      Yellow Jackets vs. Wasps in NJ: What’s the Difference?
Quick ID, why nests pop up under siding, risk factors, and how our treatment + 30-day guarantee works.
Every late summer in Northern New Jersey—Newton, Andover, Vernon, Randolph, Kinnelon, West Milford—we see a surge in calls about “bees” under siding. Nine times out of ten, it’s actually yellow jackets or paper wasps. Knowing which one you’re dealing with helps you pick the safest next step and set expectations for removal.
Fast ID: Yellow Jackets vs. Paper Wasps
- Yellow jackets are stockier with bold yellow/black bands. They often nest in wall voids, soffits, or underground cavities. Flight is rapid, “busy,” and direct.
- Paper wasps are slimmer with long dangling legs in flight. Their nests are open and umbrella-shaped, typically under eaves, deck rails, and porch ceilings.
- Hornets (overview) are larger and build enclosed paper nests in trees or high eaves; the behavior and hazard profile differ, so the removal approach does too.
Why Nests Show Up Under Siding
Gaps around utility penetrations, soffit returns, and trim provide protected entry points. As colonies grow through July–September, they seek larger, warmer voids. Vinyl and aluminum siding can hide significant nest activity, so you may only see traffic at a tiny gap—but inside could be a large colony.
Stings, Safety & When to Call a Pro
- Nest is in a wall, soffit, or tight structural area (risk of indoors migration if disturbed).
- Entry near doors, walkways, play areas, grills, or dog runs.
- History of allergies or increased sensitivity to stings.
- Repeated rebuilds: prior store-bought sprays rarely solve hidden void colonies.
What Our Stinging Insect Service Includes
We perform a targeted treatment at the entry and nest zone, using precise applications that follow product labels. When accessible, we remove the nest. For yellow jackets we include a 30-day guarantee at the treated site. Our techs communicate clear re-entry times and simple post-treatment steps.
Prevention for NJ Homes
- Trim vegetation back from rooflines and fascia to reduce harborage and scouting.
- After the colony is eliminated, seal utility gaps and trim voids with appropriate materials.
- Use lidded trash cans; clean spills after outdoor meals, especially late summer.
- Schedule early-season inspections if your home had nests in previous years.
