Most spiders aren't dangerous to humans, even though almost all have venom; truly non-venomous spiders are rare (like Uloboridae), but many common ones like Huntsmen, Wolf spiders, Orb-weavers, and Black House Spiders have mild venom, are non-aggressive, and are beneficial, with their bites causing little harm, making them harmless for most people, notes this Quora page and this Facebook page.
Jumping spider pet
Some people keep jumping spiders as pets. Many species have beautiful coloration. They are one of the most intelligent and friendly spiders. They can be fascinating to watch and when handled gently, there's very little risk of being bitten.
The best beginner spider would be a tarantula such as the Chilean rose, Mexican Redleg, or Costa Rican Zebra. These species aren't terribly venomous and are pretty docile when compared with some other tarantulas (their venom is comparable to bee venom).

Not-so-scary Spiders
You should never squish a spider because it can release dozens of baby spiders if it's a mother carrying eggs, attract pests with released pheromones, cause allergic reactions from its internal fluids, leave stains and odors, and you'd be killing a beneficial predator that controls other insect populations. Most spiders are harmless to humans, and squishing them can backfire, worsening pest problems or causing messes.
While there's no single "Top 1," the Sydney Funnel-web Spider (Atrax robustus) from Australia is often cited as the world's most dangerous due to its potent, primate-specific venom, aggressive nature, and fast-acting effects, capable of killing a human quickly, though fatalities are rare now due to antivenom. The Brazilian Wandering Spider (Phoneutria species) also ranks high for potent venom and aggression, but the Sydney funnel-web's impact on humans makes it a top contender.
While most house spiders are generally nocturnal, they are not usually attracted to sleeping humans. Spiders have an incredible ability that allows them to know exactly how big and how far objects are from them.

Spiders really don't like strong scents such as citrus, peppermint, tea-tree, lavender, rose or cinnamon. Add 15 to 20 drops of your chosen essential oil or a couple of capfuls of Zoflora fragrance to a spray bottle filled with water, and spritz around the house.
Use a vacuum cleaner if you need to kill one or just a few spiders efficiently. Spider physiology is not strong enough to withstand the suction of most vacuum cleaners. The force will throw them against the tube or inner chamber of the machine, killing them almost instantly.
They mostly use sight and vibrations to hunt and navigate. However, they are attracted to environments where their prey may be present. These insects are often attracted to sweet or pungent odors, so areas with strong food or garbage scents could indirectly attract spiders.
The answer is generally yes, many spiders are afraid of people, but not necessarily right away. When considering spider removal in the house, homeowners should consider some of the factors that go into whether or not spiders fear humans.
