What feature characterizes the best traps for rats?

• A. Expanded triggers (treadles)
• B. Large bait capacities
• C. Padded handles
• D. Electronic triggers

Answer: (A)

Reliable triggering is what makes a rat trap effective. Expanded triggers, or treadles, give the trap a larger activation surface and require the rat to step on the trigger to reach the bait. This creates a more consistent, decisive trigger across different rat sizes and behaviors, boosting capture rates and reducing misses. Bait capacity matters for attracting rats, but it won’t help if the trap doesn’t fire reliably. Padded handles don’t influence the firing mechanism, and electronic triggers add complexity and potential failure in field conditions, making them less robust overall.
