Mosquitoes are associated with the summer but can thrive during the fall season, remaining active until the temperature drops below 60 degrees. In the United States, mosquitoes are known to spread West Nile virus, eastern equine encephalitis and, in recent months, chikungunya virus. These illnesses do not have specific vaccines or treatments, so prevention of mosquito bites throughout the summer and fall months is crucial. Even with proper treatment, it is recommended that everyone apply bug spray when spending time outdoors. This will significantly decrease the likelihood of being bitten by an infected mosquito.

Mosquito-borne diseases have claimed more lives than all the World Wars combined! St. Louis, Missouri area residents are right to be concerned with mosquitos – they carry some of the world’s deadliest diseases, including:

  • Malaria
  • Dengue
  • West Nile virus
  • Chikungunya
  • Yellow fever
  • Filariasis
  • Tularemia
  • Dirofilariasis
  • Japanese encephalitis
  • Saint Louis encephalitis
  • Western equine encephalitis
  • Eastern equine encephalitis
  • Venezuelan equine encephalitis
  • Ross River fever …and more


This deadly disease is a parasitic infection that is spread from the bite of a carrier mosquito. Once an infected mosquito bites a human, the parasites multiply in the host’s liver before infecting and destroying red blood cells. Symptoms include: fever and chills; impaired consciousness; prostration or adopting a prone position; multiple convulsions; deep breathing and respiratory distress; abnormal bleeding and signs of anemia; clinical jaundice; and vital organ dysfunction.

Yellow Fever:

This disease can be transferred to humans through the bite of an infected mosquito. Symptoms can take 3-6 days to develop and may include fever, chills, headache, backache, and muscle aches. About 15% of people who get yellow fever develop serious illness that can lead to bleeding, shock, organ failure, and in the worst cases, death.

West Nile Virus (WNV):

Of course, the Nile is a long way from the St. Louis, Missouri area metroplex, but West Nile encephalitis (or meningitis) travels here with the mosquitos each summer. A mosquito-transmitted virus causes most cases of West Nile infection. This disease can lead to coma, tremors, convulsions, paralysis, and even death. The disease is initially difficult to detect, because most people infected with West Nile virus either don’t develop symptoms or have only a minor fever and headache. Some cases, however, can develop into life-threatening conditions such as inflammation of the spinal cord or brain.

Zika Virus:

Most people who contract the Zika virus show no symptoms of the infection. When symptoms occur, they typically begin with a mild headache and fever. Within a day or two, a maculopapular rash may appear and can cover many parts of the body. Following the rash, people generally report continued fever, malaise, and body aches. Other symptoms may include diarrhea, constipation, abdominal pain, and dizziness.

Eastern Equine Encephalitis (EEE):

Symptoms usually occur 4-10 days after a bite from an infected mosquito and include fever, headache, vomiting, muscle aches, joint pain, and fatigue. In rare cases, infection occurs in the brain and spinal cord. This leads to sudden high fever, stiff neck, disorientation, seizures, and coma. There is no human vaccine for EEE.

Reduce Your Risk Of A Mosquito Bite Using Preventative Measures!

How To Treat For Mosquitos On Your Property

Inspect Area: Look for any place that allows water to collect and lay stagnant, thereby creating ideal conditions for mosquitos. They lay their eggs in stagnant water, so eliminating these areas can dramatically decrease the number of mosquitos you have on your property.

Apply Larvicide Treatment (as appropriate):

Properly spray stagnant water and/or areas subject to periodic flooding that will allow immature mosquitoes to develop. Treating these areas will help prevent the proliferation of mosquitoes.

Apply Barrier Treatment:

Once you treat those areas that provide mosquitoes the shelter they seek, you can add a secondary layer of protection for live mosquitoes. Apply this treatment to bushes, plants, foliage, and structures where mosquitos shelter and rest.

Repeat As Needed: Eliminating mosquitoes from your yard may require multiple treatments. Just as important…remain vigilant in your efforts to eliminate areas of stagnant water on your property. This will keep the mosquitoes to a minimum.
