Had a buddy of mine set two of my Bluegill traps out in a pond baited with hard dog food. The report today was a bunch of bluegill around the traps but NOTHING inside them. They sat out overnight also. What the heck could be wrong. I used the home-made one years ago and it caught TONS of pinfish in Pensacola Bay. The other trap was store-bought and the design should be perfect for them to swim right in and not easily get out. What could be wrong? What bait do you use when trapping gills??
