Steady two-way traffic at one point in the roofline is a nest. Not wasps passing through, not a few strays — a colony, inside the structure.
A nest inside the roof or the roofline. Steady two-way traffic at a single point — some going in, some coming out, continuously through the day — is a colony, not passing wasps.
It will grow through the summer. A nest noticed in June is much smaller than the same nest in August.
| What you see | What it means |
|---|---|
| Steady traffic in and out of one point, all day | A nest inside |
| Traffic increasing week by week | A growing colony |
| Wasps circling the eaves without entering | Possibly scouting; watch for a few days |
| A few wasps at a window indoors | They may have come in from a roof nest |
| Wasps on fallen fruit or a bin | Foraging, not nesting |
| A visible papery nest under an eave | A nest, in the open |
| Wasps at a flower bed | Foraging |
