Dealing with seagulls constantly getting into your trash can be incredibly frustrating. I've been there myself, watching those clever birds pry open lids and create a huge mess. The most secure outdoor trash bins for deterring seagulls are typically those with a locking or latching lid mechanism.
Look for bins labeled as "animal-proof" or "raccoon-proof," as these are also designed to thwart seagulls. Key features to prioritize include a sturdy, lockable lid that requires a human hand to open, often with a pedal or key. Smooth, rounded tops are also excellent because they offer no foothold for the birds. Heavy-duty materials like thick plastic or metal prevent them from pecking through. Weighted bases or the option to secure the bin to a post can add another layer of security. While no bin is 100% seagull-proof, a model with a robust locking system is your best defense for keeping your outdoor area clean.
