Big Gray Paper Nest in Your Tree?

If there's a gray, enclosed, football-shaped paper nest hanging from a branch, a shrub, or the underside of your eave, you have bald-faced hornets — the most defensive stinging insect in Central PA. Don't knock it down, don't spray it from below, and don't run the string trimmer under it. We treat during the day in full protective gear — and where the nest can be taken down safely, it leaves with us.

First: Give It Ten Feet and Text Us a Photo.

Bald-faced hornets defend a zone of about ten feet around the nest, and they don't need much provocation. Vibration is enough — a mower, a string trimmer, a ladder bumping the branch, a car door. Back off, keep kids and dogs out of that part of the yard, and text a photo to 717-379-3248. Identification is free and usually comes back within the hour. If you can safely note roughly how high it is and what it's hanging from, that's most of what we need to quote it.

How to Tell What You've Actually Got

Three different insects build three very different nests, and people call all of them hornets. The nest itself tells you more than the insect does.

Bald-Faced Hornets — the gray football

What you'll see: A closed, gray, papery nest shaped like a football or an upside-down teardrop, hanging from a branch, a dense shrub, a soffit, or a porch ceiling. One small opening near the bottom. Insects are large and boldly black and white — not yellow.

Why it matters: Nests start in spring the size of a golf ball and are often not noticed until August, by which point they can be basketball-sized with several hundred workers. This is the nest that needs professional removal.

Paper Wasps — the open umbrella

What you'll see: A small, open, gray comb of visible hexagonal cells on a short stalk, with no paper envelope around it. Usually under a railing, a porch ceiling, a grill lid, or inside a mailbox. Slender, long-legged wasps that dangle their legs in flight.

Why it matters: Much less defensive and much smaller colonies — usually a couple dozen. They still sting if you reach into one, but they're a far smaller problem, and a nest that isn't next to a doorway can often just be left alone.

Yellow Jackets — usually hidden

What you'll see: Usually no visible nest at all — just steady traffic in and out of a hole in the lawn, a gap in the siding, or a soffit corner. Bright, hard-edged yellow and black.

Why it matters: Different job, different price. If it's a hole in the ground see ground bees; if it's going into your siding see wasps in your wall.

Honey Bees — live removal first

What you'll see: Amber-brown and fuzzy rather than black-and-white. A swarm hanging in the open looks like a solid clump of bees with no paper nest at all.

Why it matters: We're working beekeepers. Honey bees get live removal and relocation wherever the colony can be reached safely. A bare clump of bees on a branch is a swarm — swarm collection is free.

The one-second version Closed gray football with a hole at the bottom → bald-faced hornets, call us. Open comb with visible cells and no envelope → paper wasps, usually leave them. A clump of bees and no paper at all → honey bee swarm, and that one's free.

Please Don't Try These

Aerial nests generate more emergency-room stories than anything else we deal with, almost always because someone tried to handle it from the ground first.

If anyone is stung and shows swelling beyond the sting site, trouble breathing, or dizziness — call 911 first. Then call us.

How We Remove an Aerial Nest

We do these during the day — you're not waiting until after dark for someone to show up. Working in full protective equipment, we puff a low-volume insecticide dust directly into the entrance at the bottom of the nest, which carries through the paper envelope and reaches the colony inside rather than just wetting the outside of it.

If the nest is out in the open and can be taken down safely, we remove it and take it with us. That's the version most people want — the nest goes off your property rather than hanging there for the rest of the season as a reminder. Nests tucked into a soffit return or a dense shrub can't always be removed intact, and in those cases the colony is treated in place. Nests over a walkway, a doorway, or a play area get priority either way.

Cost: aerial hornet nests — the exposed grey ones — run $200–$325, depending on height and access. Multiple nests on one property get bundled. Estimates are free, and a texted photo usually gets you an exact number without anyone coming out.

Worth knowing if you're comparing our prices: an aerial nest is the straightforward one. “Aerial” just means the nest hangs in the open rather than hiding in a cavity — plenty of them sit four feet off the ground in a shrub, and we do a lot of those. Either way it's visible, we can reach it, and it's usually treated and off your property in a single visit. A nest hidden in a soffit or wall void costs more because we can't see what we're dealing with and it takes 7 to 10 days for full control — 14 to 21 in August, while the remaining brood hatches out; a colony that has broken through into the house costs more again.

Will They Be Back Next Year?

Not this colony. Bald-faced hornet colonies die off completely with the first hard frosts, and only newly mated queens overwinter — each one starting a fresh nest somewhere else in spring. An old nest is empty. You don't need to pay anyone to remove one in December. Winter weather usually breaks it apart on its own.

What does repeat is the location. A sheltered eave or a dense shrub that produced a nest this year is attractive again next spring. If you've had two in the same spot, ask about a spring preventive treatment — considerably cheaper than an August emergency.

Frequently Asked Questions

Are bald-faced hornets actually hornets?
Not technically — they're a type of aerial yellow jacket, despite the name and the size. It makes no practical difference to how they're treated, but it does explain why they behave so much like the yellow jackets in your lawn: same aggression, same repeated stinging, same late-summer population spike.
The nest is way up in a tree and nowhere near the house. Do I have to do anything?
Often no. If it's genuinely high, well away from walkways, doors, play areas, and anywhere you'd run a mower or trimmer, the honest answer is that it will take care of itself by November. We'll tell you that on the phone rather than sell you a treatment you don't need. Where it does need to come down is when it's within reach, over a path, near a door, or somewhere you have to work.
How fast can you get here?
Usually same-day or next-day — we hold slots through the summer specifically for active stinging insect emergencies, and these are treated during normal working hours, so there's no waiting for dark. Call as early in the day as you can so we can fit the route.
I found an old nest in a bush over the winter. Is it dangerous?
No. It's empty. Bald-faced hornet nests are never reused — the colony dies with the frost and next year's queens build somewhere new. You can knock a winter nest down with a rake and nothing will come out of it.
How much does it cost?
Aerial hornet nests — the exposed grey ones — run $200–$325 depending on height and access. Ground nests run $165–$225, soffit or accessible wall nests run $225–$375, and a breakthrough into a living space runs $375–$500. Multiple nests on one property get bundled pricing. Estimates are free — text a photo to 717-379-3248.
What else do you handle?
If it's a hole in the lawn, see ground bees. If they're going into your siding, see wasps in your siding or wall. Otherwise: yellow jacket removal, our general stinging insects page, or pest control in Harrisburg. There's also a longer read on why stinging insect nests explode in late summer.
