LH, tarantulas are harmless. They never bite. And no matter what spider you hold in your hand--even a black widow or brown recluse or Aussie funnel web--they can't bite you because you present a flat surface to them and they cannot bite into a flat surface. When people get bitten by spiders, it's generally because they sat on it, donned a shirt or a shoe with a spider in it or picked clothing up off the floor where a spider was resting. In these cases, it gets squeezed and it will either bite in self-defense or its fangs are actually driven into the skin by the cramped situation.

But handling a tarantula is easy and they are feather light. People expect them to be heavy but they weigh almost nothing. You can handle wolf spiders and trapdoor spiders as well. They simply don't bite unless squeezed. Spiders are a natural pesticide and we can never have too many of them in this world or we'll be fighting a losing with rapidly expanding insect populations that would make it impossible to live. And if faced with the occasional spider prowling up the wall or across the ceiling or a roach infestation--which would you rather have?
