Knowing Your Local Predators

Pond predators

First, it’s a good idea to know what you’re up against when it comes to predators in your area. You can learn about your local pests and predators by contacting animal control, and/or the county or state fish and game departments.

With their help, you should be able to find out what types of wildlife to watch out for in your area as well as how to best protect your pond. Pond associations are another great resource because they have members who live nearby with potentially more knowledge on this topic than anyone else.

Every predator is different, and some require very specific methods of control. For specific pond predator control, check out these detailed guides:

How to Protect Your Pond From Predators

Fish Caves

Fish caves are an excellent way for you to give your fish some refuge. For these protective structures to work effectively though, they need depth - at least 2' deep with 3' recommended if possible!

Make Your Yard Less Inviting

Pests are looking for food and shelter, so the first way to protect your pond from predators is by making your home less appealing! Keep it free of overgrowth, tall grasses, or other hiding places. Don't leave pet food outside – store in air-tight containers. Avoid attracting snakes with the removal of rodent foods - they're known prey items too!

Pond Depth

The deep end of your pond should have 3 feet or more of water so that predators don't wade into it looking for prey; this not only protects both the predator and its food but also gives fishes a spot to feel safe from outside threats.

Set a Trap

It's easy to forget that sometimes the best way of dealing with a problem is not extermination but prevention. Minks, raccoons, snakes, and muskrats can be deterred by using traps before they have time to cause any real damage.

Plant Cover

Adding floating pond plants, like lily pads, frogbit, and other aquatic vegetation will help hide your fish from pond predators. In addition to providing a temporary hiding spot for the fish, these water-dwelling florae also add nutrients to the water that are key in maintaining a healthy pond environment.

Pet Patrol

A dog is an excellent deterrent to pond fish predators. However, not any old pup will do though. Your best bet is one that has a disposition for chasing after prey; Labradors and Spaniels are good examples of these breeds.

They don't have to learn how to attack a potential predator either: all they need is noise as an effective deterrent. Running towards the pond barking at full volume, and even the rattling of their collar is usually enough to scare off any predator! Be sure to reward your pup for their hard work!

Repellents

Repellents use smell, taste, and/or sound to ward off predators like deer, squirrels, and raccoons. They are very versatile because they can be applied wherever you desire. Just keep in mind, most repellents must be reapplied regularly or after rain.
