Havahart® Large collapsible traps have a space saving design ideal for easy storage. When ready to use, just lift handle and trap pops into place! Havahart® large collapsible traps are constructed of sturdy rust-resistant wire mesh with steel reinforcements for long life and galvanized for maximum resistance to rust and corrosion. Mesh openings on these animal traps are smaller than competing traps of comparable size to prevent escapes and stolen bait.
