Spiders are either loved or hated by the world's population. We
appreciate them for their ability to catch other pests, kill them and
eat them, but at the same time, there's that "gross-out" factor that
many people cannot stand to have. Whether the spiders are small or
large, they bring chills to some and celebration to others. They are
found in and outside of the home and can even be poisonous. Here is a
short list of the ten most poisonous spiders found in the United States.
1. Brown Recluse Spider - found across the United States, predominantly in the South. Venom from this spider can cause injuries of tissue loss and necrosis.
2. Black Widow Spider - Found outdoors and in sheds and cluttered areas in basements and crawl spaces. Bites can cause headaches, nausea, vomiting, hypertension and abdominal pain. There were anti-venoms developed in 1956 for bites from these spiders.
3. Hobo Spider- Normally found in some of the north western states, this spider is usually found at ground level and below (in basements). Bites will blister and break open.
Symptoms include headache, nausea, fatigue, weakness, temporary memory loss, and even vision impairment.
4. Grass Spider - Found mostly in the Pacific Northwest, these spiders have a low risk to humans.
5. Female Mouse Spider - Both the male and female mouse spiders normally won't bite unless provoked. Male spiders will tend to bite before the female, and their fangs are rather large and produce a very painful bite. It's important to seek medical attention immediately. These spiders are ground dwellers and burrow up to 3 feet into the ground.
6. Male Mouse Spider - Can be found in both coastal and drier habitats. Symptoms include tingling around the mouth and tongue, facial muscle twitching,nausea, vomiting, profuse sweating,salivation and shortness of breath.
7. Black House Spider - While not lethal, black house spiders' bites are poisonous. People who have been bitten have experienced pain, sweating, muscular pains, headaches, and vomiting. First aid should be sought immediately.
8. Wolf Spider - Like the Black House Spider, the wolf spider is poisonous, but not lethal. If provoked, the spider will bite freely. If a child or elder is bit, seek medical attention immediately.
9. Female Trap-door spider - Trap door spiders present a non-toxic bit to humans and aren't very aggressive. They rarely bite, but if so, it can be very painful.
10. Garden Orb-weaving spider - These spiders present a non-toxic venom to humans. They rarely bite, and can be found in garden areas around the home. Their webs can be 6 feet or more in size and can be found between buildings or shrubs.
