Giant huntsman spiders, known for their impressive size and swift movements, often spark curiosity and apprehension. These large arachnids, characterized by their long, flattened bodies and legs that can span up to 12 inches, are a frequent subject of inquiry regarding their potential to bite. Understanding their natural behaviors helps to demystify these creatures.
Do Giant Huntsman Spiders Bite?
Giant huntsman spiders possess fangs and can bite, but they generally do so only as a defensive measure. Their primary instinct is to flee rapidly, utilizing their speed and agility to escape perceived threats. They are not aggressive towards humans and bite only as a last resort, when cornered, trapped, or accidentally handled. For instance, if a spider is inadvertently pressed against skin or becomes entangled in clothing, it might bite in self-preservation. Encounters leading to bites are almost always accidental, stemming from unknowingly disturbing the spider in its hiding place.
What to Expect from a Bite
A giant huntsman spider bite is typically localized and not medically significant for humans, as their venom is relatively mild. Common symptoms include immediate, sharp pain at the bite site, followed by mild swelling, redness, and a throbbing sensation. Some individuals might experience minor systemic reactions such as a headache, nausea, or mild palpitations, though these are rare and usually subside quickly. To manage a bite, clean the wound thoroughly with soap and water and apply a cold pack to reduce swelling and pain. Seek medical attention if symptoms worsen, if there are signs of an allergic reaction like difficulty breathing or widespread rash, or if signs of infection, such as increasing redness, pus, or fever, develop.
Giant Huntsman Behavior and Habitat
Giant huntsman spiders are primarily nocturnal hunters, meaning they are most active during the night. Unlike many other spiders, they do not construct webs to catch prey; instead, they actively stalk and chase down insects and other invertebrates. Their flattened body shape allows them to squeeze into tight spaces, making them adept at hiding under loose bark, in rock crevices, or within dense foliage during daylight hours. These spiders often seek shelter in human dwellings, especially in warmer climates, finding dark, secluded spots like behind curtains, under furniture, or inside shoes. To minimize accidental encounters, shake out shoes, clothing, and towels before use, particularly if they have been left on the floor, and exercise caution when moving undisturbed items like boxes or woodpiles.
