For example, the bulldog bat found primarily in the tropics, is a fish-eating specialist. Only Vampire bats feed on blood from other animals. Their prey is not humans like in the movie Dracula, but mostly livestock or chickens. A small incision is made with their sharp teeth and the exuding blood is consumed. These bats are mostly found in Central and South America.
Gophers are a very common rodent found in most areas of North America.
They live exclusively underground where they can destroy plants by consuming the roots or pulling the whole plant down into their burrows. The most effective method of removing gophers is through trapping. Specialized traps are available at most hardware stores. Also available are poisoned baits, which are placed within the gopher burrow, though it is often difficult to find a bait attractive to your particular gopher. The least effective method is the garden hose.
