Predators are one of our pond’s worst enemies. They can severely damage the population of the fish. There are many deterrents on the market today, but one
of the best is the Scarecrow. It’s a motion-activated sprayer that works off of a 9-volt battery and connects to a water hose. Whenever a predator comes near, the motion detector is activated and the sprayer is triggered. It is also recommended to have fish caves in your pond which act as a hiding spot for the fish.
