Stink Bug Control in NJ: How to Stop Fall Invasions
Short answer: brown marmorated stink bugs invade NJ homes every fall seeking warmth — no bites, no damage, but hundreds on your windows is maddening. Vacuum them (never squash), seal entry points in late summer, and get a September exterior barrier treatment before the peak.
Why your house becomes a stink bug hotel every fall
The brown marmorated stink bug has been in New Jersey since the late 1990s. Outdoors it's an agricultural pest, feeding on fruit, vegetables, ornamentals, and especially tree of heaven — but every September, as nights cool, adults look for a protected place to overwinter. Your sun-warmed house looks like the perfect shelter.
They arrive in waves. On a warm October afternoon, south and west-facing walls can collect hundreds, drawn by heat radiating off the siding. From there they slip through gaps around window frames, attic vents, soffits, window air conditioners, and utility penetrations. Once inside a wall void or attic, they settle in — and on every warm day through April, a few wander onto your windows. Homes near wooded edges take the heaviest pressure; cliffside homes in West New York North Bergen Secaucus get some of the worst invasions we see.
What to do when they're already inside
Never squash them indoors — the defensive odor lingers on skin, furniture, and walls. Store-bought indoor sprays are nearly useless too, since stink bugs don't feed indoors and die-off in wall voids attracts carpet beetles.
- Vacuum with the stocking trick — stretch a stocking or knee-high over the hose end so bugs collect in the stocking, not your vacuum bag. A stink-bug-filled vacuum smells for weeks.
- Seal the bag outside — tie off the stocking, bag it, and put it in the outdoor trash. Don't flush handfuls: the odor sticks around plumbing.
- Don't bother with indoor foggers — they don't reach wall voids, they don't prevent re-entry, and they coat your home in pesticide for a pest that vacuums handle better.

The real fix happens before the invasion, in late August and September. Stink bugs can't chew through anything — they only walk through existing gaps — so sealing is what wins. Repair torn screens, caulk gaps around window and door frames, screen attic and soffit vents, seal utility penetrations, and pull window air conditioners before October.
The second half is the exterior barrier treatment, timed for September: a targeted application along sun-warmed facades, window frames, soffits, and vents kills them on contact as they arrive and deters the waves that follow. Too early and it wears off before the peak; late October is just damage control. September timing is the whole game.
One more thing: check your yard. Brown marmorated stink bugs feed on tree of heaven, and a stand near the house stages every fall wave. Removing tree-of-heaven sprouts near the foundation cuts local pressure. Our techs in Paramus, Wayne, and Teaneck see this pattern every October.
The bottom line
Stink bugs are the least dangerous pest that drives homeowners the craziest: no bites, no stings, no damage — just hundreds of armored bugs on windows from October to April. Vacuum what gets in, seal before September, and time the exterior barrier right via our North Jersey pest control homepage.

Do stink bugs bite or sting?
No. Brown marmorated stink bugs don't bite, sting, or spread disease. They're a nuisance pest — and a seasonal one. They invade homes in fall looking for a warm place to overwinter, then leave in spring.
Will stink bugs damage my house?
No. Unlike termites or carpenter ants, stink bugs don't eat wood, fabric, or stored food indoors. They don't breed inside either. The damage is to your sanity — hundreds of them crawling on windows, walls, and light fixtures from October through April.
What's the best way to get rid of stink bugs inside?
Vacuum them up — it's the fastest, cleanest method. Put a stocking over the vacuum hose so bugs don't enter the bag (a stink-bug-filled vacuum smells terrible for weeks), then seal the stocking in a bag outside. Never squash them indoors: their defensive odor lingers on skin, furniture, and walls.
When should I seal my house against stink bugs?
Late August through September, before the fall invasion starts. Seal gaps around window frames, attic vents, soffits, and utility penetrations, repair torn screens, and pull window AC units. Once cold nights arrive in October, the bugs are already moving — an exterior barrier treatment in September stops most of them before they ever reach your siding.
When should I call a pro for stink bugs in NJ?
Call when you're vacuuming up dozens a day, when they keep returning despite sealing, or when you want the exterior barrier treatment timed right. Invasion pressure is highest on sun-warmed south and west facades and near wooded edges — homes in those spots benefit most from a professional fall treatment.
