They do have urticating hairs, but instead of throwing them, they just knock them off onto your hand if held. Some hobbyists may react badly to these, but in general, most hobbyists don't react too much to Avicularia spp. The genus Avicularia doesn't contain any species that have a medically significan't venom, but individual keepers may have some reaction to a bite. They don't understand nor have a need to be handled. They are venomous like many spiders, but their venom is not dangerous unless your allergic to their venom.
Adults breed easily and eggsacs are commonly produced in captivity.
Captive born spiderlings are always available on the market. Join the Arachnid Mailing Lists on the internet.
