Venom poisoning caused by Latrodectus mactans

Latrodectus mactans, commonly known as the black widow spider, is one of the most feared spiders in many countries because of its venomous bite. The bite of these spiders is very painful and can even send some people into shock. However, the poison is not usually fatal in humans unless they are allergic.

The venom of Latrodectus mactans is neurotoxic, which means it affects the nervous system. It is rarely fatal in mammals but can be deadly to small animals like mice. In humans, the venom can cause nausea, vomiting, and muscle pain. In severe cases, the venom can cause chest tightness, difficulty breathing, and seizures. In rare cases it can even lead to coma or death.

Treatment for Latrodectus mactans venom poisoning is usually done with antivenom or with medications such as acetaminophen or ibuprofen to relieve pain and inflammation. In some cases, people who have been bitten may need to be hospitalized and monitored in order to be sure that the venom is not going to have any long-term effects. It is important to seek medical attention as soon as possible after a bite.

  • Wear shoes outdoors and shake them out before putting them on
  • Clean up cluttered areas that may provide shelter for spiders;e
  • Inspect and repair any potential entry points into dwellings or structures;
