Time to deploy my floating Japanese Beetle traps. They worked really well last year. Thousands of beetles came and were gobbled up by schools of bluegills and LMB's. At times there were carpets of beetles with 50+ fish feeding. I don't know if they effectively put weight on the fish (I think they do) but it is fun to watch the fish feed. build one yourself and see:

Cut the bottom from a plastic water jug from the office or Home Depot. file and tape the sharp edge I used automotive weather stripping.
