Toxic to Humans

Nuttall's Blister Beetle contains cantharidin, a substance causing blistering on human skin. The toxin is most potent when beetles are crushed or ingested, leading to burning sensations, swelling, and potential skin penetration at the contact site. Severe cases may experience systemic effects, including gastrointestinal and renal disturbances. Avoid handling; wash hands thoroughly if contact occurs.

Rectangle
Toxic to Animals

Nuttall's Blister Beetle typically delivers a mild venom through its sting, mainly affecting adult stages. This organism can cause discomfort in humans, leading to symptoms such as pain, swelling, and in rare cases, allergic reactions. Domestic animals like dogs and cats might also be impacted with similar symptoms if stung. Smaller mammals, including mice, could experience these effects more profoundly due to their size. Various arthropods are at risk too, which might succumb to the venom depending on their resilience and exposure.
