The lanternfly may look like a colorful insect, but in New York, it has become a reason for destruction. These bugs have now spread across all five boroughs, feeding on over 70 species of plants, eventually making them weak.
New Castle’s landscape creates a distinctive mix of conditions for pest activity, particularly around homes and businesses near wooded areas, wetlands, ponds, and waterways. Much of the town retains a natural, forested character, with steeply sloped terrain and extensive open space that can provide habitat for rodents, insects, ticks, and other wildlife. The Saw Mill River and Kisco River, along with their tributaries, add moisture and vegetation corridors that can influence seasonal pest activity. New Castle is also closely connected to the Croton River watershed, with roughly 63% of the town located within the watershed that contributes to New York City’s water supply. In neighborhoods around Chappaqua and Millwood, wooded lots, mature landscaping, stone walls, older foundations, and properties bordering natural areas can create convenient pathways or harborage for pests. When temperatures drop or conditions change, rodents and insects may move from these outdoor environments into basements, crawl spaces, garages, kitchens, and other protected areas.
Mice and rats can take advantage of gaps around foundations, garages, utility penetrations, attics, and other entry points. New Castle’s wooded lots and natural areas can bring rodents closer to structures, particularly where buildings offer food, shelter, or accessible entry points. Our rodent control focuses on identifying access points, addressing activity, and reducing conditions that encourage repeat infestations.
Cockroaches can become especially problematic in kitchens, restaurants, commercial buildings, and areas with moisture or food access. A hidden infestation may extend beyond the locations where roaches are initially spotted. Our team looks for contributing conditions and develops a targeted treatment strategy designed to reach active harborages and interrupt the infestation.
Ant activity can increase around properties surrounded by lawns, trees, gardens, and wooded areas. In New Castle, the combination of suburban landscapes and natural habitats can create plenty of opportunities for ants to establish colonies outdoors before entering buildings. We target active trails and nesting areas while addressing the conditions that attract ants indoors.
Bed bugs can affect homes in Chappaqua and Millwood, apartments, rentals, hotels, and offices. Their ability to hide in mattresses, furniture, cracks, baseboards, and wall junctions makes early detection important. Our bed bug control process examines affected and adjacent rooms to identify potential spread and develop a treatment plan suited to the property, helping address activity before it becomes more difficult to manage.
