Itchy Mite Bites: What You Need to Know

Itchy Mite Bites: What You Need to Know

Mite bites have been increasingly reported in some areas, causing itching, redness, and discomfort for those affected. Although these bites are usually harmless, they can be annoying and unexpected. Thankfully, they are treatable and you can even reduce your risk of getting bit.

Why are mite bites occurring after the emergence of cicadas?

Mites, also known as Trombiculidae or chiggers, are tiny arachnids that typically feed on plants, small insects, and larvae. They become especially active when cicadas emerge in large numbers. This increase in mite activity is usually tied to the periodic emergence of cicadas, such as the 13-year or 17-year cicada cycles seen in certain regions of the United States. When cicadas hatch in massive swarms, mites thrive because they have an abundance of food sources available.

Mites latch onto cicadas and other insects for a brief period, but occasionally, they can find their way onto humans. While they don’t actually bite or burrow into the skin, their saliva can cause intense irritation when it interacts with human skin, leading to itching and redness. These reactions can be particularly troublesome in areas with high cicada populations.

What to know about itchy mite bites

It’s important to understand that cicada mite bites are typically harmless, even though they can be bothersome. Mites do not transmit diseases to humans, and their bites do not pose long-term health risks. However, those with sensitive skin or allergies might experience more intense reactions, which can sometimes resemble small blisters or welts.

How to treat cicada mite bites

While mite bites are not dangerous, they can be uncomfortable. Thankfully, treating mite bites is not much different than treating a regular itchy area. Following are effective strategies to find itch relief.

1. Clean the area: As soon as you notice a bite, wash the affected area with soap and water to remove any remaining mites and reduce further irritation. 
2. Apply creams or lotions: Over-the-counter hydrocortisone cream or calamine lotion can help relieve itching and reduce inflammation. Follow the directions on the packaging. 
3. Take antihistamines: Oral antihistamines can reduce itching and swelling, especially if you have multiple bites. Follow dosing instructions or consult a healthcare provider if needed. 
4. Use cold compresses: For a more holistic approach, use a cold compress or ice pack to reduce swelling and numb the area, providing temporary relief from itching.

It's essential to avoid scratching the bites, even if they are very itchy, as this can lead to secondary infections. 
If symptoms persist or show signs of infection (such as increased redness, pus, or pain), seek medical advice from a healthcare professional.

How to decrease your risk for mite bites

There are various treatments for mite bites, but it's best to prevent them from occurring in the first place. There are practical tips you can take to decrease your risk, including:

• Wear protective clothing: When spending time outdoors, especially in areas with high cicada activity, wear long sleeves, long pants, and closed-toe shoes. If possible, wear light clothing made for the summer to avoid overheating.
• Spray your foliage with permethrin: If you want to avoid cicadas all together, and you have trees and/or bushes near your home, spray them with permethrin to kill the mites. However, this is a toxin so you should avoid using it if you have pets or kids that spend time outside.
• Avoid sitting on the ground: Mites are often found in grassy and wooded areas. Avoid sitting directly on the ground or in thick vegetation, as this is where mites are most likely to come into contact with you.
• Shower after outdoor activities: Taking a shower and changing clothes immediately after outdoor activities can help wash away any mites before they have a chance to bite.
• Keep lawns and gardens well-maintained: Keeping grass mowed short and reducing leaf litter and dense vegetation around your home can help decrease mite populations in your immediate surroundings.

When to see a doctor for cicada mite bites

As mentioned, these bites are almost always harmless, although irritating. You should see a doctor if:

• The bite area shows signs of infection, such as severe redness, pus, or swelling that worsens over time.
• You experience an allergic reaction, such as hives, difficulty breathing, or swelling of the face or lips.
• Home treatments fail to relieve symptoms, and the itching becomes unbearable.

Health care professionals can provide stronger medications or suggest alternative treatments to help manage symptoms.

Mite bites can be a surprising annoyance during cicada emergence seasons, but understanding why they occur and how to protect yourself can help you avoid these pesky bites. By following simple preventive measures and using effective treatments, you can reduce discomfort and enjoy the outdoors with greater peace of mind. If bites persist or cause severe symptoms, don't hesitate to consult a health care provider for advice.
