The swarm 50ft up a tree may be moved down to a much lower branch,
from which they can then be conveniently dropped off into whatever box you
plan, by shining a very bright light as a spot on the top of the swarm.
Given a clear sun and lucky geometry, you can use a hand mirror, which I
have found to work a treat (tho' does take perhaps 10min).
I haven't tried this with an artificial light. Whether it's the
light or heat or both I have no idea. It is only about 50W of visible plus
IR so I doubt it can do serious harm.
Several friends have also done this. The method seems to be
fairly widely known in New Zealand; I don't know about elsewhere. It is
for some reason quite fun - the fluid glob moves steadily downward by
remote control. Gives you that Overlord feeling, perhaps.
But then, I like swarms in many ways.
