How to Get Rid of Heron Around a Pond

By Jane Ellis ; Updated September 21, 2017
A heron can decimate the fish population in a shallow pond.

Owners of ponds, especially shallow, ornamental garden ponds filled with expensive fish, usually dread the sight of a heron. These beautiful birds can quickly decimate a pond's fish population. For owners of ponds stocked with expensive Koi fish, this can be a real hit to the wallet, as some of these fish are worth hundreds, sometimes even thousands of dollars. Encouraging a heron to move on, therefore, can become a top priority for a pond owner.

Step 1

Patrol your pond on a regular basis. Herons are shy birds that prefer to hunt unnoticed. If you make it a regular practice to scare herons away from your pond, they may eventually look for a quieter body of water to frequent.

Step 2

Add rock features, such as underwater ledges, or vegetation, such as water lilies, that your fish can hide under. Add spots in your pond that are at least 3 feet deep, as herons cannot fish in water that deep. If a heron cannot find food, it will look for other bodies of water in which to fish.

Step 3

Place a net over your pond. If you have a relatively small ornamental pond, you may be able to cover it entirely with a protective netting.

Step 4

Set a motion-activated sprinkler or two that will blast the bird with water as it approaches your pond. Motion-activated devices that make sounds can also be used to scare away herons.

Step 5

Place a heron decoy or fake heron in or near your pond. Herons tend to be territorial and will usually not fish where another heron is present.

Step 6

Add a floating fake alligator to your pond, which may also scare away a heron.

Step 7

Plant high brush or bushes around your pond. Herons prefer to hunt where they have a clear view of any predators that may be approaching.
