Toxic to Humans
Allergenic
Toxic to Humans
Yellow-spotted millipede possesses a defense mechanism that releases hydrogen cyanide, a cyanogenetic compound, when threatened. Direct touch or ingestion by humans can lead to mild toxic effects due to hydrogen cyanide's ability to inhibit cellular respiration. Symptoms might include dizziness, headache, or nausea. No skin penetration occurs, and there are typically no severe effects from casual contact. However, high concentrations or prolonged exposure can result in more significant health complications.
Does the Yellow-spotted millipede cause allergies?
Yellow-spotted millipede, at both adult and juvenile stages, deploys defensive chemicals that can cause mild allergies in a small subset of humans. These allergies typically manifest through skin contact, leading to symptoms such as irritation or itching. Most people are at low risk, though susceptible individuals should handle with caution to avoid allergic reactions.
