spraying the area around around their encosures might be a good idea if you can do it Gin. Also...and not to get personal but my wife found on the net that washing your body with head and sholders shampoo will help keep them off human bodies. The time years ago when we had a mite outbreak we used and it did help...as gross as it is to say they where getting on us as well since we had to treat the animals and such. I think its a mineral or chemical in it that detered or even helped kill them.
