That's an excellent and very practical question! It's a common frustration for many homeowners and campers. The good news is, yes, there are definitely outdoor trash bins designed specifically to be difficult for animals to get into. The most effective ones typically share a few key features.
First, look for bins with locking or latching lids. Simple flip lids are no match for clever raccoons or determined dogs. Bins with sturdy clasps, often requiring a button press or a key to open, are much more secure. Some high-end models even have combination locks.
Second, the construction material matters. Thin plastic can be chewed or clawed through. Opt for heavy-duty, thick plastic or galvanized steel bins. They are more durable and resistant to forceful attacks.
Third, consider the design of the lid and body. A smooth, rounded body without lips or ledges makes it hard for animals to get a grip to tip the bin over. Tapered sides can also help. Some specialized "bear-proof" bins have a complex lid mechanism that requires dexterity (like pressing a lever and lifting simultaneously) which most animals lack.
Popular animal-resistant options include bins with locking bars that secure the lid to the body, cans with a screw-top design, and containers that are certified by agencies like the Interagency Grizzly Bear Committee (IGBC). Brands like Tuffy, Bearicuda, and Simplehuman offer robust models.
Ultimately, the "most difficult" bin depends on your local wildlife. For raccoons and dogs, a sturdy locking bin is often sufficient. For areas with bears, you'll need a certified bear-resistant container. Anchoring your bin to a post or wall adds an extra layer of security. Investing in a proper animal-proof bin saves you from messy clean-ups, protects local wildlife from harmful foods, and is a responsible choice for your community.
