Habitat: Protected areas in drier climates.

Feeding Habits: Nocturnal. Hide during the day, hunt by touch in the dark. Eat insects, lizards, and other small animals.

Economic Importance: Control of troublesome insects. Not dangerous.

Natural Control: General biodiversity. Tarantula hawk, which is a large wasp (also called pepsis wasp).

Organic Control: None needed. Tarantulas are beneficial and nonaggressive.

Insight: The tarantula's bite is no worse than a wasp or bee sting--but they seldom bite. They make good pets. Tarantulas eat very little and don't bring fleas into the house. There are no vet bills, they don't bark or wet the floor or tear up furniture.
