Are most spiders poisonous?
The majority of the 3,000 spiders in the United States aren’t poisonous. Even if most spiders did bite, their fangs are too small or weak to puncture human skin. Their bites may leave itchy, red wounds that heal within a week or so.
The spiders that do manage to bite through our skin and insert toxic venom can cause serious health complications. Read on to learn what spider bites look like, what varieties of spider leave certain bites, and how to treat spider bites.
What do spider bites look like?
Identifying a spider bite is easiest if you saw the spider that bit you, but it’s possible that you won’t notice the wound until hours later. Look for things like swelling, a red welt, skin damage, and any troubling symptoms that accompany the bite.
Other possible symptoms that accompany spider bites include:
- itching or rash
- pain around the area of the bite
- muscle pain or cramping
- blister that’s red or purple in color
- difficulty breathing
- nausea and vomiting
- anxiety or restlessness
- swollen lymph glands
- high blood pressure
Spider bites often take longer to heal than other insect bites, and they may affect skin tissues. It’s important to keep the bite clean to reduce the risk of infection.
