For residents of the Fox Valley—from the bustling streets of Appleton and Oshkosh to the quiet neighborhoods of Neenah and Kaukauna—outdoor living is a way of life. Whether it’s a backyard BBQ, a stroll along the Fox River, or watching the kids play in the yard, our summers are precious.
However, in recent years, the “nuisance” of mosquitoes and ticks has evolved into a significant public health concern. With Wisconsin seeing record-breaking numbers of tick-borne illnesses and shifting mosquito patterns in 2025 and 2026, protecting your property is no longer just about comfort—it’s about safety.
At Fox Valley Mosquito and Tick, we’ve analyzed the latest local data to help you understand the risks and, more importantly, how to mitigate them.
The Silent Threat: Ticks in the Fox Valley
Wisconsin has long been a “hot zone” for tick activity, but 2024 marked a turning point. According to the Wisconsin Department of Health Services, the state recorded over 6,400 cases of Lyme disease in 2024—the highest number on record. As we move through 2026, these trends show no signs of slowing down.
The Common Culprits
In the Fox Cities, you are likely to encounter three main species:
- The Blacklegged (Deer) Tick: The primary carrier of Lyme disease. These ticks are tiny (often the size of a poppy seed) and thrive in the shaded, leafy perimeters of our yards.
- The American Dog (Wood) Tick: Larger and easier to spot, but still capable of transmitting Rocky Mountain Spotted Fever.
- The Lone Star Tick: A newer arrival to Northeastern Wisconsin, this tick is moving north due to warmer winters and can cause Alpha-gal syndrome—a serious allergy to red meat.
Beyond Lyme: Emerging Tick-Borne Illnesses
While Lyme disease gets the most headlines, other illnesses are quietly on the rise in our region:
- Anaplasmosis: Now the second most common tick-borne illness in Wisconsin. In 2024, cases spiked significantly, with many requiring hospitalization. Unlike Lyme, it rarely produces a “bullseye” rash, making it harder to diagnose early.
- Powassan Virus: A rare but severe “neuroinvasive” virus. While cases are fewer, the impact can be permanent neurological damage. It can be transmitted in as little as 15 minutes after a tick attaches.
More Than a Itch: The Danger of Fox Valley Mosquitoes
We often joke that the mosquito is the “State Bird of Wisconsin,” but the reality is increasingly dangerous. The Culex mosquito (the Northern House Mosquito) is found in every county in Wisconsin and is the primary vector for several serious viruses.
West Nile Virus (WNV) Trends
2025 saw a notable 42% increase in West Nile Virus cases across the region. Most people who contract WNV show no symptoms, but for about 1 in 150 people, the virus enters the central nervous system, leading to encephalitis or meningitis.
Jamestown Canyon Virus (JCV)
Wisconsin is consistently one of the top states for Jamestown Canyon Virus. This virus is spread by several different mosquito species that are active in the early spring—often before homeowners even think about starting their pest control treatments.
Why 2026 is Different: Climate and Habitat Changes
You might be wondering: Why does it seem like the bugs are getting worse? There are three main factors driving the surge in the Fox Valley:
- Warmer, Wetter Winters: Ticks are active whenever the temperature is above freezing (32°F). Shorter winters in the Fox Cities mean ticks have a longer window to feed and reproduce.
- The “Floodwater” Effect: Heavy spring rains in the Valley create temporary pools of stagnant water. This leads to “synchronized hatching,” where billions of mosquito eggs hatch simultaneously, overwhelmed unprepared homeowners.
- Expanding Deer Populations: As our local deer populations thrive, they bring ticks directly into residential backyards in places like Sherwood, Greenville, and Combined Locks.
How to Protect Your Family and Pets
The goal of pest management isn’t just to kill bugs—it’s to break the life cycle. Here is how you can “Fight the Bite” in your own backyard:
1. The “Tipping” Rule
Mosquitoes only need a bottle cap full of water to breed. After every Fox Valley rainstorm, walk your property and tip over anything holding water:
- Clogged gutters
- Children’s toys and sandboxes
- Tarps over woodpiles or boats
- Birdbaths and pet water bowls
2. Create a “Tick-Safe” Zone
Ticks hate the sun. You can reduce their presence by:
- Mowing your lawn frequently to keep grass short.
- Creating a 3-foot wide barrier of wood chips or gravel between your lawn and any wooded areas.
- Removing leaf litter and tall weeds from the edges of your property.
3. Professional Barrier Treatments
While DIY sprays provide temporary relief, they rarely address the source of the problem. Fox Valley Mosquito and Tick uses a specialized barrier treatment designed for the unique climate of Wisconsin.
- Targeted Protection: We don’t just spray the grass; we target the underside of leaves and the dense foliage where mosquitoes rest during the heat of the day.
- Tick Perimeter Sprays: We create a shield around your home’s “transition zones” (where the woods meet the yard) to stop ticks from migrating toward your patio.
- Safety First: Our products are pet and child-safe once dry, allowing your family to return to the yard within 30 minutes of application.
The Importance of Early Intervention
One of the biggest mistakes Fox Valley homeowners make is waiting until they see a swarm to call for help. By the time you are being bitten, there are already thousands of larvae developing in your neighborhood.
Starting your mosquito and tick program in late April or early May allows us to catch the first generation of pests. This “early hit” prevents the exponential population growth that usually ruins outdoor plans in July and August.
Final Thoughts: Your Backyard Should Be a Sanctuary
You shouldn’t have to choose between fresh air and the fear of a tick bite. By understanding the real risks of Lyme disease, Anaplasmosis, and West Nile Virus, you can take the necessary steps to protect your loved ones.
