my rodents are in the same room that was dusted 2 days ago i could do it daily and it would still look like that. The one down side to pelletized bedding is it is very dusty. All of our snake,rodents, and adult crested. Plus 2 bearded dragons are in a 10x12 room. not to mention my house is almost 60 years old dust builds up daily. But thanks for the input.
