What to Do About Arizona Spider Bites

In Arizona, the only spiders with dangerous venom are the black widow and the brown recluse. While most spiders are venomous, most of them will only cause swelling at the area surrounding the bite. The exception of course is if you have an allergic reaction to that particular spider’s venom. The non-dangerous spiders indigenous to Arizona include funnel web spiders, giant crab spiders, green lynx spiders, labyrinth spiders, tarantulas, and sun spiders. These spiders are actually quite useful to have around your home as they eat annoying pests, sometimes even other spiders.

What To Do About Black Widow Spider Bites

black widow spiderThe black widow spider’s venom can be lethal to humans, however, it is rare for the spider to inject a fatal dose. More frequently the bite will cause nausea, cramping, and dizziness. Most importantly if a person who has been bitten begins to have trouble breathing or is showing signs of shock, call for emergency medical help immediately. Even if the bite victim is functional, it is still necessary to go to the emergency room or to call your health care provider. On the way to the health care provider apply ice to the area to reduce swelling and help manage the pain. If the victim is showing severe reactions such as high blood pressure or intense cramping they may need antivenin or to be admitted to the hospital for the night. The health care provider will examine and clean the wound and may have to give the person a booster or tetanus shot.

What To Do About Brown Recluse Spider Bites

The most common reaction to a bite inflicted by a brown recluse is a spreading sore on and around the area of the bite itself. If this sore goes untreated it can potentially cause permanent tissue damage. Prompt treatment of a brown recluse bite is of utmost importance, especially for children. Gently wash the area and apply an antibacterial ointment to the injection site. Then ice and elevate the area if possible to reduce and prevent excessive swelling. Call your health care provider as soon as possible. Your healthcare provider is likely to prescribe an antibiotic to prevent infection and acetaminophen or ibuprofen for pain relief. On some occasions hospitalization or surgery could become necessary. The bite area could take up to 8 weeks to fully heal.

Why Treating Spider Bites Is Important

Bites from other Arizona spiders can also be mildly dangerous if not treated properly, but they are not lethal. When treating these bites it is important to wash the affected area gently with soap and water and to ice the area to reduce pain and swelling. Some numbness may occur from the bites of funnel web spiders. Other symptoms may include difficulty breathing, and double vision. Visiting your healthcare provider is still important specifically for children, however the danger from these bites are minimal. The bites of the giant crab spider, green lynx spider, labyrinth spider, sun spiders, and tarantulas, while quite painful are not dangerous to humans.
