How does a single soap drop of "flak" incapacitate a housefly? 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.
