The venom contains excitatory neurotoxins (alpha-latrotoxins), which overstimulate the nerves. Bites usually deliver only small amounts of venom. Symptoms can include intense pain at the bite, sweating, rapid breathing, a faster heart rate, swollen eyelids, salivation, stiff and painful abdominal muscles, nausea, vomiting and blurred sight. Some cases have also involved muscle spasms, fever and chills, which are common symptoms of latrodectism (the illness caused by black widow venom).1

In a case in the Brazilian state of Amazonas, the victim had muscle spasms, fever, chills and heavy sweating.1
