There’s nothing more frustrating than hiding or skittish fish. Part of the joy of having a water garden is to sit by the pond’s edge, feed your fish and relax while you watch them enjoy their underwater world. When they dash off and hide at the site of anything coming near them it almost defeats the purpose of having koi or goldfish in your pond! The most common water garden predators are herons and they can clean up in one afternoon. It is important to know your enemy and using the tips below will help to discourage predators from your pond.
Use a Decoy
Your first plan of defense should be setting up a realistic Blue Heron Decoy. Heron are territorial by nature, and when one cruises overhead and sees that one of its feathered cousins (fake or real) has already claimed the area, it’ll keep going until it finds its own pond to fish. Move the decoy regularly to make it appear even more realistic. Another expert tip: Remove heron decoys during mating season, which runs from March through late May or June.
Make the Pond Perimeter Difficult to Access
Heron refuse to land in water and hate stepping over wires, so we recommend Heron Stop as a second line of defense around the perimeter of your pond. The impassable barrier – made up of nylon line and stakes – prevents the bird from approaching and protects up to 40 feet of shoreline without blocking your view.
Provide Pond Coverage
Barriers like pond nets, prevent the birds from landing in your water feature and spearing your fish. Planting aquatic plants that cover the surface of your pond will also make your fish difficult to spot. The harder they are to find the harder they are to catch.
Set Up a Motion Detector
For a final layer of protection, set up a ScareCrow® Motion Activated Animal Deterrent. Thanks to a built-in infrared sensor that detects movement up to 35 feet in front of it and up to 45 feet wide, this heron-scaring tool chases off unwanted visitors with a surprise spray of water. It works both day and night to set boundaries around your water garden or koi pond.
