However, most bite victims suffer only local pain and bleeding, a few more have limited neurotoxic symptoms (tingling, racing heart, more widespread pain), and there have been several recorded bites by this spider producing severe symptoms requiring medical treatment. [37] There are no recorded human fatalities due to mouse spider bites.
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".

Treatment of bites may depend on the type of spider; thus, capture of the spider—either alive, or in a well-preserved condition, is useful. [33] [34] Treatment of spider bites includes washing the wound with soap and water and ice to reduce inflammation. [35]
They are known for their docile nature; if frightened they may fling hairs or run away, though this is rare. In very unique cases this spider may bite, though the venom is mild. While slings are more prone to burrowing, adults will usually find a hide instead of burrowing. Adults will usually stay out of their hides in an open area.
The spider biting apparatus is short and bites are only possible in experimental animals with pressure on the spider's back. Thus many bites occur when a spider is trapped in a shirt or pant sleeve. There is no commercial chemical test to determine if the venom is from a brown recluse. The bite itself is not usually painful. Many necrotic ...
An adult female of a Brachypelma species, showing a bald patch after kicking bristles off of her abdomen. After molting, the bristles will grow again. Not all urticating hair types are exhibited by each species of tarantula. Type II urticating hairs can be found in the genera Avicularia, Iridopelma and Pachistopelma (subfamily Aviculariinae).
