VENOM TOXICITY - the bite of Daddy long-legs spider is not considered dangerous to human health. They are a non-aggressive group of spiders; their fangs very small but may pierce human skin. Area of distribution - Australia-wide.
They do not have venom glands, fangs or any other mechanism for chemically subduing their food. Therefore, they do not have injectable toxins. Some have defensive secretions that might be toxic to small animals if ingested.
Daddy long legs, also known as cellar spiders, contain venom and possess fangs, but there has been no evidence of their fangs being too short to cut through human skin or of their venoms being deadly and poisonous to humans. In reality, daddy long legs are not poisonous or dangerous to humans and are not known to bite.
Although the daddy-long-legs is one of Australia's most common and frequently seen spiders, it isn't native to Australia and was accidentally introduced to this country from Europe many years ago.
You could even say that daddy longlegs are one of the most benign insects around. They don't bite or poison anyone, and they are not garden or farm pests. They are just gentle, gawky bugs that like nothing better than meeting up together and having a communal gathering.
Because the “daddy longlegs” eats pests, it can be considered beneficial, but when enough beneficial arachnids get together, they become a nuisance. You should sweep them away with a broom, and look for other pests that may have attracted them in the first place.
The daddy long legs spider bite
The spider was able to pierce the skin, but the person that was bitten reported a mild burning sensation at the bite location that lasted only a few seconds. So basically, the daddy long legs spider is harmless, but that does not mean that we want these creepy crawlers around the home.
In summary, on current evidence the most dangerous spiders in the world are funnel-web spiders (Atrax and Hadronyche species), Redback Spiders and their relations (Latrodectus species), Banana Spiders (Phoneutria species) and Recluse Spiders (Loxosceles species).
Banana spiders may look intimidating, but they're actually timid and not considered dangerous. Though they aren't poisonous, their bite can be painful.
If you look closely, the male has a square-ended body, but the female has a long, sharp-ended body - this stinger-like 'tail' is her ovipositor, which she uses to lay her eggs in the ground.
The Opilionids are true daddy longlegs, but do not have a set of fangs or venom glands to go along. While they do secrete a liquid as a defense, they are only poisonous to their predators when ingested. However, they do not bite and are NOT poisonous to humans.

The Sydney funnelweb spider Atrax robustus, is considered to be the world's most dangerous spider. It is found within a 100 km diameter circle around Sydney. No deaths have occurred since the advent of an antivenom in 1981.
In Australia they are only found in the southeastern part of the country, from South Australia to Queensland via Victoria, New South Wales and Tasmania. You won't find them in the dry and arid zones. On the other hand, huntsman and wolf-spiders are found all over the country.
Sometimes when we get too close or disturb them, they treat us like they would treat any predator. Many spiders have threat displays intended to scare off predators, such as rearing up or lunging. Biting in self-defence is another strategy that spiders can use when they are afraid for their lives.
The common name, daddy-longlegs, likely came about because of their small oval body and long legs, and the name harvestman because they are most often seen in large numbers in the fall around harvest time.
Despite the rumors, daddy longlegs are not venomous and do not bite humans. However, they are hunters and come out at night to catch their prey.
Yet despite their apparent harmlessness, Daddy-long-legs have little trouble catching, wrapping and killing much larger Huntsman spiders. They have even been known to catch Redback spiders and Funnel-web spiders, both of which are far larger and more toxic than the Daddy-long-legs.
