If wasps repeatedly disappear into the same point in a roof, there is a nest inside. You do not need to see it, and you should not go looking.
If wasps are repeatedly entering and leaving the same specific point, yes. Wasps flying about generally are foraging and mean nothing. A steady two-way stream at one opening means a nest inside.
You do not need to see the nest to have it treated. The entry point is enough — and going into the loft to look is how people get stung badly.

| What you see | What it means |
|---|---|
| Wasps flying about generally | Foraging. Could be from anywhere, including next door |
| A few wasps near the roofline | Possible. Keep watching |
| Wasps repeatedly entering and leaving one point | Nest inside |
| A steady two-way stream at one opening | Established nest |
| Wasps disappearing under a soffit or tile | Nest in the structure |
