Other than relocating is there a way you can Snake friendly mask the females scent? I honestly can't say it would work but you could try burning some incense and seeing if that helps out?
As long as you don't go overboard with a very chemical scent I don't think it will hurt the snakes. In my experience at least with incense and even some cleaning supplies as long as it is not directly in the cage my Balls and the one Boa I have seems to never really freak out in their tubs.
No idea if this will work but its an idea!
