7 Pest Control Tips for First-Time Homeowners on Long Island, NY

Becoming a homeowner on Long Island is an exciting milestone, and it comes with a new responsibility: keeping pests out of a house that's now entirely yours to protect. Most pest problems in a first home come down to the same handful of gaps: unsealed entry points, an unmaintained yard, and no plan in place before something shows up. Whether you've just moved into a historic home in Huntington or a newly built one in Islip, here are seven pest control habits worth building into your first year of homeownership, plus a season-by-season calendar so you know what to watch for and when.

1. Seal Off Entry Points

Sealing entry points is the single most effective pest control step a new homeowner can take, because it keeps pests out instead of dealing with them once they're inside. Cornell Cooperative Extension of Warren County notes that an adult mouse can squeeze through an opening as small as 3/8 of an inch, about the width of a pencil. Cornell Cooperative Extension of Dutchess County adds that pests can come in through a crack, an open door, a torn screen, or a gap in siding, and the larger the opening, the larger the pest you can end up hosting.

2. Maintain Your Yard

Maintaining your yard keeps pests from building up right next to your foundation, where they're one small gap away from getting inside. Overgrown grass, dense shrubs, and leaf piles give insects and rodents cover close to the house. Cornell Cooperative Extension of Nassau County also notes that shrubs touching the house or blocking foundation vents increase moisture around the foundation, which encourages termites.

• Trim trees and shrubs: cut back branches and plants touching the house, since they act as a bridge for rodents and insects and trap moisture against the siding.
• Rake leaves away from the foundation: leaf litter shelters insects and holds moisture next to the house.
• Keep wood off the ground and away from the house: Cornell Cooperative Extension of Nassau County notes that wood debris in the yard can support a termite colony until it grows large enough to attack the home itself.
• Dump standing water weekly: Cornell's New York State IPM Program notes that the most common mosquito in New York can go from egg to adult in about 7 days, and a bottle cap of water is enough to breed in.
• Point downspouts away from the house: water pooling at the foundation draws termites and other moisture-loving pests.

Your neighborhood shapes which of these matters most. Homes near the water need extra attention to standing water and mosquitoes, while homes near wooded areas, like parts of Massapequa, should put rodent prevention near the top of the list.

3. Keep Food Sealed

Keeping food sealed takes away the main reason ants, cockroaches, and mice come inside once they find a way in. Cornell's New York State IPM Program notes that rodents will eat packaged food, spills in hard-to-clean areas, pet food left in bowls, and even pet waste, so the goal is to leave nothing within reach.

• Use airtight containers: store cereal, flour, rice, and pet food in glass or hard plastic containers with tight-fitting lids.
• Clean up crumbs and spills right away: wipe counters and sweep floors regularly, including behind the stove and refrigerator and under the sink.
• Pick up pet food bowls: don't leave food out overnight.
• Keep trash bins sealed: loose lids invite flies, rodents, and raccoons, especially in warmer months.
• Fix leaks: dripping faucets and pipes under the sink give pests the water they need.

4. Watch for Termites

Watching for termites matters most in your first year, because termites can be active for years before a homeowner notices anything. Cornell Cooperative Extension of Nassau County explains that the eastern subterranean termite, the only termite species on Long Island, lives in the soil and its workers never come out in the open. The extension office adds that many homes on Long Island are currently affected by termite colonies, and it usually takes several years for termites to cause extensive damage.

Termites or flying ants?

Termites and flying ants are easy to confuse, because both swarm in spring. Cornell Cooperative Extension of Nassau County describes three clear differences:

Cornell Cooperative Extension of Nassau County recommends hiring a certified professional with termite experience for an inspection, since many control methods can only be applied by applicators licensed by the New York State Department of Environmental Conservation. A professional termite inspection in your first year gives you a baseline, especially in an older home.

5. Plan for Seasonal Pests

Planning for seasonal pests means knowing which pests show up when, so you can prevent problems a few weeks before they start. Spring and summer bring termite swarms, ants, mosquitoes, wasps, and ticks, while fall and winter push rodents indoors looking for warmth. Cornell's New York State IPM Program notes that white-footed mice and deer mice, which live mostly outdoors, enter buildings from fall through spring.

• Mosquitoes: dump standing water weekly from gutters, birdbaths, toys, and tarps. The New York State Department of Health also recommends getting rid of discarded tires and keeping window screens free of tears. For persistent problems, mosquito control treatment targets both adults and larvae.
• Ticks: the New York State Department of Health notes that ticks are active whenever the weather stays above freezing, usually April through November, and recommends removing leaf litter, brush, and weeds at the edge of the lawn.
• Rodents: inspect your attic, basement, and garage once temperatures drop, and consider rodent control if you notice droppings, gnaw marks, or scratching in the walls.
• Spiders: clear webs and clutter from corners, basements, and garages, and seal gaps around doors and windows so spiders and the insects they feed on stay outside.

6. Check for Bed Bugs at Move-In

Checking for bed bugs at move-in is worth a few minutes, because bed bugs are much easier to deal with before they spread through a home. The NYC Department of Housing Preservation and Development notes that prevention, early detection, and rapid treatment are the surest ways to keep bed bugs from spreading, and that holds true for a first home just as much as an apartment.

• Inspect furniture that came with the house: check the seams of mattresses, box springs, and upholstered furniture for dark spots, shed skins, or live bugs.
• Inspect second-hand furniture before it comes inside: look closely at seams, joints, and cushions.
• Wash second-hand bedding and fabrics right away: use hot water, then dry on high heat.

7. Invest in Professional Pest Control

Investing in professional pest control gives a first-time homeowner a trained second set of eyes on problems that are easy to miss, like termite activity inside walls or a rodent entry point under the deck. DIY habits handle a lot, but they won't catch what's already established out of sight. Here's how each approach compares:
