Are Red-spotted ant-mimic spider harmful to humans?

Corinnid sac spiders usually do not bite, and may only bite when feeling coerced. The bite of the round-jaw spider is not fatal, the pain is similar to that of a wasp sting, and this pain can last for several days. In addition to the same redness and swelling, many people will have different degrees of infection in the wound. Those who would have been allergic to spider venom will have a more severe systemic reaction.

Toxic to Animals

The toxicity of red-spotted ant-mimic spider is considered mild and is typically transferred via a bite. As adults, these organisms possess fangs capable of delivering venom. While larger animals such as humans and dogs may experience only minor discomfort or localized reactions, smaller creatures like rodents and insects could suffer more significantly due to their smaller body mass and distinct physiological reactions to toxins.

Rectangle
Bite Humans

Red-spotted ant-mimic spider typically refrain from biting humans and such behavior is rare. If they do bite, it's mainly in self-defense when they feel threatened. The bite method involves small fangs penetrating the skin, causing mild irritation or redness at most, but these bites are not medically significant and cause no serious consequences.
