Reptile Relief is a natural treatment for mites. It is effective in killing mites in all stages of their lifecycle but has no residual effect. You will need to apply it every 3 days (per the instructions) until you see no more mites. Of course, since there is no residual effect, new eggs may hatch and retreatment may be necessary. As soon as it dries you can feed him if he'll eat. Hope this helps!
