?
The harbor is 455 acres, mostly salt marsh, mudflats and open water. Mosquitoes breed in the marsh and in standing water in nearby yards, then rest in shady shrubs by day. Our tick and mosquito program treats those resting spots through the season, and we find breeding spots.
Do homes along the North Shore Rail Trail get more ticks?
They can. The trail runs about 10 miles from Crystal Brook Hollow Road east to Wading River, and its brushy edges hold ticks. Our tick and mosquito program treats the edge where your lawn meets the brush, not the whole lawn, through the season.
Do you cover Crystal Brook Park and the homes along Shore Road?
Yes. Crystal Brook Park, on the southwest side of the harbor, dates to 1892 and is part of our Mount Sinai coverage. So are the homes off Shore Road along the harbor. The inspection is free, and you get the price first.
How much does pest control cost in Mount Sinai?
It depends on the pest, the size of your home and whether you want a one-time treatment or ongoing service. The inspection and estimate are free, and you get the price before any work starts.
What pests are most common in Mount Sinai?
Mount Sinai Harbor covers 455 acres, mostly salt marsh, mudflats and open water, and mosquitoes breed along its wet edges. Much of the land south of North Country Road was farmland until the 1960s, and older homes there now let mice in through aging gaps.

We also treat ants, spiders, ticks, mosquitoes, wasps and rodents, and our wildlife division handles raccoons, squirrels and bats.
Do you guarantee pest control in Mount Sinai?
Yes. On our Quarterly plan, if covered pests come back between visits, we come back at no extra charge. Most one-time treatments carry a 60-day warranty: if the same pest comes back in the treated area, we retreat it free.
Are your treatments safe for kids and pets?
Yes. We use pet and family safe products. Your technician tells you if an area needs to stay clear and for how long.
