The Havahart X-Small 2-Door Trap was designed and tested in the field by trapping professionals. This trap is built to target and trap the smallest critters with ease. Thanks to the trap's careful construction, small animals cannot outsmart this mouse trap. The trip plate is sensitive enough that even the lightest animals like voles and mice can effectively trigger the metal door closed. The mesh openings of the cage are smaller than competing traps, so these little critters cannot steal the bait. Best Used For: Mice, Shrews, and Voles. Constructed with Sturdy, Rust-Resistant Galvanized Steel. Dimensions: 10” x 3” x 3”
