Millipedes in Staten Island
Staten Island has the most millipede problems in the city due to its wooded lots, the Greenbelt, lawns and extensive landscaping. Homes with full basements and ground-level garages frequently see hundreds of millipedes after heavy rains and during fall migrations. Homes bordering wooded lots and wetlands are hit hardest.
Every building in Staten Island is different, which is why professional millipede control starts with a careful inspection. A licensed pro identifies the species, locates entry points and harborage, and builds a plan that fits your home, apartment or business.
Millipedes are slow-moving, many-legged arthropods that live in damp soil, mulch and leaf litter, where they help break down decaying plant material. They are harmless to people and do not bite, but when conditions outside become too wet, too dry or too cold, they can move indoors in large numbers. Finding dozens of curled-up millipedes on a basement floor or garage every morning is a common and frustrating experience. In some years, especially after very wet weather, homeowners report hundreds of millipedes entering at once, piling up along door thresholds and basement walls.
Signs of Millipedes in Your Staten Island Home
- Numerous millipedes, often curled into tight coils, found on basement floors, garage slabs or ground-floor rooms each morning.
- Millipedes crawling on foundations, patios, walkways and door thresholds after heavy rain or during dry spells.
- Dead, dried millipedes accumulating along baseboards, door sweeps and basement window sills.
- A faint, unpleasant odor or small stains from defensive fluids released by crushed or disturbed millipedes.
- Large numbers of millipedes in mulch beds, compost piles, leaf litter or beneath stones near the foundation.
How Millipede Control Works in Staten Island
- 1
Inspection
A licensed technician examines mulch beds, leaf litter, drainage, gutters and the foundation to find where millipedes are breeding, then checks basements, garages and door thresholds to identify entry points.
- 2
Habitat Correction
The provider recommends thinning or pulling back mulch, clearing leaf litter, fixing drainage and gutter issues, and moving compost away from the house to shrink the millipede population outdoors. These changes provide lasting relief.

Perimeter Treatment
Targeted exterior treatments may be applied to foundation perimeters and harborage areas during invasion periods. This creates a barrier that helps stop millipedes before they reach doors and basement windows.

Exclusion
Door sweeps, weatherstripping, window well covers and foundation sealing close common entry points. Garage door seals and gaps around utility lines are also addressed. Sealing work is especially important before fall migrations.

Follow-Up
A follow-up visit checks whether indoor sightings have dropped and whether outdoor conditions have improved, with adjustments made for seasonal invasions after heavy rain. Seasonal perimeter service may be suggested for homes with repeated invasions.
Seasonal Activity in Staten Island
Millipede invasions in NYC typically occur in spring and fall. Mass movements are common in September and October, when millipedes migrate in search of overwintering sites, and after heavy rains in late summer that saturate soil. Hot, dry spells can also drive them toward the moisture found in basements and garages.
Staten Island has a distinctly suburban pest calendar. Spring brings termite swarms, carpenter ants, and wildlife raising young in attics and under decks. Summer increases ant, cricket, earwig, and outdoor pest activity, along with moles tunneling in lawns. Fall is the busiest time for mice, squirrels, and raccoons trying to get indoors before winter, and millipedes often wander into basements after rain. Winter pushes rodents deeper into walls, attics, and crawl spaces.
