5 Deadly Spiders to Avoid

Oh What a Tangled Web We Weave:

Sometimes we can be afraid of some of the smallest of things. However, there are some very small creatures, like the spider, that tend to raise the blood pressure of many individuals. Below is an overview of some of the most deadly spiders that we share this planet with. 


5 Deadly Spiders to Avoid:


1. If you are in Australia, beware of the Redback. Similar looking to the North American Black Widow, this species comes with a venom that is highly toxic to the neurosystem. The females are blacker than the males and their back is colored with red and orange stripes.

2. Another Australian resident is the Funnel-Web spider. The male for this larger specimen is the one who tends to attack. Standing on their hind legs and exposing their fangs, these glossy black or brown colored arachnids have a mean bite. Neurotoxic venom is its weapon.

3. Popular in North America, the Brown Recluse is not bigger than a penny but can cause some disturbing health issues. The body is shaped similar to that of a violin. The bite doesn’t hurt more than a mosquito’s but the venom injected into the victim can cause ulcers or even, in time, cause the flesh to rot.

4. Another resident that North Americans tend to not have around is the Black Widow. This glossy black creature has a red colored hourglass on its abdomen and its bite leaves more to be desired. After a bite has been given, there are two very visible holes left in the skin from the spider’s fangs. Neurotoxins injected can cause abdominal and back pain and cramps to even death of left untreated.

5. Moving to Central and South America, the Brazillian Wandering or Banana spider is found. If threatened, this spider raises its front legs and then “dances” from side to side. The results of a bite from this somewhat large brown spider can cause a number of medical issues similar to those of the Black Widows. Living in darker spaces, but closer proximately to humans than other spider species, this one is successful with 9 out of 10 poisonous bites.

Top 4 North America’s Most Venomous Spiders:


1. As referenced above, the Recluse is a top contender in the venomous community. However, of all the Recluse family, the Brown Recluse is indeed the most venomous. Found from coast to coast, measuring between ¼ to ¾ of an inch the Recluse uses 6 eyes (versus the standard 8) to move about. This is a spider that only bites when it feels threatened.

2. Found all over the world, the Widow family is extensive. Typically about ½ of inch in length, its shiny black body and orange/red hourglass is a “dead” giveaway to what type of spider this one is. To make matters worse, there are some widows that only have a small dot on their abdomen. Small, dark crevices are simply places to stay away from. With toxic venom 15 more times powerful than the rattlesnake, you don’t want to purposefully have a run in with one of these guys. Members of this family include the Red Widow and Grey Widow.

3. Hanging out in the Western United States and some parts of southwestern Canada, the Hobo spider can be found. The body can be between 1/3 and 2/3 of an inch in length while its legs can have a span up to 2 inches in length. The abdomen reflects a chevron or herringbone pattern and females have a rounder and larger abdomen than the males.

Webs are built in a horizontal fashion and prefer to stay closer to the ground. A bite is painless; however, redness at the bite site is followed by a blister which will then break open after about 24 hours. Symptoms can include severe, long lasting headaches along with weakness, nausea and even temporary memory loss.

4. The Yellow Sac or Black-Footed spider is typically found on the Northern continent. This 8-legged creature can be a pale yellow to a greenish, pinkish or even a tan color but can vary based on what its last meal was. The area of the body that holds the fangs will be black. Being nocturnal, activity (including bites) generally happens at night. Although their venom isn’t as toxic as some other spiders, bites leave symptoms at the site of skin irritations and pain.
