Here are some tricks to try:
- Use a heron decoy. A decoy like the Pond Logic® Blue Heron Decoy, in your pond.
- Create obstacles around the pond. Herons land around the perimeter of a pond and walk up to the water.
- Startle them with water. For ponds smaller than 1200 sq.
- Provide hiding places for your fish.
Also, do plastic heron decoys work?
No detterents work, netting "helps" but in fact chicken wire is the only 100% protection. Even if a heron finds it cant catch your fish through the netting, they will still try their best to stab the fish and kill them all unfortunately. Decoy herons may help, but they are not 100% guaranteed.
Furthermore, do herons fish at night?
Unfortunately, herons enjoy fishing at night as well as during the day, so this method may only work some of the time, if at all.
Cover Pond To Protect Your Koi
- Get Your Pet Dog to Help Protect Koi. Your guard dog, when trained to stay by or anywhere near the pond, can effectively scare away predators.
- Use Decoys Wisely.
- Install Motion-Activated Sprinklers or Alarms.
- Give Your Koi Safe Hiding Places.
