Insect Bites in Arizona: How to Identify and Treat Them
Arizona's warm climate makes it a haven for insects like mosquitoes, bees, wasps, and ants. If you spend any time outdoors in Arizona, there's a good chance you'll end up with a bug bite. While most insect bites cause only mild irritation, some can transmit diseases or cause a severe allergic reaction.
Knowing how to identify different insect bites can help you choose the right first aid treatment and know when to seek medical care. This article covers some of the most common bug bites Arizonans encounter and provides tips to relieve symptoms and prevent infections.
Mosquito Bites
Mosquitoes are one of the biggest nuisances in Arizona. Female mosquitoes bite humans and animals to acquire the protein needed to produce eggs. A mosquito pierces the skin with its long proboscis to withdraw blood.
Mosquito bites usually appear as small, round, pink bumps that fill with fluid and become itchy. Scratching the bites can break the skin and lead to infection. The bumps normally go away on their own within a few days.
While mosquito bites themselves are just annoying, some mosquitoes do transmit serious diseases like West Nile virus, malaria, dengue fever, and Zika. See a doctor promptly if you develop any flu-like symptoms after being bitten by mosquitoes.
Treatment for Mosquito Bites
To relieve mosquito bite itching and swelling:
- Wash the bite with soap and water to remove any saliva or dirt that could cause infection.
- Apply hydrocortisone cream or calamine lotion to reduce itching.
- Apply ice or a cold pack to numb the area and reduce swelling.
- Don't scratch the bites, as this can open them up to infection.
- If very itchy, take an oral antihistamine like Benadryl to reduce symptoms.
Chigger Bites
Chiggers are tiny red mites, usually found in grassy or wooded areas. They attach to the skin and inject digestive enzymes that break down skin cells. This causes small, red, intensely itchy bumps or welts.
Chigger bites usually occur around the ankles, waistband, armpits, or groin where clothing fits tightly. The mites fall off after a few hours or days, but the itching can persist for up to two weeks.
To ease discomfort from chigger bites:
- Take a warm soapy bath or apply a cold pack to soothe itching.
- Resist scratching as this can lead to infection.
- Apply aloe vera gel or hydrocortisone cream to reduce inflammation.
- Oral antihistamines like Benadryl can help control itching.
See a doctor if bites become infected, oozing pus or blood. Signs of infection include increased pain, swelling, redness, and warmth around the bite.
