Humans' reaction and the degree of irritation to a defensive urticating hair barrage can vary tremendously, based on the species in question. Some, such as those of the Chilean rose tarantula ( Grammastola rosea ) and the pinktoe tarantula ( Avicularia avicularia ), are fairly mild and innocuous to humans.
The bite from an Eastern tarantula is not fatal to a human, but can cause up to six hours of vomiting.The venom can cause death to a dog or cat within thirty minutes. [3] [8]In May 2010 a scientist living near Cooktown, Queensland, was bitten on her right index finger and experienced symptoms never reported before in research literature.
These urticating hairs can be harmful to humans. [9] Like all tarantulas, T. blondi spiders have fangs large enough (2–4 cm or 0.79–1.57 in) to break the skin of a human. They carry venom in their fangs and have been known to bite when threatened, but the venom is relatively harmless and its effects are comparable to those of a wasp's sting
The bites don't tend to appear in clusters but rather as individual bumps, possibly on different parts of uncovered skin. Some people have more severe reactions that cause a hive-like rash in the ...
A spider bite, also known as arachnidism, is an injury resulting from the bite of a spider. The effects of most bites are not serious. [1] Most bites result in mild symptoms around the area of the bite. [1] Rarely they may produce a necrotic skin wound or severe pain. [2]: 455 Most spiders do not cause bites that are of importance.

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
Black widows make irregular or asymmetric webs, Medline Plus says, and the spiders can bite people when humans bump into their webs. The spiders also typically stay within a few feet of ground level.
Old-world tarantulas, especially those indigenous to Asia, lack urticating hairs and may bite as a defensive mechanism. They are far less docile than new-world tarantulas, and are more likely to bite when provoked. Hobbyists report bites by Poecilotheria species, occasionally resulting in hospitalization. Symptoms include localized pain and ...
