I found it very easy to use a snow owl if you have one. Let's say it's just floating up there in the sky and you can't seem to get it down. Use the freeze ability and it will force it to land, where then you can proceed to chain Bola it from a ground unit. It won't cause aggro to freeze it either so there's that. I did the same thing with a quets and it was relatively the same results, except the quets took back off again after about 3 seconds or so.
