We went through this with Bunny... She destroyed EVERYTHING she could get her mouth on while J was at work. We began crating her and waalaa! Nothing else was destroyed. Zeke, Bunny and Eli were all crate trained, and never had a problem with being in there all day while we were at work. Eventually they'll grow out of the need for the crate, I believe. We began leaving them out during the day and nothing has happened really. Just have to keep the trash empty. We tried to crate train Treo, but that was a disaster. So hopefully your brother will have better luck with Jyspy than we did with Treo. (She ate her way out of a METAL crate and folded one side in on herself and escaped.)
