Spider bites, especially from venomous species, can cause a range of symptoms,
from mild irritation to severe medical complications. The most dangerous spider bites
come from species like the Black Widow, Brown Recluse, and Funnel-Web spiders.

Common Symptoms:
A venomous spider bite typically begins with a sharp pain or a stinging sensation at
the site of the bite. This can be followed by redness, swelling, and itching. In more
severe cases, the venom can cause muscle pain, cramping, sweating, nausea, and,
in rare cases, systemic symptoms like fever or chills.

Dangerous Species and Their Effects:
– Black Widow: Known for its potent neurotoxic venom, a bite can cause intense
muscle pain, abdominal cramping, and in rare cases, life-threatening symptoms.
– Brown Recluse: This spider’s venom can lead to necrosis (tissue death) around the
bite site, potentially causing deep ulcers and infections.
– Funnel-Web Spiders (primarily in Australia): Their bites can be fatal if left untreated
due to the strong neurotoxins they inject, causing rapid muscle twitching, elevated
heart rate, and respiratory distress.

Treatment:

For any suspected venomous spider bite, it’s important to seek medical attention
promptly. Cleaning the bite site, applying ice, and keeping the affected limb elevated
can help minimize symptoms. Antivenom is available for some species, like the
Funnel-Web and Black Widow, and can be life-saving in severe cases.

Prevention through avoiding spider-prone areas and wearing protective clothing can
reduce the risk of venomous spider bites.
