That's a great question! Dealing with odors from outdoor trash cans is a common challenge, especially in warmer weather. Luckily, there are several effective options that can make a big difference.
For a simple and natural start, baking soda is a classic. Just sprinkle a generous amount at the bottom of a clean, dry can. It's excellent at absorbing odors. You can also place an open box inside. For a fresh scent, try adding lemon or orange peels on top of your trash bags.
If you're looking for a more dedicated product, I highly recommend deodorizer pods or discs designed for trash cans. Brands like Lysol or Febreze make solid ones that clip under the lid or stick to the side. They slowly release odor-neutralizing scents for weeks. Another fantastic category is activated charcoal or bamboo charcoal bags. These are unscented, purely absorbent, and can be reactivated in the sun every few months, making them a long-lasting, eco-friendly choice.
My top tip is to combine methods: use an absorbent base like baking soda or charcoal *and* a scented pod for the best results. Most importantly, ensure your cans are cleaned periodically with a hose and a disinfectant. A clean can is the first step to an odor-free one.
