What do rose hair tarantulas eat?

All spiders are carnivores. Rather than spinning a web and sitting in ambush, tarantulas actively forage for prey. In many ways, they are like arachnid big cats. Their preferred hunting tactic is to creep up as close to a potential prey item as possible before pouncing and physically overpowering it to deliver a lethal bite. Tarantulas prey on a wide variety of insects and other arthropods but thanks to their size and strength, they can even take down small lizards and rodents on occasion.

Are rose hair tarantulas dangerous?

Despite their particularly fearsome appearance tarantulas rank among the least dangerous of all spider. They do possess huge, dagger like fangs that can administer a very painful bite, but their venom is only about as potent as that of a honey bee. Barring an allergic reaction, people generally have to worry more about the mechanical damage from the bite than from the toxin. Tarantula venom’s main purpose is to liquidate the innards of prey for consumption. Their primary defense is the urticating hairs on their abdomens. These barbed hairs are easily dislodged and causing burning and irritation. However, rose hair tarantulas are known for their docile dispositions and rarely throw hair let alone bite. In fact, this species ranks among the most popular pet spiders in the world due to their ease of care and handleability.
