Poisonous arthropods known as venom-mites existed. During the Mandalorian Civil War, Satine Kryze and Obi-Wan Kenobi found themselves under assault by a horde of venom-mites while they were on Draboon; as a consequence, Kenobi was compelled to rescue Kryze by carrying her to a secure location. Kenobi would sometimes compare a particularly awful experience in combat to "bathing in a lake of venom-mites."
The animated series Star Wars: The Clone Wars' second season's thirteenth episode, "Voyage of Temptation," which was initially broadcast on February 5, 2010, marked the initial reference to venom-mites within canon.
