What are the most common pests in Bergen County, NJ?
The most common pests in Bergen County, NJ are mice and rats, ants (especially carpenter ants), cockroaches, eastern subterranean termites, bed bugs, yellowjackets and wasps, mosquitoes and ticks, and wildlife such as squirrels, raccoons and bats. Most follow the seasons: ants, termites and stinging insects peak from spring through late summer, while mice and rats push indoors in fall and winter. Silver Bullet Pest Control is based in Garfield and handles all of them across Bergen County — call or text 973-510-2585 for a free quote.
The most common pests in Bergen County homes
These three account for a big share of the calls we get from Bergen County homeowners:
Mice and rats
- Droppings in cabinets, drawers and the garage
- Scratching in walls or ceilings at night
- Chewed food packaging
Mice move indoors as nights get cold, often through gaps where pipes, wires and the gas line enter the house. Rats show up more near dumpsters, older sewers, brooks and the Hackensack and Passaic riverbanks.
Ants
- Large black ants indoors in spring
- Sawdust-like piles near windows or decks
- Trails of tiny ants after rain
Bergen's tree-lined streets and older wood-frame homes are ideal for carpenter ants, which nest in damp wood. Odorous house ants and pavement ants are the small ones that trail across kitchen counters.
Termites
- Winged swarmers near windows in spring
- Mud tubes on foundation walls
- Wood that sounds hollow
Eastern subterranean termites are common throughout North Jersey. They live in the soil and reach the house through mud tubes, so damage often goes unnoticed for years.
Bergen County pest calendar: what shows up when
| Season | Most active pests | What to do now |
|---|---|---|
| Early spring (Mar–Apr) | Termite and ant swarmers, carpenter ants waking up, stink bugs leaving walls | Catch a swarmer and get it identified; check foundation for mud tubes |
| Late spring (May–Jun) | Carpenter ants, pavement ants, ticks, first mosquitoes, wasps starting nests | Trim branches off the house; dump standing water; check for ticks after yard work |
| Summer (Jul–Aug) | Yellowjackets, hornets, mosquitoes, fleas, fruit flies, roaches outdoors | Watch for nests in eaves, sheds and the ground; keep screens tight |
| Fall (Sep–Nov) | Mice and rats moving in, stink bugs and lanternflies, squirrels in attics, peak yellowjacket nests | Seal gaps before it gets cold; check the attic and garage for droppings |
| Winter (Dec–Feb) | Mice, rats, German cockroaches, wildlife in attics, bed bugs (any time) | Watch for droppings and noises; large ants indoors in winter mean a nest inside |
Roaches and bed bugs live indoors, so they don't really follow a season — they can show up any month of the year.
Mice and rats in Bergen County
Rodents are the number-one cold-weather pest in Bergen County. A mouse can fit through a gap about the size of a dime, and most homes have several: around the gas line, under garage doors, where the siding meets the foundation, and behind dryer vents.
- Signs: small dark droppings, a musky smell, chewed packaging, and scratching in the ceiling or walls at night.
- Prevention: store pet food and birdseed in sealed bins, keep firewood away from the house, and seal gaps with materials mice can't chew through — not foam alone.
- Professional help: trapping removes the mice you have; exclusion stops new ones. Our mouse service includes 90 days of coverage with unlimited free service calls in that time.

Insects: ants, roaches, bed bugs, stinging insects and mosquitoes
Cockroaches
German cockroaches spread between units in apartment buildings and two-family homes. Big oriental and American roaches (“water bugs”) come up from basements and drains. Our roach method is gel bait plus an insect growth regulator and a follow-up visit, with a 90-day warranty.
Bed bugs
They travel in luggage, used furniture and between apartments. Look for small rust-colored spots on mattress seams. We offer bed bug heat treatment.
Wasps, hornets, yellowjackets
Nests peak in late summer. Yellowjackets often nest in the ground or in wall voids. Honey bees are relocated with a local beekeeper, not exterminated.
Mosquitoes and ticks
Wooded lots, wetlands and the Meadowlands edge keep them busy all summer. Mosquito treatment starts from $95 plus tax.
Read cockroach control, bed bug treatment and mosquito control for details.
Wildlife: squirrels, raccoons and bats
Bergen County's mature trees and older homes give wildlife easy access to attics and chimneys. Squirrels chew through soffits and roof vents, raccoons tear open roof edges, and bats slip into gaps under shingles and flashing.
- Squirrels: scurrying in the attic in early morning and late afternoon.
- Raccoons: heavy thumping at night, torn vents, droppings on the roof.
- Bats: dark smudges and droppings near a gap, bats seen at dusk. In New Jersey, bat exclusion isn't allowed from May 1 to July 31 while pups can't fly yet.
We're licensed by the NJ Division of Fish and Wildlife for wildlife work, and we handle the cleanup too — odor control, HEPA cleanup and attic insulation removal and replacement. See wildlife removal and licensed bat exclusion.
How Bergen County housing shapes your pest problems
Bergen County has a little of everything, and the house you live in changes the pests you're likely to see:
- Older Cape Cods, colonials and split-levels across towns like Fair Lawn, Paramus, Teaneck and Bergenfield — mature trees, wood siding and finished basements mean carpenter ants, termites, mice and squirrels.
- Two-family homes and tight lots in south Bergen — Garfield, Lodi, Lyndhurst, Hasbrouck Heights and nearby towns. Mice and roaches can move between units through shared walls and pipes.
- High-rise and garden apartment buildings along the Hudson in Fort Lee and Edgewater and in Hackensack — roaches and bed bugs are building-wide problems that work best treated unit by unit, with the landlord coordinating.
- Homes near water and open land — along the Hackensack, Passaic and Saddle rivers, the Meadowlands and wooded parks — see more mosquitoes, ticks, rats and wildlife.
- Businesses along Route 4, Route 17 and Route 46 — restaurants, food stores and warehouses deal with rodents, roaches and flies year-round. See commercial pest control.
Tips for effective pest management in Bergen County
Seal the outside first
Close gaps around pipes, wires, vents and garage doors before fall. It's the single best step against mice and many insects.
Fix moisture
Gutters that overflow, leaky outdoor faucets and damp basements draw carpenter ants, termites, roaches and centipedes.
Cut back contact points
Keep branches, shrubs and mulch away from siding, and firewood off the ground and away from the house.
Store food and trash tight
Sealed containers indoors, lidded bins outside. Rinse recycling. Don't leave pet food out overnight.
Dump standing water weekly
Buckets, saucers, kiddie pools and clogged gutters breed mosquitoes in about a week in summer.
Identify before you treat
A photo and a correct ID save money — the wrong product for the wrong pest is wasted, and some sprays make ants and roaches worse.
DIY or professional pest control?
| Situation | Usually DIY | Call a professional |
|---|---|---|
| A few ants in summer | Wipe trails, fix leaks, use bait | Carpenter ants, ants in winter, ants that keep coming back |
| One mouse sighting | Set snap traps along walls | Droppings in several rooms, noises in walls, any rats |
| Wasps | A tiny nest you can reach safely | Ground or wall nests, hornets, allergies in the house |
| Roaches | — | Any German roaches; they spread fast |
| Termites or bed bugs | — | Always — DIY treatments rarely reach them |
| Wildlife in the attic | — | Always — licensing rules and the risk of trapping babies inside |
For year-round protection, our recurring home pest control comes with a 100% satisfaction guarantee. Same-day appointments are often available.

Bergen County Pest Questions
What is the most common pest in Bergen County?
Mice are the most common household pest we see in Bergen County, especially from October through March. Ants are the most common in spring and summer, and yellowjackets and wasps lead the calls in late summer.
When is pest season in Bergen County, NJ?
There isn't one pest season — it changes through the year. Spring brings termite and ant swarms, summer brings stinging insects and mosquitoes, and fall and winter bring mice, rats and wildlife looking for warm shelter.
Are termites common in Bergen County?
Yes. Eastern subterranean termites are common throughout North Jersey, including Bergen County. They live in the soil and can damage a home for years before anyone notices, so an inspection is worth it if you see swarmers or mud tubes.
Why do I get mice every fall?
Mice move indoors when nights turn cold and outdoor food gets scarce. They come in through small gaps around pipes, vents and garage doors, so sealing those openings before October is the best prevention.
Do Bergen County homes get ticks?
Yes, especially homes with wooded edges, tall grass, leaf litter or deer passing through. Blacklegged ticks, which can carry Lyme disease, are found in New Jersey, so check yourself, kids and pets after time outdoors.
How often should I get pest control in Bergen County?
Many homes do well with seasonal recurring service, which handles the spring insect season and the fall rodent push. Others only need a one-time treatment when a problem appears. We'll recommend what fits your house.
Is it safe to remove a wasp nest myself?
A small paper wasp nest you can reach easily can sometimes be handled carefully, but ground and wall nests, yellowjackets and hornets are risky. If anyone in the home is allergic, don't try it — call a professional.
Do you serve all of Bergen County?
Yes. We're based in Garfield and serve towns throughout Bergen County, as well as Passaic, Essex and Hudson counties. Same-day appointments are often available.
Are bed bugs a problem in Bergen County?
Bed bugs can show up anywhere people travel and move furniture, and apartment buildings see them most often. We offer bed bug heat treatment and can explain how to prepare.
