I used 0000 steel wool, wooden mouse traps with cheap Menards PB. After you catch mouse, throw the trap away and use a new one. They say they can smell our scent and won't return. Also put them on the sides next to bulkheads as they usually follow near the outer edges. I like the black box/green death but only in winter as they will eat it and crunch extremely loudly at night before they run outside/away to die.
