It's easy enough to catch a fly in a cup. I did it several times to feed my brother's chameleon when I was a kid (the lizard would not eat dead flies, but would eat any live one you put in there).
So you catch it in a cup, and pump in some nitrous oxide. When the fly passes out, you can have your way with it.
