I like to dump the pellets out of a couple 12 gage shells, pack 'em with rice and crimp 'em back up. From 20 feet it cleans a hornet nest right off the house without even dinging up the soffit and fascia. I think it might put a grain of rice in each individual hornet, and it's so much fun. Don't use Uncle Ben's though; it just goes to powder. Those loads work great on rats too.
