I bought my BP from a pet store about 2-3 weeks ago....I noticed one or 2 black little balls on him a few days after having him and searched what it could be...mites! Well, they told me they fed him the day before i bought him and not to feed him for 1-2 weeks it was up to me. I noticed more mites and bought a spray but didnt take out the substrate...today i took out everything but 1 hide and paper toweled the floor, i put him in light soapy water and cleaned the entire cage. The little guy however is really really weak. I mean like i put him in the water and his head went under...he is limp, so i quickly picked his head up and placed it on the ledge and let him stay in there for a little while i cleaned the whole cage. A bunch of mites died in the water and from what I could tell there is none on the snake anymore and nothing in the cage, I know there are probably eggs. I do still have the spray which i will use every 3 days like it says....i'm thinking about also using the Provent A Mite that many people here say to use. I'm thinking about 90% of them are gone, but he is really weak and looks skinny....i tried to feed him this morning and he didnt go for it. What should I do from here to keep him alive? I really don't want to lose this little guy and I guess this is a lesson learned to not buy anything from a petstore who doesnt care about its animals.
