Herons are magnificent birds that are often seen wading in ponds and rivers to catch fish, frogs, and other creatures. Unfortunately, their beauty comes with a price. Herons can be problematic as they can destroy the balance of a pond's ecosystem, deplete its fish population, and can be difficult to deter. Fortunately, there are many methods to protect your pond from herons, such as heron deterrents and nets. Heron deterrents are designed to scare herons away from the pond. Netting is another popular method of heron-proofing a pond. It's relatively simple to set up and can be customised to fit any size or shape of the pond.
