Before you call

What to know about wasps

The problem
A nest in an eave, roof space or wall cavity is the most common emergency callout in this trade, and the one people least want to handle themselves.
How you know
Steady two-way traffic to a single point on the building, usually a gap under the eaves.
What the work involves
Same-day or next-day work in season. Check the hours on a listing before anything else — a nest is not a problem that waits for Monday.
