How to deter wasps~~ if you make a fake wasp nest it will keep them away because wasps are territorial and they will think the territory is occupied. All I know is that it should be round and gray. So I balled up a grocery bag and covered it with weather resistant duck tape; also, I broke the hook of a coat hanger so I could hang it. It worked like a charm all summer: no wasps, no pesticides!
