Effectively prevent predator
Predators are everywhere and it is so hard to prevent?
It takes ten years to accumulate 1,000 bird's nests. Once the natural enemies arrive, the whole house may be empty.
One of the best ways is to use electric fences, which can effectively control all kinds of predators.
Among them, natural enemies such as birds, pigeons, snakes, mice, owls, lizards, and bats can all be solved by electric current.
