honestly you dont have to waste your money going to the vet. its at least 75$ for the vet to tell you everything that we just did. it sounds like you dont have to worry much because its still eating so its not a huge case of mite just a lil one. you shouldnt have a problem gettin rid of um wit the instructions we gave. good luck
Also with the shed dont worry bout keepin the humidity up cuz you will be soaking him weekly anyway.
