How Many Mice Traps Should I Set?

What this trap & bait calculator do?

How Many Mice Traps Should I Set? This tool provides a clear visual guide showing the minimum number of traps or bait stations required to begin effective rodent control for both mice and rats. The number displayed is not a strict rule but a practical baseline that ensures you have enough trapping or baiting points to interrupt rodent movement and start reducing the population. In real conditions, traps should be placed along walls, around the perimeter of the house or yard, and at all known entry points, gaps, crawl spaces, and high-traffic routes. Proper spacing and strategic placement greatly increase catch rates, improve bait uptake, and reduce the time needed to eliminate an active infestation. Using the recommended minimum setup helps homeowners, technicians, and DIY users understand how many traps they realistically need—not just one or two—so the treatment is strong enough to work from the very first day.
