Mosquito Control in Nashville, TN

Nashville’s Metro Public Health Department actively traps and tests mosquitoes for West Nile virus across Davidson County every week. What it doesn’t do is spray to kill adult mosquitoes. That gap between testing and actual treatment is where most of the pressure on your own yard gets decided.

Teddy’s Pest Solutions provides monthly, eco-friendly mosquito control throughout Nashville, addressing both everyday backyard breeding sites and the wooded, water-adjacent conditions that shape mosquito activity across Davidson County. Our mosquito control services are built around your property’s actual conditions, not a generic, one-size-fits-all treatment plan.

Why Nashville’s Wooded Waterways Sustain Mosquito Activity

The Cumberland River, the creeks that feed it, and green spaces like Shelby Bottoms, Radnor Lake, and Centennial Park give Nashville a lot of shaded, wooded habitat close to residential neighborhoods. Combined with a humid subtropical climate and hot, wet summers, that mix of woods and water keeps mosquito activity high from roughly May through October.

What sets Nashville apart is how the city actually responds. Metro Public Health’s Pest Management team traps mosquitoes at around 40 sites across Davidson County and applies larvicide where larvae turn up, but it does not spray to kill adult mosquitoes. When a trap tests positive for West Nile virus, the response is educational fliers to nearby homes, not a fogging truck. That means the adult mosquitoes already flying around your yard are yours to deal with, not the city’s.

Facts About Mosquitoes Relevant to Nashville

Several mosquito behaviors and local details are particularly relevant to residents throughout the Nashville and Davidson County area:

• Metro Public Health tests for West Nile virus but does not spray for adult mosquitoes, relying instead on larvicide and public education when a trap comes back positive.
• West Nile virus activity rose sharply in recent years. Nearly 23 percent of Davidson County traps tested positive in 2023, up from roughly 2 percent in each of the two prior years, and 2023 also brought Nashville’s first confirmed human case in more than five years.
• La Crosse encephalitis, spread by the eastern treehole mosquito, disproportionately affects children age 16 and younger, and Tennessee sits within the region where the disease is most consistently documented.
• The eastern treehole mosquito breeds specifically in tree holes and other containers, not ground pools, which makes Nashville’s tree-heavy neighborhoods and parks particularly relevant habitat.
• Female eastern treehole mosquitoes can pass La Crosse virus directly to their eggs, so infected offspring can carry the virus through every stage of development without ever biting an infected host themselves.
• Aedes albopictus, also common in Nashville, has been documented carrying La Crosse virus in addition to its more familiar role spreading Zika, dengue, and chikungunya elsewhere.

For more on how La Crosse virus spreads and who’s most at risk, the University of Tennessee Institute of Agriculture has published a fact sheet on La Crosse virus neuroinvasive disease.

Why Mosquito Control Matters for Nashville Properties

Ignoring mosquito activity in a city where the public health response stops at testing tends to leave properties more exposed than homeowners expect.

• The city’s program doesn’t reduce adult mosquito populations. Because Metro Public Health only applies larvicide and doesn’t fog for adults, the mosquitoes already flying around your property need a separate solution.
• Wooded, tree-heavy properties carry added risk. Tree holes near creeks, greenways, and mature landscaping are exactly the habitat the eastern treehole mosquito prefers.
• La Crosse encephalitis is a genuine concern for families with kids. Unlike West Nile virus, which affects people of all ages, La Crosse disproportionately affects children.
• West Nile virus risk has been trending upward, with 2023’s positive trap rate far higher than the two years before it.
• Pets face exposure risk as well. Mosquitoes can transmit heartworm to dogs, making yard-level control relevant for pet owners throughout the Nashville area.
• Property value and outdoor usability are both affected. Heavy mosquito pressure can make patios, yards, and wooded properties far less enjoyable during Nashville’s warm-season months.

Signs You May Have a Mosquito Problem

• Daytime biting activity near trees, wooded areas, or shaded parts of the yard
• Persistent biting at dusk or after dark, consistent with West Nile-carrying species
• Standing water in tree holes, containers, or low spots near creeks and greenways
• A flier from Metro Public Health noting West Nile virus activity near your home
• Pets scratching at bites or seeming uncomfortable spending time outdoors
• Store-bought sprays or citronella candles that stop working within days

If you’re dealing with any of these signs around your Nashville property, our team can identify breeding sites, including tree holes and creek-adjacent containers the city’s testing program won’t treat, through a full mosquito inspection and treatment consultation.

Our Monthly, Eco-Friendly Mosquito Control Process

Teddy’s Pest Solutions uses an environmentally responsible approach to mosquito control designed to address both everyday backyard breeding sites and the tree hole and waterway-driven patterns specific to Nashville. Because the city’s own program stops at testing and larvicide, we only offer monthly service that actually treats adult mosquito activity. We don’t do one-time or seasonal-only visits.

Step 1: Full Property Inspection. We assess your Nashville property for standing water, breeding sites, and vegetation that provides mosquito harborage, including tree holes, containers, and proximity to creeks or greenways.

Step 2: Eco-Friendly Targeted Treatment. We apply low-toxicity, environmentally conscious products to breeding sites and resting areas, and we install and maintain In2Care mosquito stations around the property. In2Care is a green-certified system that lures egg-laying female mosquitoes into a station, where they pick up a biological larvicide and a naturally occurring fungus, then carry that treatment back out to hidden breeding sites, including tree holes, that a technician could never treat directly. It’s an EPA-registered, eco-friendly option for use around people, pets, and pollinators when maintained as directed. You can read more about how the stations work directly from In2Care’s manufacturer, Envu.

Step 3: Standing Water and Prevention Guidance. We identify ongoing water sources around the property, including tree holes and creek-adjacent risks, and provide clear recommendations for reducing them between visits.

Step 4: Monthly Service Visits. Our team returns every month to refill and check the In2Care stations, retreat resting areas, and reassess new breeding activity across Nashville’s warm-season months. Mosquito populations don’t stay down after a single treatment, so monthly visits are what actually keep control consistent, filling the gap the city’s testing-only program leaves behind.

Why Nashville Property Owners Choose Teddy’s Pest Solutions

• Understanding of tree hole and waterway-driven breeding. We factor in how Nashville’s wooded parks and creek corridors can contribute to mosquito activity when building your treatment plan.
• Awareness of what the city’s program doesn’t cover. Our team treats adult mosquito populations directly, filling the gap left by a public program built around testing rather than treatment.
• A genuine eco-friendly standard. Our mosquito control methods, including the In2Care station system, are selected to be effective while minimizing unnecessary environmental impact.
• Treatment tailored to what we actually find. We adjust station placement and treatment focus based on your property’s inspection findings, not a fixed, generic template.
• Clear reporting after every visit. You’ll always know what was found, what was treated, and what to expect going forward.

The City Tests. We’re the Ones Who Actually Treat Your Yard.

Metro Public Health does important work tracking where West Nile virus shows up, but tracking isn’t treatment, and the mosquitoes biting you at a backyard cookout don’t care that a trap two miles away came back negative. Teddy’s Pest Solutions handles the part the city’s program was never built to do, treating the adult mosquitoes and tree hole breeding sites on your actual property, month after month.

Frequently Asked Questions

Does Nashville Metro Public Health spray for mosquitoes?

Not for adults. The department traps and tests mosquitoes for West Nile virus and applies larvicide where larvae are found, but it does not fog or spray to reduce adult mosquito populations.

Is La Crosse encephalitis a real risk for my kids in Nashville?

It’s a documented regional risk. La Crosse virus, spread by the eastern treehole mosquito, disproportionately affects children 16 and younger, and Tennessee falls within the area where the disease is most consistently reported.

Is West Nile virus getting worse in Nashville?

Recent data suggests activity has increased. Nearly 23 percent of Davidson County traps tested positive for West Nile virus in 2023, compared with roughly 2 percent in each of the two years before, and 2023 also brought the city’s first confirmed human case in more than five years.

What is In2Care, and why do you use it?

In2Care is a mosquito station system that lures egg-laying female mosquitoes inside, coats them with a biological larvicide and fungus, then lets them fly back out and spread that treatment to breeding sites like tree holes that a technician could never treat directly. It’s a green alternative to relying purely on chemical sprays, and it keeps working in between our monthly visits.

Why do tree holes matter for mosquito control?

The eastern treehole mosquito, the main vector for La Crosse virus, breeds specifically in tree holes and similar containers rather than ground pools, which makes Nashville’s wooded neighborhoods and parks especially relevant habitat.

Why do you treat monthly instead of less often?

Because Nashville’s own mosquito program stops at testing and larvicide, returning every month lets us treat new adult mosquito activity as it happens and adjust as conditions change, rather than leaving that gap unaddressed.

Is your mosquito treatment eco-friendly around children and pets?

Yes. We use eco-friendly, low-toxicity products, including the EPA-registered In2Care system, chosen specifically for effective, eco-friendly mosquito control around households once applied and dried according to our technician’s guidance.

How quickly will I notice a difference after treatment begins?

Most Nashville customers notice fewer mosquitoes within the first couple of weeks, with results continuing to improve as the In2Care stations disrupt the breeding cycle over the following months.
