I'm looking for ideas on how to prevent wasps from taking up residence behind my vinyl shutters.
I've considered filling the back of the shutters with styrofoam cut to fit all the nooks and crannies, making the shutters essentially solid.
The shutters are going on vinyl siding, so there will still be gaps behind the shutters, but I think the wasps like the total privacy of being inside the shutters themselves.
Thoughts?
