If you are a gardener or farmer, or have a pond or stream on your property, ducks can be valuable allies in natural pest control. Watching these feathered vacuum cleaners enthusiastically hunting for and devouring pests both on land and in water is extremely satisfying to anyone who has struggled to find practical and safe methods to control the harm done by garden and farm pests. Here is a picture from the duck family at the Central Rocky Mountain Permaculture Institute in Basalt, Colorado.
The primary step in pest control is to recognize the trouble. Specifically when plants are involved, the trouble could involve inadequate growing conditions instead of an attack from an invasive pest. In some cases recognizing the pest is evident, if you see a computer mouse scampering across the floor it is obvious you require for pest control.
