WOW, awesome job! That should do it, I would hope, lol! ANYTHING that survives that, welllll...! Baking the stuff too, on low heat for a decent amount of time, should kill off anything that isn't visible, such as eggs and whatnot. Just don't burn anything down, lol! That said, where did you get the bedding? Did you change suppliers or something or bring a tree branch in from outside or something? Not trying to imply anything or cast blame, just odd that you'd get something like that if you hadn't changed anything or had something introduced somehow. If you could drown one of the little boogers and take it to an exterminator, you might get a better idea as to what it was, if you wanted to go to that length. Me, I'd HAVE to know, lol! Would bug me (hahahahaha! pun intended) no end if I didn't.

Regardless, I hope that takes care of it for you and isn't an issue any longer.
