Do False Widow Spiders Bite

Spiders bite when they feel threatened or when they are pressed against the skin during handling. Bites from false widows are not common in most households and many routine activities do not lead to contact. They can occur if a person places a hand into a space where a spider rests and does not notice the creature.

If a bite happens the immediate discomfort is usually mild and localized. Some people may notice redness swelling and tenderness around the bite site. In rare cases a more noticeable reaction is possible but it remains uncommon in many cases.

Venom and Potential Health Effects
