4.Red Back Spider -- Very closely related to the Black Widow and quite similar in appearance. The Red Back has a comparable strength of poison to it’s cousin but these spiders are not as widely spread. A native of Australia the Red Back spider is quite commonly seen around out houses, basements, closets and around bins. Again this spider rarely causes death when it bites humans but it has been known on rare occasions to produce fatalities. These spiders are very recognisable by the red stripe they have running down the length of their backs, for this reason they are often called jockey spiders. So again not a nice spider to bump into as it does have a nasty batch a venom and can still be classsed as a very poisonous spider.
5.Brown Recluse Spider -- Last but by no means least on our list is the Brown Recluse spider. Native to north America these spiders are quite shy as suggested by the name. However if you disturb one of these and it feels in danger it will not hesitate to bite. The poison delivered by the brown recluse is very rarely fatal, however it can cause a wide range of symptoms ranging from paralysis to vomiting. Often known as the violin spider or fiddleback spider, they can sometimes be found inhabiting cellars, barns, closets, wood piles and anywhere else dry and warm. Although this type of spider only grows to about 5cm but is still one to be avoided if at all possible due to its nasty venom and poisonous reputation.
