A honey bee swarm vs a wasp nest
Two things people find in a garden and frequently confuse, with different consequences. One is a colony reproducing and should be collected; the other is a nest and may need nothing at all.
Which to choose
If it is a hanging cluster of furry insects, call a beekeeper — they will usually come free and are pleased to. If it is a papery nest with smooth yellow-and-black insects, leave it alone unless it is in a doorway or a wall you need to use. Do not spray either.
Why these get compared
A large mass of flying insects produces the same alarmed phone call whatever it is, and the right response differs completely. This comparison is about identification and what to do.
Where they differ
| Axis | Honey bee swarm | Wasp nest | Why it matters |
|---|---|---|---|
| What you are seeing | A cluster of bees hanging on a branch or wall, often football-sized | A papery grey structure, sometimes enclosed, with insects entering and leaving | A swarm is bees clustered on the outside of something. A wasp nest is a built structure. |
| The insects | Furry, brown and gold, rounded | Smooth, bright yellow and black, narrow-waisted | Wasps are hairless and sharply marked. Honey bees are furry and duller. |
| Behaviour | Clustered and quiet; a swarm is usually docile | Continuous traffic in and out; defensive near the nest | A swarm has no stores and no brood to defend and is at its least defensive. |
| How long it stays | Hours to a couple of days | The whole season, until autumn | A swarm is in transit. A wasp nest is a residence. |
| What to do | Call a local beekeeper — most collect swarms free | Usually nothing. Wasps are predators of garden pests and the nest dies in autumn | Beekeepers actively want swarms. Wasp nests only need removing if they are somewhere genuinely awkward. |
| Value | A free colony to a beekeeper | Substantial pest control; also pollinators | Wasps kill enormous numbers of caterpillars and aphids and are among the more useful garden insects. |
Where the difference is overstated
The danger of both. A swarm is the most docile a honey bee colony ever is. A wasp nest more than a few metres from where people pass is almost never a problem, and it will be empty by November.
