That's a great question! Finding an outdoor trash can that looks good and actually keeps critters out is a common challenge. From my own experience and research, the key is to look for specific features rather than just a "sturdy" bin.
First, the locking mechanism is everything. Look for cans with robust, locking lids that require a human hand to open—simple flip lids won't deter a determined raccoon. Brands like Simple Human and Rubbermaid offer models with locking clasps that are very effective. Metal bins, especially stainless steel, are generally more chew-proof and durable than plastic against persistent animals like squirrels.
For attractiveness, consider integrated models that hide within deck enclosures or stylish stainless steel bins that look more like modern patio furniture. Earth-toned or black plastic bins also tend to blend into garden settings better than bright colors.
My top recommendation is to search for certified "bear-proof" or "wildlife-resistant" cans. These are rigorously tested and often feature locking lids and sturdy construction. While an investment, they truly solve the problem. Placing your can in a shaded, secure spot away from fences can also help.
Ultimately, the perfect balance is a bin with a secure, locking lid made of durable metal or thick plastic, in a finish that complements your outdoor space. It’s worth spending a bit more for peace of mind and a tidy yard.
