Jumping spiders are part of the family Salticidae and possess fangs that produce venom to subdue their prey. However, their venom is only effective against smaller insects and has no adverse effects on humans. These spiders are active hunters, preferring sunny conditions and using their incredible jumping abilities to move quickly and pounce on passing prey, such as moths, grasshoppers, and other small invertebrates.

Although venomous, jumping spiders pose no substantial threat to humans, as many people wonder if jumping spiders’ poisonous effects are dangerous. Their venom is not potent enough to cause any harm, and their bites are extremely rare. In fact, if you were bitten by a jumping spider, you would likely only experience mild discomfort, similar to a mosquito bite or less severe than a bee sting.

Identifying Jumping Spider Species

There are over 6,000 species of jumping spiders worldwide, with the bold jumping spider (Phidippus audax) being the most common species in North America. Adult jumping spiders range in size, typically measuring between 1/8-3/4” (4-18 mm). The bold jumping spider is one of the larger species, measuring up to 3/4” (18 mm) in size, and jumping spiders have a surprisingly long life span.

One of the most distinctive features of jumping spiders is their eye arrangement. They possess eight eyes arranged in three rows, with a very large middle pair in the front row. This allows them to have excellent vision, which they use to stalk and hunt their prey.

Jumping spiders have the following characteristics:

  • Dense hairs on their bodies
  • Relatively short legs compared to other spider species
  • Coloration varies, but most jumping spiders display black, brown, tan, or gray hues, often accompanied by pale markings.

Do Jumping Spiders Bite?

As previously noted, it’s uncommon for jumping spiders to bite humans and even when they do, it’s generally harmless. A jumping spider’s bite is not fatal but can cause mild pain and uneasiness. The venom present in its fangs may result in itching, swelling and other discomfort. The bite is generally similar to a mosquito bite and is unlikely to puncture the skin. If the bite does puncture the skin, the pain is comparable to that of a bee sting. These effects typically resolve on their own within a few hours and do not require medical attention.

While most individuals only experience mild symptoms after a jumping spider bite, there are rare cases where some might have an allergic reaction. In such cases, individuals might experience dizziness, nausea, or vomiting and should seek medical advice. However, these reactions are rare, and jumping spiders are not considered a threat to human health.

How to Treat a Jumping Spider Bite

If you’re bitten by a jumping spider, here are some straightforward steps to treat the bite at home. First, wash the spider bite location with soap and water to clean the area and prevent infection.

Next, to treat a mosquito bite, you can:

  • Apply a cold compress to the bite site to reduce swelling and discomfort
  • Take aspirin or acetaminophen to help relieve minor symptoms, such as pain and inflammation
  • Take antihistamines to reduce itching

Remember to monitor the jumping spider’s bite site and seek medical attention if spider bite symptoms worsen or if an allergic reaction is suspected. In most cases, though, a jumping spider bite will heal on its own without any complications.

Are Jumping Spiders Dangerous to Pets?

You may question whether jumping spiders present a danger to your pets. The good news is that jumping spiders are not dangerous to pets, and their venom is not potent enough to harm them. These spiders are not aggressive, and their bites are not detrimental to humans or animals.
