I read you other thread about your BP's Vet visit and you issue with the mites. I'm sorry for your BP has mites, but I have to say the advise your Vet gave you is not the best.
What you really need to do is go online and purchase some Provent A Mite (PAM) and use as directed.
Soaking your snake in Dawn every day for the next 50 days is complete crap advise. It's going to stress your snake, cause the most screwed up sheds you can imagine, and might not get rid of the mites....it's certainly won't kill the eggs that are being dropped in the enclosure.
I don't want to trash on your Vet too much because I'm sure he or she means well, but they just have no idea what they're talking about when it comes to getting rid of mites.
If you do a simple search on the word 'mites', you will know more about the subject than your Vet in about 30 minutes.
