First you have to find out where you got the mites from, they dont travel on branches, especially dead branches, Where did u get the animal from?
--------------------------------
you take everything out put it outside, chuck out the substrate,, put the AHD in a large tub
get reptile mite spray - Callington Top of Descent is a good brand
Spray the enclosure down well- getting in every nook and cranny
let it air out for a few hours, return the animal, Use butchers paper for substrate, so you can see any mites,
repeat a few days later, Keep repeating untill you see no more dead mites on the floor
--Take all food/water bowls out before spraying the enclosure. Reptiles can be left in the enclosure if it has good ventilation. Spray thoroughly for 4-5 seconds and spray longer for larger enclosures. Spray the enclosure surrounding area as well. The reptile can be returned to the enclosure immediately after spraying if taken out. Clean out the enclosure and destroy any substrate after spray and old furnishings. Do NOT rinse the enclosure and the reptile after spray. Repeat the above procedure seven days later.--
