a dime sized blop of peanut butter square in the middle.
a couple of thumb tacks to hold it down if a mouse gets in it.
catches roaches for weeks.
the bottom 4" of a plastic 2 liter bottle.
smear the rim with a heavy coating of cooking oil.
pour in 1/2 inch of water and a dab of oil and put your bait on the little mound sticking up.
