Animals that may experience discomfort or poisoning include humans, domestic pets like dogs, as well as various small amphibians and insects. While larger animals may only feel mild symptoms upon being bitten, smaller creatures can be more severely affected due to the relative potency of the toxin in relation to their body size.

Eastern parson spider is not characteristic of biting humans. Instances of such behavior are rare and usually a result of direct contact or provocation. When they do bite, it is primarily for defense and the consequences are typically mild, without severe implications for human health.
