Baiting for Mice, Rats? Try String!

Peanut butter is a staple in managing mice and rats, especially in residential settings. It’s easy to apply to traps, it stays fresh for several days — and a jar of peanut butter has a long shelf life. But peanut butter isn’t always your best bet. Because sometimes that peanut butter is a magnet for other pests — think cockroaches and ants. Besides, a large rodent population might have a wide range of food preferences. And for some, peanut butter might not be at the top of the list.

For those situations, here’s a trick that could help — bait those traps with string! String? Here’s why:

String tied to the paddle of a snap trap is a baiting technique that doesn't feed other pests.

Females can give birth to six to eight litters of pups throughout the year, though they breed more often when it’s warm. They work hard at building nests for their young, and among their favorite nesting materials is string. So just tie a short piece string or dental floss tightly to the paddle of a snap trap and there’s your bait. Be sure to loop your string closely around the base of the paddle. And this is one bait that’ll never spoil.
