Quick Answer
Bear-resistant containers are essential for storing food and other scented items in areas with bear activity. However, modifying existing containers can be a viable alternative when purchasing bear-resistant containers is not feasible. By implementing the right modifications, you can create a bear-resistant container that meets or exceeds the standards set by organizations like the Interagency Grizzly Bear Committee.
Choosing the Right Container
When selecting a container to modify, look for one made from durable, non-porous materials such as high-density polyethylene (HDPE) or polycarbonate. A 55-gallon drum or a large plastic storage bin is an ideal starting point. Measure the container’s dimensions to determine the number and size of the hardware cloth patches you’ll need.
Securing the Container
To prevent bears from accessing the contents, you’ll need to cover the entire container with hardware cloth, a metal mesh material that’s 1/2-inch in diameter or smaller. Apply a 1-inch-wide strip of hardware cloth around the lid and attach it with 1/4-inch thick screws or bolts. For the sides and bottom, cut 4-foot by 4-foot pieces of hardware cloth and attach them with 1/4-inch thick wire or cable ties. Use a minimum of 2 inches of overlap between each patch to ensure a secure seal.
Reinforcing the Lid and Hinges
To prevent bears from prying open the lid, reinforce it with 1/4-inch thick steel or aluminum plates. Attach the plates to the lid using 1/4-inch thick screws or bolts. Replace the original hinges with 1-inch thick, heavy-duty hinges that can withstand repeated bear attacks.
