Facts you need to know about Spiders




It is true that all spiders, by their definition, posses a pair of fangs through which they inject venom. And it probably doesn’t help their cause that they feed by turning their prey’s insides to liquid and then sucking it up.

Below are 10 facts about spiders

  1. Hobo Spider (Tegenaria agrestis)

The actual danger the hobo spider presents to humans is somewhat debatable. It has been proven to deliver quite serious bites to lab animals and there are many alleged cases of bites from these spiders causing necrosis, similar, but less severe than that observed in brown recluse bites. These bites cause an open wound which may take many weeks to heal.

2. Camel Spider (Solifugae)

The camel spider really is the stuff of nightmares, the biggest is the Egyptian giant solpugid.they look so fierce and grow so big. . Solifuges can inflict a painful bite but they are not venomous.

  1. Yellow Sac Spider (Cheiracanthium)

    A Yellow Sac Spider (Cheiracanthium mildei) roams the kitchen in a Chicago-area home. Frequently found indoors, the Yellow Sac Spider was introduced to the U.S. from Europe in the 1940s. The spider is capable of causing a painful bite; however, according to the Spider Myths Website, the spider has been falsely accused of causing necrotic lesions (bite symptoms of the truly dangerous Brown Recluse spider).

Small and innocuous in appearance   but capable of delivering quite a nasty bite, the yellow sac spider is one to avoid. Bites are characterized by an initial stinging pain followed by redness and swelling which can develop into a blister or sore.

Symptoms include general pain and swelling spreading from the affected area, abdominal cramps, nausea and sweating to name a few. This condition occurs in around half of bites and was often fatal in the very old and young before anti venom became available.

8.Brown Recluse / Chilean Recluse (Loxosceles)

They are flesh-eater and  usually mild, can result in a condition known as Loxoscelism. In these severe cases the area around the bite begins to die and a deep open sore is formed.
