On the whole, a bite from a false widow will only have a mild effect on humans with bites from females typically resulting in more severe symptoms than from the male spiders.

Symptoms of a bite can include fever and intense pain.

Experts claim that the false widow species aren't usually aggressive towards humans but if they are caught in clothing, or trapped then they might lash out.

If you are bitten by a false widow spider then you must immediately wash the area with water and soap.

Then, apply bite spray or antiseptic cream to help prevent further infection.

If the symptoms get worse, then seek professional medical help as soon as possible.
