I have a mite problem with my pet birds and need to treat them and their cage but I have tarantulas in the house. the birds are upstairs in the living room and most of the T's are downstairs, but one is upstairs. I like having her upstairs but I am moving her to the T room. how long do I have to leave her there before bringing her back up. also are there safer ways to treat birds and equipment without harming T's.
