Are they likely to do much damage before autumn? If you leave them alone, they'll give up the nest in winter and won't come back next year. Apparently.
Fun fact - Their goo eats through stuff like plasterboard -like alien - I know this because I walked into my kids room one day to find 10 buzzy fuckers circling the hole they had come through 😱
Wasps are eating my soffits. I assume there's a nest inside. Is there a DIY option or do I just have to get someone in.
