Dragonflies and BT (mosquito dunks)
I'm using some mosquito dunks in the bog area of my pond, since it's slightly separated from the main pond with a retaining wall and is separated from the fish and doesn't get movement from the waterfall.
Today, much to my surprise, I had a blue dasher in my yard. I love the thought of dragons breeding in the pond (assuming they don't get immediately consumed by piggy goldfish). Will the mosquito dunks harm dragon fly larva?
