Be very very careful. We lost two guinea pigs because their bedding got sprayed by the pesticide and it wasn't a pretty thing either ... it almost seemed like a neurological problem where they slowly lost function from the back to front. Needless to say my snakes are in my room and that room does not get sprayed and any bedding goes straight from its source to my room. I actually just saw a very large brown recluse spider in my room but I'm willing to run the risk of getting bit by one because I will not have my room sprayed.
