The value placed on tarantulas in the pet trade has led to high rates of collection and trafficking from Mexico. For this reason, all species of the genus Brachypelma have been included in Appendix II of CITES. This is the only genus of spiders to be recognized as endangered by CITES. The extreme rarity of several species of Brachypelma, combined with potential threats of habitat degradation and illegal trafficking, has led to the need for captive breeding for future reintroduction. Brachypelma klaasi is the rarest and most threatened of Mexican tarantulas. It is a long living, slow growing species. With a high proportion of pre-adult mortality; less the .1% of individuals are estimated to survive from egg to adult in the field.
