Everyone talking about bringing pests in the closet - I hear you. But if I don't plan on using it again for a year or so, can't I do this now, and spray real well afterwards? How long can these pests live in a Rubbermaid shed w/o any plants in it? Thx to all - I wouldn't consider doing this if I felt OK leaving them in my backyard, but these are getting bigger all the time, and prying eyes next door could pop me.
