I have wasps or yellow jackets flying around up near the roof in my greenhouse/glasshouse.
Anyone have any good ideas for wasp repellants? I don't want to spray that foam stuff at them as it just falls to the floor. Is there such a thing as those fly things that were around years ago to clear a room of flies that work against wasps and yellow jackets?
All I can seem to find are products that attract them and trap them. I don't really want to attract them!
TIA for any help.
