That's an excellent question! Dealing with clever raccoons and other critters getting into the trash is a common frustration. The "best" lock often depends on your specific bin and the determination of your local wildlife, but several effective options exist.
For a quick and highly effective solution, a simple bungee cord with hooks is a top contender. Stretch it over the lid and hook it onto the bin's handles or rim. The tension makes it very difficult for animals to lift, yet it's easy for humans to remove. It's affordable, versatile, and works on most bins.
For a more permanent and sturdy option, consider dedicated lid locks or latches. These are often metal or heavy-duty plastic devices that you can screw or bolt onto your bin, creating a clasp that securely fastens the lid to the body. They provide a higher level of security and are great for areas with persistent pests like raccoons or bears.
Another clever and low-cost method is using a carabiner or a sturdy padlock through the existing handles. If your bin's handles align when the lid is closed, threading a carabiner or a small lock through them can effectively "lock" the lid down. This prevents animals from prying it open.
Many modern animal-proof trash cans come with built-in locking mechanisms. These are often foot-pedal operated or have a button-release that keeps the lid securely locked until you intentionally open it. If you're in the market for a new bin, investing in one of these is your most hassle-free solution.
Ultimately, the goal is to choose a lock that creates a physical barrier that is tricky for paws to bypass but remains convenient for you. A bungee cord or a carabiner is a fantastic place to start. For severe problems, upgrading to a dedicated lock or a bin with a built-in lock is the most reliable path to a pest-free trash area.
