If you want to "stun" the BG, just put them in a bucket with a small amount of clove oil added to the water, and they'll be lethargic when thrown back into the pond.
Do you then put some clove oil on your crankbait when trying to catch your big bass?
My pond fluctuates from a puddle to a swamp, and I've got dozens of plano boxes loaded with crankbaits. I rarely get to use them, and I sure miss fishing with them. 10" ringed curly tailed worms with a tiny 3/16oz tungsten bullet weights are my go to bait for larger LMB. Watermelon is their color of choice.
