Hey there! Dealing with raccoons and other critters getting into your outdoor trash is frustrating, isn't it? I've been through it myself and found some really effective solutions.
First, consider investing in animal-proof trash cans. These are specifically designed with locking lids that raccoons' clever paws can't easily open. Look for cans with sturdy latches or even ones that require a button press to open.
If you're not ready to replace your current bins, simple bungee cords can work wonders. Just stretch a heavy-duty cord across the lid and hook it to the handles on both sides. This creates tension that most animals can't overcome. For extra security, use two cords in a cross pattern.
Another great deterrent is ammonia. Soak a few rags in ammonia and place them in a sealed plastic bag with holes poked in it. Place this bag on top of your trash before closing the lid. The smell repels most animals, though you'll want to refresh it weekly.
Motion-activated lights or sprinklers near your trash storage area can also startle nocturnal visitors away. Animals prefer working in darkness, so sudden light or water will make them think twice about approaching.
Remember to avoid putting particularly smelly food waste directly in outdoor bins. If you have fish scraps, meat bones, or other strong-smelling items, consider freezing them until trash day.
What methods have you tried? I found that combining a couple of these approaches works best - like using a bungee cord on an animal-resistant can. It might take some experimentation to find what works for the wildlife in your area, but these solutions should give you a great starting point!
