Black Widow vs. Brown Recluse Spider

Black widow vs. Brown recluse spider

The black widow and the brown recluse are the two most common venomous spiders in the U.S. They are usually found in warm climites like the southern states in dark places like an attic or a garage

Black Widow 
  • Venom affects the nerve system
  • Some people highly affected others not it depends
  • Symptoms usually start with 20-60 minutes after the bite. 
  • Symptoms are muscle cramps, abdominal pain, weakness, and tremor may occur. If you are highly affected are nausea, vomiting, faintness, dizziness, chest pain, and trouble breathing. 
  • five different specious know in the U.S
  • half an inch long body 
  • Southern- has a shiny belly with an hourglass on it 
  • Northern-line of red dots on its back (it can have red legs)(kinda creepy)
  • nocturnal like vampires which their bites do look like little tiny vampire bites
  • only female attack human when being bothered
  • minor bites recommend a hot bath because all you may have is muscle spasm
  • severe bites need medical care which may be treated with narcotics and antivenin
Brown Recluse 
  • venom more toxic than rattle snake
  • poison affects the cells and tissue
  • symptoms start to appear 2-8 hours after venom has been injected, severe itching, nausea, vomiting, fever, and muscle pain (myalgias).
  • legs one inch long
  • violin pattern on part where legs are attached
  • all bites are recommended to be seen by a doctor 
  • attack when they feel threatened (so would I)
  • six eyes which we can't see with our eyes
Both bites can be very serious meanwhile the Brown Recluse is more affective and more severe.

The black widows protein toxic affect the nerve system. Some people reactions are more server than others. Most of the time it is treated with narcotics and antivenin.

The brown recluse spider contains a venom with many enzymes which makes it really poisonous. It destroys the cell membrane uncovering the tissue and makes nasty looking wounds and can cause a hole in the flesh known as volcano lesion. The best thing to do if bitten by this spider go seek medical care.

(P.S I got chills through out all this research especially seeing some of the pictures)
