Understanding Wasps and Hornets in Arizona
Wasps and hornets are common sights in Arizona, especially during the warmer summer months. While they play an important role in pest control and pollination, their painful stings can be dangerous for those who are allergic.
Common Types of Wasps and Hornets in Arizona
Some of the most common wasps and hornets found in Arizona include:
- Paper wasps - Recognizable by their umbrellashaped nests made of paper.
- Yellowjackets - Black and yellow striped wasps that build nests in holes in the ground or cavities.
- Tarantula hawks - Large blue-black wasps that paralyze tarantulas as food for their larvae.
- Bald-faced hornets - Black and white hornets that build football-sized nests in trees and shrubs.
The Benefits of Wasps and Hornets
While their stings can be a nuisance, wasps and hornets are beneficial in the following ways:
- They are predators of pest insects like flies, caterpillars, and spiders.
- They pollinate flowers as they collect nectar and pollen.
- Their presence indicates a healthy local ecosystem.
What to Do If You Get Stung
If a wasp or hornet stings you, there are a few key steps to take:
Remove the Stinger
Carefully scrape the stinger out with your fingernail or a credit card. Don't squeeze the stinger or use tweezers as this may release more venom.
Wash the Area
Wash the sting area with soap and water to clean away toxins and debris. This can help prevent infection.
Apply a Cold Compress
A cold compress or ice pack can help ease swelling, inflammation, and itchiness caused by the sting.
Use a Topical Remedy
Home treatments like calamine lotion, baking soda paste, or aloe vera gel can further soothe skin reactions at the site of the sting.
Take Oral Antihistamines
Over-the-counter oral antihistamines like Benadryl can counteract allergic reactions and reduce overall discomfort.
Signs of an Allergic Reaction
In rare cases, wasp or hornet stings can cause severe, life-threatening allergic reactions. Seek emergency care if you experience:
- Hives or rash over much of the body
- Swelling away from the sting site
- Tightness in the chest or difficulty breathing
- Dizziness, confusion, nausea, or other signs of shock
Carry an EpiPen
If you have a known wasp or hornet allergy, always have auto-injectable epinephrine (EpiPen) available when outdoors. An EpiPen can counteract dangerous allergic reactions.
Avoiding Wasps and Hornets
You can take steps to avoid unwanted encounters with wasps and hornets in Arizona:
Eliminate Food Sources
Clean up fallen, rotting fruit, nectar spills, trash containers, and other food waste that can attract them.
Avoid Nests
Watch out for the umbrellashaped paper nests of paper wasps and the football-sized gray nests of bald-faced hornets in bushes, trees, and building overhangs.
Stay Calm Around Wasps
Don't swat at wasps or make sudden movements, as this can threaten them and prompt stinging. Move slowly away from them.
Seal Up Entry Points on Your Home
Block holes and cracks around rooflines, vents, windows, and doors to prevent wasps from entering and nesting in your home.
Use Protective Clothing When Hiking
Wear light-colored long sleeves and pants to protect skin from stings. Tuck pants into closed shoes or boots.
Professional Wasp and Hornet Removal
If you discover a large wasp or hornet nest on your property, don't try removing it yourself. Contact a licensed exterminator to safely eliminate the nest and occupants.
Why Hire a Professional?
Attempting to remove a nest puts you at significant risk of multiple stings. Professionals have protective gear, wasp-specific insecticides, and knowledge of removal techniques to mitigate dangers.
Removal Techniques
Exterminators may carefully apply a liquid or dust insecticide directly into the nest. They may also remove the entire nest structure if possible. Treatment is usually done at night when wasps are less active.
Prevent Nest Rebuilding
After old nests are removed, exterminators can apply residual insecticides around the area to prevent wasps from rebuilding in the same locations.
Dealing with pesky stinging insects is simply part of life in Arizona. Understanding the right ways to treat stings, recognize allergic reactions, and control wasp populations can help you steer clear of problems.
FAQs
What are the most dangerous types of wasps in Arizona?
Tarantula hawks and bald-faced hornets likely pose the biggest danger. Tarantula hawks paralyze tarantulas to feed their larvae and their stings are incredibly painful. Bald-faced hornets are very aggressive and repeatedly sting perceived threats.
Are wasp and hornet stings more dangerous than bee stings?
Wasp and hornet stings are not necessarily more venomous than bee stings, but they can sting repeatedly whereas bees die shortly after stinging once. This means more venom can enter the body, provoking a more severe reaction.
Can wasp/hornet stings cause long-term health issues?
For those severely allergic, one or a few stings can be fatal. Survivors of such reactions may develop venom-specific antibodies and experience increasingly dangerous allergic responses with future stings.
What should I avoid doing if stung by a wasp/hornet?
Avoid squeezing the stinger, using tweezers to remove it, or using irritating topical treatments like rubbing alcohol. These actions can worsen venom injection and skin reactions. Let the stinger remain until it releases on its own.
How can I make my yard less attractive to wasps and hornets?
Eliminate standing water, properly dispose of food waste in closed containers, clean up fallen and rotting fruit, repair leaks around home fixtures, and caulk up holes and cracks where they could nest.
