I'm with you on that being in the house.
Don't think I would like critters in mine either and especially not under my bed. chills..... IF those things got out, I KNOW they would get in the bed with me and chills um...Sure as I am sitting here, the dog would knock the top off or someone would put something under the bed and knock the top off OR something.
Might have to just do them in the summertime in the garage.Bet they wouldn't survive over winter in the garage unless it was heated. I shouldn't need but a few to get them started eating the poop under the roost though. I wouldn't think so anyway.
