For the last few years we've had a serious problem with stink bugs and lady bug. I've learned to use the shop-vac to clean my Char-Griller off-set before each use. And NO, smoked stinkbugs do not taste like chicken. Now that I've added my Pit Boss 820, thought I'd get a head start before the bug show up. That slotted grill plate under the hopper box covering all the electronic ain't going to stop'em. What you use, 1/8" hardware cloth over AL. screen?
