Types of Venomous Spiders

Neurotoxic Venom Spiders

black-widow-spider-with-dime.jpgBlack widow spiders have neurotoxic venom that causes the release of the neurotrasmitter acetylcholine, which can lead to muscle contractions, pain, weakness, and in severe cases, adominal cramps, nausea, difficulty breathing and elevated blood pressure.  Abominal cramps from spider bites can imitate appendicitis or gall blatter problems and the chest pain has been mistaken for heart attack. In most cases, black widow spider bites are not life threatening (except rarely in small children or the elderly).  If possible, take the black widow spider specimin with you to the emergency room for indentification when you seek treatment for the spider bite.  There is no established treatment for black widow spider bite, exept for strong, narcotic-type, pain relievers.  In rare cases, antivenom may be used, but some people have stronger reactions to the antivenom than they do to the black widow spider bite.






Necroctic Venom Spiders

brown-recluse-spider-with-penny.jpgBrown recluse spiders, and to a lesser degree hobo spiders, have necrotic venon, that can cause skin ulcers, which can sometimes cause the skin and soft tissues to become gangrenous, decaying and slough off.  These ulcerous wounds often take months, sometime years, to heal. The medical community has no recognized treatment for brown recluse spider bites, although there has been a few case studies claiming success treating brown recluse bites with Cortizone to reduce inflammation and Nitroglycerin patches to draw fresh blood to the wound.







Spider Bites

Venomous spider bites are usually minor, but occationally can cause complications.  Some venomous spiders, particualarly brown reclulse spiders and to a lesser extent hobo spiders and black widow spiders, can cause necrosis with thier spider bites.   Necrosis is ulcerated skin that can decay and die.  Sometimes this leads to a small patch of dead skin, in rare cases it can cause severe gangrenous wounds and scaring.  

  • brown-recluse-spider-bite-after-sevdral-weeks.jpgbrown-recluse-spider-bite-3.jpgThe first symptoms of a spider bite are similar to a those from a bee sting and include pain and a burning sensation (although to some the pain is not noticed at first)
  • Within a few minutes of a spider bite it is common to notice a mild redness, itching, swelling, and sense of warmth.
  • With carful inspection, you may notice a tiny puncture wound or fang marks from a brown recluse or black widow spider bite.
  • A few hours after a black widow or brown recluse spider bite, some vitims notice a "bullseye" like pattern with a red spot surrounded by a ring of pink.

Most spider bites, including those from black widow or brown recluse spiders, do not progress beyond these symptoms, but some cause a more severe reaction.  More severe symptoms my include:

  • severe pain, muscle cramps
  • nausea, vomiting, fever

brown-recluse-spider-bite-6.jpgbrown-recluse-spider-bite-1-closeup.jpgNecrosis varies (in order of increasing severity):

  • tiny hard spot
  • blistering
  • lesion with bluish or grayish tint surrounding the redish tissue (the red-white-blue sign)
  • death of skin and fat below the skin
  • sunken, open, oozing, gangrenous wounds (relatively rare)

Identifcation of a necrotic spider bite from a brown recluse spider is difficult even for most physicians, this is why it is important to take the suspected spider for idenfication in a small clear jar or bag if possible.


It may be wise to have a Spider Bite First Aid Kit on hand!
