Stink bug trap! Stink bugs are an invasive species in the mid-Atlantic region of the US. (probably other areas to). This video shows how to make a $3 trap (use a dollar tree LED instead of the pricey Home Depot one), but don't kill the bugs. They make AWESOME fishing bait for pan fish and trout--as long as they are alive.
