Pest Deterrents - How To Protect Your Fish From Predators
Outer-Pond Protection
- Pond Cover Nets. Covering your pond with a cover net helps to predators away. They are cheap, easy to find, easy to install, and denies predators access to your fish. These cover nets cover the whole surface of the pond and they can also be used to catch debris and prevent chemical imbalances in your pond. The PondXpert Pond Pyramid Shelter Net is the ultimate, innovative net available on the market.
- Pond Protectors. These Pond Protectors come in the form of plastic hexagons that interlock together and float on the surface around the edge of the pond. This stops the herons or other predators getting into the water. Herons tend to stand at the edge and duck their heads in to catch the fish so these pond protectors offer a great barrier to prevent this from happening. They maintain the aesthetic appeal of your pond as they sit just below the surface and are almost invisible from a short distance.
- Fencing. Using an electric fencing may seem like a drastic course of action, but it will deter most non-flying predators from getting near your pond. This shocks herons and cats into looking elsewhere for their supper!
Other Forms of Deterrents
- Decoys. They are creative and can be a decorative way to trick a predator. As Herons are territorial animals, they will not intrude on an area they perceive as dominated by one of their kind. Decoys include a range of products like the classic Decoy Heron and an inedible plastic or metal koi; the predator will not be able to eat through the material and may be inclined to feed elsewhere.
- Spray repellents. Sprays can confuse animals with the use of smell and taste. It is usually cost efficient and can be sprayed anywhere which makes for easy use. Sprays are commonly used to keep cats and dogs away from the pond; they hide any territorial ‘markings’ left by animals, thereby confusing unwanted cats and dogs enough to ensure they do not return.
- Alarms. Alarms, like the SuperFish Pond Alarm, is a motion detector that emits a high-pitched sound which can keep herons, cats, dogs and even children away from the pond. This category can also include having a guard dog; as they will scare away predators with their barking. Alterantively, the Velda Heron Stop Kit can be used to line the perimeter of your pond.
- Wind Chimes. When windy, wind chimes can deter herons by producing a loud noise. If the wind chime is shiny, the reflections can also act as a deterrent.
- Reflective Surfaces. When herons see reflective lights from shiny objects, they become confused and fly away. The Velda Hanging Spinner Heron Deterrent, an excellent reflective surface and has an eye that resembles that of a predator, both of which deter herons from your pond. Alternatively, the Velda Bird Blocker Band can be used as an alternative.
Why do Herons attach garden ponds?
Heron's don't just attack ponds; they go where the food is. Because garden ponds are generally small and full of fish, they are seen as perfect hunting grounds for herons.
Are Herons Protected?
Grey herons are protected under the UK Wildlife and Countryside Act 1981. Killing herons can incur hefty fines and even a prison sentence.
When do herons attack garden ponds?
Herons usually attack ponds early in the morning or late in the evening. It is rare, but not unheard of, that they can attack ponds during the day.
Do Decoy Herons Work?
Heron decoys can work for short periods of time; an approaching heron will notice the decoy and it will think that it is another heron. You will need to move the decoy heron every few days, givinge the impression that the decoy is alive; this will confuse passing herons. If the decoy is smaller than an approaching heron, the approaching heron may land and challenge your decoy for territory!
What is the best Heron Deterrent?
This is a tough question, but we normally recommend a mixture of cover nets, plants (even artificial plants provide shade!), an aerator (they are fantastic at keeping ponds healthy while acting as a deterrent!) and a replica Decoy Heron. This helps to deter herons from visiting your pond, while protecting fish if you do get a visitor!
