hi i have had my clumbian ranbow boa for about a year and a hafe now and i just cant seem to get rid of the mites. dose anyone know what to do? i went to a vet and got some meds but it worked for a while and now they are back agen. i use repta bark and keep a hight humidity. he is in a 40 breeder with a zoomed basking light and a red heat night light. i have gages on the back wall with temp and humidity. i feed frozen mice.
