Ok really pissed here! I have been keeping ASFs for 2 years now noooooo problem for my very modest 15 count BP collection. And every 3 months or so I go to my favorite store and pick up a bunch of mice or rats to feed everyone so they dont get stuck on ASFs. The store is always, clean doesn't smell and they use rat racks like most of us us with the blk tubs. Well 2 weeks ago she had an explosion of ASFs and gave me 20 or so ASFs for free. I picked them out! I checked them over and decided to start a new tub with 1.3 because these females were expecting. I fed off the others. Now that tub has mites!!! They have not spread to my other 4 colonies but what do I do to get rid of them? The 3 females have all had litters so the babies now have them too. Now what? Do I just humanly put them all done? I cant feed them off....Any help appreciated
