Snap traps are most effective and humane by eliminating the possibility of a poisoned rat dying in an inaccessible area, creating serious odor problems. Several traps should be used for maximum effectiveness.

Because rats prefer to travel close to walls, place traps against and perpendicular to walls where droppings, gnawing, or holes indicate activity. This will ensure that the trigger mechanism will intercept the rodent’s most likely path of travel. Pre-baiting of traps (baiting unset traps for two to three days) will encourage rats to explore them, and doubling the amount of traps ensures greater success. Bait traps with peanut butter, bacon, nut meats, dry pet food, or dried fruit. Tying bait on trap with thread ensures triggering of trap.
