Why not take a few bottles (or vials) and the flies home with you.
Until they are cleaned up they don't serve for experimental purposes and
so you do not really need to keep them in an incubator. Transfer them
carefully so as not to shake the mold into the new bottle. I have done
this in the past and let the flies transfer themselves by inverting the
new bottle over the old and letting them walk in. Now you can use the
method suggested above.
