As summer heats up in Washington, DC, so does the activity of mosquitoes and ticks. Recent environmental conditions—mild winters, wet springs, and hot summers—are fueling a surge in both pests. This increase raises the risk of diseases like Lyme, ehrlichiosis, alpha-gal syndrome, and more, making it essential for residents to stay informed and take preventive measures.
The rising temperatures and humidity levels not only create a hospitable environment for ticks and mosquitoes but also support their breeding cycles. As warmer weather becomes more common due to climate change, these pests thrive, leading to a greater risk of infection for those who spend time outdoors.
Ticks to Watch: Deer (Blacklegged) & Lone Star
Among the most concerning pests in the area are the deer ticks, also known as blacklegged ticks. These ticks are notorious carriers of Lyme disease, which the CDC estimates affects around 476,000 people annually in the U.S. This figure highlights the need for vigilance, especially in areas where these ticks are prevalent.
In addition to deer ticks, the Lone Star tick is becoming a notable concern in Washington, DC. Once largely confined to the Southeast, these ticks are making their way northward, bringing their capabilities to transmit diseases like ehrlichiosis and potentially causing alpha-gal syndrome, a red-meat allergy. Reports indicate a dramatic rise in cases associated with Lone Star ticks, possibly affecting nearly half a million Americans.
As the summer progresses, emergency room visits for tick bites are at their highest since 2019, with tick populations up by 30–40% year-over-year. Awareness of tick activity is crucial for anyone planning outdoor activities.
Mosquito Watch
Similar to ticks, mosquito activity is also peaking and will continue to do so until the first hard frost, typically occurring between mid-October and mid-November in DC. Climate change plays a significant role in this as well; with the increased temperatures, mosquitoes are capable of undergoing multiple breeding cycles during a single season.
These buzzing pests are not only bothersome but also carry serious diseases like the West Nile virus, which can lead to severe neurological illnesses. Keeping track of mosquito populations and understanding how to manage them can help mitigate the risk of exposure to these dangerous diseases.
Protect Yourself & Loved Ones
Tick Safety
Preventing tick bites is your best defense against the diseases they carry. Here are a few essential tips:
Avoid wooded or high-grass zones: Ticks thrive in these environments, so be cautious when wandering off the beaten path.
Apply repellents: Use products containing DEET, picaridin, or IR3535 with a concentration of 20% or higher on exposed skin.
Treat your clothing: Applying 0.5% permethrin to your clothes and gear can create an additional layer of protection.
Conduct thorough tick checks: After spending time outdoors, check your body for ticks, paying special attention to areas behind the knees, ears, and hairline.
Remove ticks properly: If you find a tick, use fine-tipped tweezers to grab the tick as close to the skin's surface as possible. Pull upward with steady pressure—avoid twisting the tick as it may leave parts behind.
Mosquito Measures
To protect against mosquitoes, here are some key strategies:
Eliminate standing water: Mosquitoes need water to breed, so inspect your property regularly for any stagnant water and eliminate it.
Use EPA-approved repellents: Apply repellents that contain DEET, Picaridin, or oil of lemon eucalyptus when outdoors.
Dress appropriately: Wearing loose, long-sleeved shirts and pants can reduce the likelihood of bites.
Consider screens: Install window and door screens to keep mosquitoes outside, and consider using bug lighting to minimize their attraction to your home.
Pet Protection
Don't forget about your furry friends! Here are some tips for keeping pets safe from ticks and mosquitoes:
Use veterinarian-recommended preventatives: Ensure that your pets are on an effective flea and tick preventive medication.
Check pets after outdoor activities: Pets can carry ticks and introduce them into your home, so inspect them thoroughly after they've been outside.
Know the Signs & When to Act
Understanding the symptoms of tick-borne diseases is crucial for early intervention. Lyme disease often starts with a distinctive bullseye rash, which may appear days or weeks after a tick bite. Other symptoms can include fever, headache, fatigue, and joint pain.
Ehrlichiosis, transmitted by Lone Star ticks, can present with flu-like symptoms, including fever, headaches, and muscle aches. In more severe cases, it can lead to complications like respiratory failure or kidney damage.
If you suspect you have been bitten by a tick and experience any of these symptoms, seek medical attention promptly to discuss testing and treatment options.
Conclusion
As the summer unfolds in Washington, DC, it is important to stay vigilant regarding ticks and mosquitoes. With the favorable conditions for these pests, being proactive can significantly reduce the risk of associated diseases.
By practicing prevention strategies, remaining informed about the types of ticks and mosquitoes in your area, and recognizing the symptoms of tick-borne diseases, you can help keep yourself, your loved ones, and your pets safe during this active season.
Let’s make this summer enjoyable and free from the worry of pests—enjoy the great outdoors while keeping health and safety in mind!
