Do you think the dish soap is bad or good for the plants?

What is it about soapy water that knocks house flies right out of the air?

In case you want to know why, I use the flies to feed the plants.

I'd rather not use soap (for the plants), but plain water doesn't work.

The can't fly with soapy wings.

Bad. You have Venus Fly Trap plants. Still immature. Older ones will
have an orange center in the trap. The plants produce a scent
attraction; creatures like flies, even ants.

I'd feed them via the potting soil / moss, early on. Set them in a
warm window sill and let them catch flies when the are ready. One the
trap closes it will days before it opens (feeding of the protien)

Have you tried a fly-swatter just to kill and collect proteins?"
