Once bulls are in full spawning mode, they are less likely to chase horizontally moving lures and are best left alone to spawn the next generation of trophies. With the spawn completed, big ’gills vacate the flats and push off to deep outside weed edges. In these areas, you can target bulls by casting parallel to the edges with sinking lipless rattling baits, blade baits, and tailspin lures. These can be fished with a yo-yo retrieve to cover multiple depth ranges. Top-producing lures include a ¼-ounce #5 Rapala Rippin’ Rap, ¼-ounce Rat-L-Trap, ³⁄₁₆-ounce Johnson Thin Fisher, ¼-ounce Big Dude Blade Bait, and Biwaa Divinator Mini. The size, flash, and/or noise of these lures will draw large bluegills out of the weeds.
