Color and Markings

Velvety gray, black, brown, white, or iridescent hues cloak jumping spiders. Some dazzle with metallic greens or bold patterns. This camouflage helps them hide in vegetation while huntingand startles humans who discover the well-disguised crawlers!

Habits and Habitats

Diurnal creatures, jumping spiders actively roam during daytime hours. Expect to find them prowling gardens, forests, grassy fields, and deserts. Indoors, basements, sheds, and homes offer refuge too. They often frequent sunny window sills while capturing stray flies or moths.

Jumping spiders possess venom used to paralyze insects before feeding. But spider bites in humans almost never occur from these mini acrobatic predators. Heres why tiny spider fangs fail to break our skin.

Tiny Fangs and Mouthparts

A jumping spiders fangs measure less than 1/16th of an inch. Too small and weak to pierce human skin, the spider would sooner injure itself trying to bite you. Instead, jumping spiders administer venom through fangs mostly inserting into other invertebrates with soft exoskeletonsnot dense epidermal layers protecting humans.

First Aid for Spider Bites

Most spider bites require little intervention beyond basic first aid to clean the wound. Follow these tips if you suspect a venomous spider bite while seeking medical care as needed.

Wash Bite Area

Use mild soap and warm water to gently flush the bite. This removes lingering venom and bacteria from broken skin. Avoid harsh scrubbing that further aggravates swelling.

Apply Cold Pack

Chilling the bite with cold compresses or ice bags reduces inflammation and eases painful swelling. Wrap ice to avoid freezing skin. Limit cold therapy sessions to 10-20 minutes.

Elevate Bitten Limb

Lifting arms or legs above heart level also helps drain swelling. Raise the affected limb for 10-15 minutes a few times daily after that initial cold compress.

Watch for Infection Risk

Check the bite in following days. Escalating redness, skin hot to the touch and pus signal possible infection needing antibiotics. Otherwise keep it simply bandaged while healing.
