 Alternative approaches include biological agents that are sprayed onto infested animals that desiccate the mites, rendering them unable to lay their eggs or consume blood beneath the scales of their host.The incubation period for mite eggs is thought to be about 10–14 days, so the treatment should be repeated after 10 days to ensure that any eggs that hatch or larvae that develop into nymphs are eliminated from the host before reaching sexual maturity and becoming able to repeat their reproduction cycle.To date, no treatment for IBD is known.
