Wasp vs Hornet
Polistes fuscatus vs Dolichovespula maculata
Every hornet is a wasp, so the useful question is which wasp you have. The nest answers it faster than the insect does: an open umbrella of visible cells is a paper wasp, and a big grey paper football is a bald-faced hornet — which is far more defensive and worth more distance.
The one thing that settles it
Open comb versus enclosed envelope. A paper wasp builds a small open comb on a stalk, and you can see the individual cells from below. A bald-faced hornet encloses its comb in a grey paper envelope with a single entrance near the bottom. You can read this from a safe distance, which is more than can be said for the insects themselves.
Side by side
| Character | Paper Wasp | Bald-faced Hornet |
|---|---|---|
| Danger | Take care | Take care |
| Nest | Open umbrella comb on a stalk, cells visible | Enclosed grey paper envelope, football-sized |
| Colony size | Small — often a few dozen | Large — several hundred workers |
| Face | Brown to reddish, no white | Ivory-white — the only common wasp with a white face |
| In flight | Long legs trailing beneath, slow and deliberate | Legs tucked up, faster and more direct |
| Defence range | About a metre from the nest, and it ignores you beyond that | Several metres, and it will spray venom at eyes at the nest |
| Interest in your food | None | None — that is the yellowjacket |
Why they get confused
The word hornet is used loosely for any large stinging wasp, and in North America the animal people call a hornet most often is not a true hornet at all — the bald-faced hornet is a large yellowjacket relative. Meanwhile the actual true hornet in the US, the European hornet, is comparatively rare. So the everyday distinction is really between a small open-nesting paper wasp and a big enclosed-nesting one, and that is the distinction that predicts how much room you should give it.
If you still can’t tell
Judge by the nest and keep your distance from whichever it is. If guards come out to face you, you are already close enough — that is true of both, and it happens several metres out with a bald-faced hornet. A nest high in a tree and away from paths can usually be left alone entirely; both species abandon the nest in winter and never reuse it, so a nest found in autumn will resolve itself.
Common questions
Is a bald-faced hornet a real hornet?
No. It is a large relative of the yellowjacket. No true hornet in North America has a white face, so the face alone rules it out.
Which sting is worse?
Comparable individually. The difference is quantity — a bald-faced hornet colony responds together and each wasp can sting repeatedly, so the realistic bad outcome is multiple stings rather than one worse one.
Can I remove a nest myself?
A small early-season paper wasp nest, often. A mature bald-faced hornet nest is a professional job — it is the species most likely to produce a multiple-sting incident.
Do they come back to the same nest next year?
Never. Both colonies die out over winter and new queens build elsewhere. An old nest is empty and can be removed at leisure.
