Outdoors, shes doesnt get sawdust in her hutch or near any treesIs your rabbit indoors or outside?
Where you grow??
If you have 2 rabbits together and only one has got the mites, they should both be treated. While they are being treated it is a good idea to remove them from their hutch so that any mites have time to die off. This can take up to 6 weeks during which time you can give it a thorough clean. If you have somewhere they can live temporarily this must be cleaned out every day so that eventually the rabbits and their environment have become mite-free.
