Two disadvantages of spiders are their venomous bites, which can be harmful or even deadly to humans, and their ability to create unsightly webs in indoor spaces. Additionally, some people have arachnophobia, a fear of spiders, which can cause anxiety and distress.
All spiders are venomous to some degree, but not all are harmful to humans. Jumping spiders can give you a painful bite, but the effects are more like a bee sting than anything else, and most people get over the effects of the venom within a day or two.
All spiders (with one or two exceptions) are venomous, it is necessary for them to feed, as they cannot eat solid food. There are two groups of spider which are commonly referred to as 'crab spiders', one is the Genus Sicarius, whose venom is dangerous to humans. The unrelated spider family Thomisidae is the other group, these are not dangerous to humans.
Most spiders are small, inconspicuous arthropods which are harmless to humans. Their beneficial role in keeping insect populations in check far outweighs the hazard posed by the few spiders that occasionally bite humans. Very few of the nearly 900 species of spiders in Texas can hurt people. Only two groups--recluse spiders and widow spiders-- are considered poisonous to humans. Tarantulas, jumping spiders, wolf spiders and some other spiders worry people who mistakenly believe they are seriously poisonous. Although these spiders are often large, hairy and formidable-looking, their bite is typically less harmful than a bee sting. People who are extremely allergic to spider venom, though, react severely to any spider bite. Many people have a phobia of spiders. However, knowing how to distinguish harmless from dangerous spiders, how to prevent them from entering the home and how to control those that do enter can prevent needless concern and reduce the chances of harm to humans.

Red-back & Funnel web.
Well I live in the USA in Alabama, the south seems to get alot of venomous things, but we have two really deadly spiders, that I know of, we have the Wolf Spider, and the Brown Racluse.

to my understanding, most if not all spiders are venomous but the vast majority of them are not dangerous to humans, although they will most likely cause some pain. most household spiders are completely harmless. the ones you need to watch out for depend on where it is you live but assuming you live in the USA the first two that come to mind in terms of what you might find in your home are the black widow and the brown recluse, both of which are potentially deadly if the bite is not treated soon enough. if you want to know what they look like just do a google image search.
Worst, two of most recluse spiders are found in Peru, the Chilean and the Gaucho.

all spiders are venomous. but there are only two spiders in north America that have venom that can seriously harm a human, the black widow, and brown recluse, aka violin spider, and fiddleback. the green lynx spider is not venomous to humans though, but it does hurt to get bit!

Well, This is a stupid question. The orange Tarantula I own is a Pterinochilus murinus, and it's very fast and bites without warning. But? What a stupid, stupid question. Can you think to yourself maybe.. "Are black dogs nice?"
Two poisonous spiders found in Australia are the Redback spider (Latrodectus hasseltii) and the Funnel-web spider (Atrax and Hadronyche species). Both spiders can deliver a potentially dangerous venomous bite to humans.
