trust me it works just like youve been reading. Ive used it and havnt seen a mite since i did the first spraying. You can spray the carpet if you want and around the cage or rack what ever you keep your snake in. This is prevent them for up to a month and it also kills any eggs laid by the mites. Depending on how bad the infestation is you may need to reapply it another time. But one time worked for me.
