Instead, get several and use them in different locations for a period of at least 15 consecutive days. If you're not catching critters after this time period, you can be fairly sure they're gone. Snap traps are the most commonly used household traps. All are designed to kill the rodent quickly and humanely. Snap traps are, well, a snap to use, and can be reused indefinitely if you choose.
Glue boards are a safer alternative to snap traps when kids and pets are present.
They're available in sizes suitable for mice and rats, although rats have been known to escape from these sticky beds. Some glue traps come prebaited, but it's easy to bait them yourself with a sprinkling of birdseed. Glue boards are not reusable, and they don't kill as humanely as snap traps do. Don't set these traps in wet or dusty areas, and make sure to secure each trap with a tack, some wire or double-stick tape. Live-catch traps nab rodents without killing them, but you still have to deal with the pests in some way.
