Wolf Spiders are not considered highly venomous to humans. While their bite can be painful and cause some localized swelling, it is not typically life-threatening. In most cases, the symptoms of a wolf spider bite can be managed with basic first aid and do not require medical attention.
a wolf spider. they hurt but are not deadly to humans
A horned spider is not deadly to humans although the venom can cause necrosis.
No they are harmful to humans. They eat grasshoppers.
The two most deadly spiders to humans are black widow spiders and tarantula.
It really depends on the spider. Many Spiders actually aren't deadly or even poisonous to humans.
First of all the "camel spider" isn't really a spider; it's a spider kin called a solafugid (means "flees from the Sun," which it certainly does). Its venomous bite is painful, but not deadly, to humans. Stories about its anesthetic powers are not true.
Well, tarantula is the only one, except that their bite is not deadly to humans.
Although they can bite they are not poisoness or deadly. (Mythbusters proved it!)
it can make you very sick, but not that deadly
A spider with a brown oval mark on its back could potentially be a brown widow spider. Brown widows are related to black widows but have characteristic brown markings on their abdomens. It's always best to consult with an expert or use caution when identifying spiders to avoid potential harm.
Only a few species are seriously poisonous to humans. There are these few Spiders: black widow, African brown spider, bird spider, and if you ever see a spider with a violin shape on its back stay clear this spider can kill and is known for it. *Edit: The violin spider (or Brown Recluse, Loxosceles Reclusa, or Fiddleback spider) mentioned above is NOT deadly. It is difficult for doctors to diagnose spider bites, and the bite of this particular spider looks very similar to other serious conditions, so a lot of pictures/stories you see/hear about this spider being deadly are false. Though not deadly, this spider does cause very serious wounds and should be avoided. It is not aggressive.
