I have wasps in the way. There's isn't a lot of direct light in my new yard, so I'd been working on clearing out dead trees to let more in (likely died due to crowding and lack of light). But the stuff that has to go is home to a number of littler wasps who are making their nests in old ornaments and decor left from the previous tenants in the dead branches. I don't want the wasps dead (I like the little guys), and I can't use poison sprays since I myself have a reaction to those. How do I get them to move out? Do water blasts really work?
