Depends on you morals but Golden Marlin fly pellets and Pepsi in a tin pie pan. A person I knew had them chewing up wiring in very expensive earth movers. Made a "dessert pan" for them. No BS he left it for 3 days and had 10 dead 'Coons! Draw a ten foot circle around plate. NOTHING will make it out of the circle. Just be sure nothing you like can get to it. They cant resist the stuff.
