Jim Horton posted this picture of a raccoon disaster. It shows the reason why not to buy cheap mail order or hardware store cage traps. The client set this trap for a raccoon that had gotten into his house. As you can see he caught the coon, but only held it for a short time. The coon simply ripped the door right off the frame. These cheap traps are made with “clipped on doors.” There is a light duty clip holding wire to wire clip at the door hinge point, that will work for light duty animals at times, but not raccoons.
We made the Comstock traps “bullet proof,” overkill, with 1/4 inch door frame rods wrapped around 1/4 inch cage frame rods, impossible to break or come apart. The Comstock traps are essentially escape proof.
