The Problem

Mosquitoes are the deadliest animals on Earth, responsible for over 700,000 deaths annually worldwide due to diseases like malaria, dengue, and Zika. In the United States, West Nile virus is the leading mosquito-borne illness, and Tennessee consistently reports cases each year. The Tennessee Department of Health confirmed over 20 human cases of West Nile in 2023 alone, with many more unreported. Beyond disease, mosquitoes ruin outdoor activities and can cause severe allergic reactions in some people. Their lifecycle is fast: in warm, stagnant water, an egg can develop into a biting adult in just 7-10 days. That means a single neglected birdbath can produce hundreds of mosquitoes every week.

Warning Signs

  • Frequent mosquito bites, especially during dawn and dusk
  • Seeing mosquitoes resting on walls, under leaves, or in shaded areas
  • Larvae (wrigglers) swimming in standing water like gutters, flower pots, or ponds
  • High-pitched buzzing near ears at night
  • Swarming behavior, particularly near breeding sites
  • Pet scratching more than usual (mosquitoes bite animals too)

Risks of Waiting

  • Increased risk of West Nile virus and other mosquito-borne diseases
  • Unusable outdoor spaces during prime summer months
  • Rapid population growth—a few mosquitoes can become thousands in weeks
  • Negative impact on property value and enjoyment for potential buyers
  • Potential for severe allergic reactions or secondary infections from scratching bites

Treatment Options

Barrier Spray Treatment

$70-$150

A licensed technician applies a residual insecticide to foliage and shaded areas where mosquitoes rest. The treatment creates a barrier that kills mosquitoes on contact and continues working for 3-4 weeks.

30-45 minutes per acreBest: Homeowners with moderate to heavy mosquito pressure; provides immediate relief

Larvicide Treatment

$50-$100

Bacillus thuringiensis israelensis (Bti) or methoprene is applied to standing water sources like ponds, rain barrels, and drainage ditches. These products kill mosquito larvae before they become adults.

15-30 minutes per siteBest: Properties with persistent water features; long-term prevention

Misting System Installation

$1,500-$3,000

An automated system of nozzles connected to a timer dispenses insecticide at preset times (usually dawn and dusk). The system covers the entire yard.

Installation takes 2-4 hoursBest: High-end residential or commercial properties; hands-off continuous control

Seasonal Mosquito Control Plan

$400-$1,200

A package of 5-8 barrier spray treatments spaced 3-4 weeks apart covering the entire mosquito season from April to October. Includes re-treatment subject to written provider terms between scheduled visits if needed.

Full season coverageBest: Homeowners wanting worry-free, season-long protection

The Mosquito Lifecycle: Why Timing Matters for Control

Understanding the mosquito lifecycle is key to effective control. Mosquitoes go through four stages: egg, larva, pupa, and adult. Eggs are laid on or near water and can survive dry conditions for months. Once submerged, they hatch into larvae (wrigglers) that feed on organic matter. Larvae molt several times before becoming pupae, and within 2-3 days, adult mosquitoes emerge. The entire process can take as little as 7-10 days in warm weather. This rapid reproduction means that a single female mosquito can produce up to 300 eggs at a time. In Tennessee, where temperatures are warm from April through October, mosquitoes can complete multiple generations in one season. That's why larvicide treatments are so effective: breaking the lifecycle before adults emerge prevents new biting mosquitoes. Professional services often combine larviciding with adulticide barrier sprays for comprehensive control.

Mosquito-Borne Diseases in Tennessee: What You Need to Know

While Tennessee doesn't have the same risk as tropical regions, mosquito-borne diseases are a real concern. West Nile virus (WNV) is the most common, transmitted by Culex mosquitoes. The Tennessee Department of Health reports cases every year, with 23 human cases in 2023. Symptoms include fever, headache, body aches, and sometimes neurological issues. La Crosse encephalitis is another virus found in the Appalachian region, transmitted by Aedes triseriatus. It primarily affects children. Eastern equine encephalitis (EEE) is rare but has a high mortality rate. Additionally, heartworm is a serious risk for dogs—a single mosquito bite can transmit the parasite. Prevention is the best defense. Using repellents, eliminating standing water, and scheduling professional treatments reduce your family's and pets' exposure.

Tennessee's Regional Mosquito Variations: East vs. Middle vs. West

Tennessee's geography creates distinct mosquito challenges. West Tennessee, including Memphis and the Mississippi Delta, has high humidity, frequent flooding, and many drainage ditches. The Asian tiger mosquito (Aedes albopictus) is prevalent here—an aggressive daytime biter that breeds in small containers. Middle Tennessee, around Nashville, has a mix of suburban and rural areas with many ponds and creeks. Culex mosquitoes (West Nile vectors) are common. East Tennessee, including Knoxville and the Great Smoky Mountains, has cooler temperatures but dense forests and abundant rainfall. Here, Aedes triseriatus (tree-hole mosquito) breeds in rot cavities and is a vector for La Crosse encephalitis. Professional control should be tailored to these regional differences. For example, barrier sprays in West Tennessee should target shaded areas under dense vegetation, while in East Tennessee, larviciding tree holes is crucial.

When to Call a Professional

Call a professional when you've noticed a persistent mosquito problem despite your own efforts, when you have standing water sources you can't eliminate (like a pond or drainage ditch), or if you or family members have had severe reactions to bites. Also consider professional help if you're planning an outdoor event and need results that vary by property and provider. The Tennessee mosquito season is long—from April to October—and DIY methods often fail to keep populations down for the whole season.

DIY vs Professional

DIY mosquito control can help reduce numbers but rarely eliminates them. Removing standing water, using EPA-approved repellents (like DEET or picaridin), and running fans on patios are effective low-cost strategies. However, adult mosquitoes can travel up to a mile from breeding sites, meaning your neighbors' problems can become yours. Professional treatments use longer-lasting, more effective insecticides applied by trained technicians who know where mosquitoes hide. For most Tennessee homeowners, especially those with kids and pets, a professional service provides peace of mind and consistent results. The cost—around $70-$150 per treatment—is often worth the time and frustration saved.

Local Context

Tennessee's climate is classified as humid subtropical, with hot summers and mild winters. The mosquito season typically runs from April through October, but in the southernmost counties like Shelby (Memphis), mosquitoes can be active year-round during warm spells. The Tennessee Valley Authority's reservoirs and the Mississippi River create vast breeding grounds in the west. In Middle Tennessee, the Cumberland Plateau and numerous limestone springs provide habitat. East Tennessee's higher elevations have a slightly shorter season but more forest-dwelling species. Urban centers like Nashville, Memphis, Knoxville, and Chattanooga all experience high mosquito pressure, but the species mix varies. For example, Memphis struggles with floodwater mosquitoes after heavy rains, while Knoxville sees more tree-hole mosquitoes. Professional services that understand these nuances provide more effective treatments. Mosquito Control's technicians are trained to identify local species and apply targeted solutions.

Prevention Tips

  • Eliminate standing water weekly: check gutters, flower pot saucers, birdbaths, children's toys, and trash can lids.
  • Keep grass cut and shrubs trimmed—adult mosquitoes rest in tall grass and shaded vegetation.
  • Install or repair window and door screens to keep mosquitoes out of your home.
  • Use EPA-approved mosquito repellents containing DEET, picaridin, or oil of lemon eucalyptus when outdoors.
  • Run a fan on your patio—mosquitoes are weak fliers and a steady breeze keeps them away.
  • Treat rain barrels with Bti dunks to kill larvae without harming plants or pets.
  • Encourage natural predators like bats, dragonflies, and purple martins by installing bat houses or birdhouses.

💡 Did You Know?

  • Only female mosquitoes bite—they need the protein in blood to develop their eggs. Males feed on nectar.
  • Mosquitoes can detect carbon dioxide from your breath from up to 50 feet away, acting as a homing signal.
  • Some mosquitoes, like the salt marsh species, can fly up to 40 miles from their breeding site.

Frequently Asked Questions

What is the best way to get rid of mosquitoes in my yard?
The most effective approach combines eliminating standing water, keeping vegetation trimmed, and applying a EPA-approved barrier spray. For long-term control, professional treatments every 3-4 weeks during mosquito season are recommended. Mosquito Control uses products that target both adult mosquitoes and larvae.
How long does a mosquito treatment last?
Most professional barrier sprays remain effective for 3-4 weeks, depending on rainfall and temperature. Heavy rain can wash away the product, but many companies offer re-treatment subject to written provider terms if this happens within a certain window. Mosquito Control guarantees their treatments for 21 days.
Are mosquito treatments safe for my pets and children?
Yes, when applied by independent pest-control providers using EPA-registered products. Technicians take care to avoid spraying directly on pets, children, or their play areas. The products used break down quickly in the environment and are applied at low concentrations. Always keep pets indoors during treatment and until the spray dries (about 30-60 minutes).
When is mosquito season in Tennessee?
Mosquito season in Tennessee typically runs from April through October, with peak activity in July and August. In the southern part of the state, like Memphis, mosquitoes can be active year-round during warm spells. The first hard frost usually ends the season, but that can vary from late October to early November.
What diseases do mosquitoes carry in Tennessee?
The primary mosquito-borne disease in Tennessee is West Nile virus. Less common but present are La Crosse encephalitis (especially in eastern Tennessee) and Eastern equine encephalitis. Heartworm is also a significant risk for dogs. The CDC recommends using EPA-registered repellents to reduce the risk of infection.
How much does professional mosquito control cost in Tennessee?
Per-treatment costs range from $70 to $150, depending on property size and infestation level. Seasonal plans covering the entire mosquito season (usually 5-8 treatments) range from $400 to $1,200. Mosquito Control offers inspection terms that vary by provider and a service guarantee—call +1 888 546 7983 for a quote.
Can mosquitoes breed in my gutters?
Yes! Clogged gutters that hold standing water are a common breeding site. Even a small amount of water with organic debris can support hundreds of mosquito larvae. Clean your gutters at least twice a year and ensure they drain properly.
What is the difference between a misting system and barrier spray?
A misting system is an automated network of nozzles installed around your property that dispenses insecticide at preset times (usually dawn and dusk). It provides continuous, hands-off control but requires a higher upfront investment ($1,500-$3,000). Barrier spray is a one-time treatment applied by a technician that lasts 3-4 weeks. Misting systems are best for large properties or commercial settings, while barrier sprays are more cost-effective for most homeowners.
