No idea if this would be an issue or not, but I wouldn't chance the strip. I'd be too afraid that there would be some residue left and that it might harm my animals. If you have a deep freeze with some spare space, you could just freeze it in small batches, maybe in a small tote or plastic grocery bag, for 2 or 3 days. That would definitely kill any live mites and should finish any eggs too. I also try to source my bedding from outside the pet industry when possible, its usually cheaper and shouldn't contain any mites.
