These guards are typically conical or disc-shaped and are designed to stop rats from climbing by creating a physical barrier they cannot pass.
In summary, rat guards serve as a crucial tool in protecting vessels, storage facilities, and offshore installations from rats, preventing potential damage and health risks caused by these pests.
The guards are generally made from metal or durable plastic and feature a smooth, sloped surface that rats cannot grip or climb.
When installed correctly, the shape of the guard causes rats attempting to climb to slip off, preventing them from reaching the other side.
These devices are particularly effective because they exploit the rats' inability to navigate the smooth, conical surface of the guard.
