What are the chances of you putting a couple of the traps over the pond, without any poison, and feed the fish ?
I might give that a try after the dam is closed up and it’s back to full pool and full of fish.
What I’ve been doing is emptying the bug bags into a bucket of soapy water, then digging a hole in the garden, dumping the dead bugs in the hole and burying them.
Fish carcasses are good fertilizer, why not bugs?
