Quick answer
Tarantulas feed as carnivores, adjusting with season, age, and what is abundant in Deserts, rainforests, and grasslands. That label is a preferred pattern, not every item an individual might sample.

Tarantula diet overview
Tarantulas (Theraphosidae) are best summarised as Carnivore. Anatomy and habitat (Deserts, rainforests, and grasslands) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How tarantulas find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Tarantula role in the food web
As predators or scavengers, tarantulas move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild tarantulas. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Big, hairy, and mostly harmless
Tarantulas are among the largest spiders, but their reputation is far scarier than the reality. Almost all species have venom no more harmful to a healthy person than a bee sting, and they bite only in self-defense. They are ambush predators that pounce on insects, and larger species may take small lizards or rodents.
Urticating hairs
Many New World tarantulas have a clever defense: they flick irritating barbed hairs from their abdomen at attackers using their back legs. These 'urticating' hairs cause itching and irritation to the eyes and skin of would-be predators, buying the spider time to escape.
