West Nile Virus in Suffolk County: What Homeowners Should Know

Written by EM Pest Control | 7/7/26 3:26 PM

As mosquito season gets underway on Long Island, many Suffolk County homeowners have questions after hearing about West Nile virus in the news. While the discovery of West Nile virus in local mosquito populations is something health officials monitor every year, it's important to remember that awareness—not fear—is the goal. Understanding how West Nile virus spreads, knowing how to reduce mosquito activity around your property, and taking a few simple preventive steps can help you and your family enjoy your outdoor spaces with greater peace of mind this summer.

Has West Nile Virus Been Found in Suffolk County?

Yes. According to the Suffolk County Department of Health Services, West Nile virus was recently found in a mosquito sample collected during the county's routine mosquito surveillance program. This testing is done every mosquito season to monitor mosquito activity, track mosquito-borne diseases, and keep residents informed.

A positive mosquito sample does not mean every mosquito has West Nile virus. It also does not mean homeowners should panic. It simply means mosquito season is active, and it is a good time to take simple steps around your home, such as removing standing water and protecting yourself from mosquito bites.

How Does West Nile Virus Spread?

West Nile virus spreads through the bite of an infected mosquito. Understanding how the virus spreads can help Suffolk County homeowners focus on what really matters and avoid common misconceptions.

It Starts With Birds

Birds are the natural hosts of West Nile virus. When a mosquito feeds on an infected bird, it can pick up the virus. Most birds do not appear sick, which is why health officials monitor mosquito populations throughout mosquito season.

Then Mosquitoes Can Spread the Virus

After becoming infected, a mosquito can spread West Nile virus to people and some animals through its bite. Not every mosquito carries the virus, but reducing mosquito bites and lowering mosquito activity around your property can help reduce your risk.

How It Does Not Spread

The good news is that West Nile virus does not spread through everyday contact. You cannot get it by shaking hands, hugging someone, coughing, or sharing food or drinks. For homeowners, the best way to lower your risk is to reduce mosquito activity and eliminate places where mosquitoes can breed around your property. 

What Are the Symptoms of West Nile Virus?

Many people who are infected with West Nile virus never develop symptoms. In fact, most people don't even realize they've been infected. However, some people may become sick, so it's helpful to know what to watch for.

Most People Don't Feel Sick

According to the Centers for Disease Control and Prevention (CDC), most people who become infected with West Nile virus never develop symptoms. Their immune system fights off the virus without them ever knowing they were infected.

Mild Symptoms Can Occur

Some people may develop mild symptoms a few days after being bitten by an infected mosquito. These can include:

  • Fever
  • Headache
  • Body aches
  • Tiredness
  • Skin rash
  • Swollen lymph nodes

Most people with mild symptoms recover on their own.

Severe Illness Is Less Common

In a small number of cases, West Nile virus can cause more serious illness, especially in adults over 60 and people with weakened immune systems. If you or someone you know develops severe symptoms after a mosquito bite, it's important to contact a healthcare provider promptly.

How Suffolk County Homeowners Can Help Reduce Mosquitoes

You can't eliminate every mosquito in your neighborhood, but you can make your property much less attractive to them. A few simple habits can go a long way during mosquito season.

  • Empty standing water from buckets, flowerpots, toys, tarps, and other containers.
  • Change the water in bird baths regularly.
  • Keep gutters clean so water doesn't collect.
  • Trim overgrown shrubs and mow tall grass where mosquitoes like to rest.
  • Use an EPA-registered insect repellent when spending time outdoors.
  • Repair damaged window and door screens to help keep mosquitoes outside.
