That's a common and frustrating problem! A tipping trash can is messy and attracts pests. Luckily, there are several effective and often inexpensive ways to secure it.
First, consider the placement. Position your bin in a corner, against a wall, fence, or between two sturdy objects like a downspout and your house. This creates a natural barrier that prevents it from rocking too far if someone leans on it.
The simplest solution is to add weight. You can place a few heavy bricks or a flat paver stone in the bottom of the can liner. For a more discreet option, fill a sealed plastic jug with sand or gravel and place it at the bottom of the can. Some people also use commercially available trash can weight systems that clip onto the bottom.
For a more permanent fix, try anchoring it. You can use bungee cords or sturdy rope to loosely tie the handle of the can to a nearby fence post, deck railing, or a ground anchor stake. Don't pull it too tight—you still need to lift the can for collection. For wheeled bins, a simple wheel chock or a block of wood behind the wheels can prevent rolling.
Finally, invest in a sturdier can. A heavier, commercial-grade plastic bin with a wide, flat base is inherently more stable than a lightweight, tapered model. Look for cans specifically advertised as "tip-resistant" or with a low center of gravity.
A combination of these methods usually works best. Start by adding weight and repositioning the can. If it's still a problem, a gentle anchor should do the trick. Good luck
