Mosquito Control

Mosquito Spraying

Mosquito Control

Mosquito control manages the population of mosquitoes to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public-health practice throughout the world because mosquitoes spread many diseases, such as malaria, Zika and West Nile viruses. 

Product Used

The product we use is BIOMIST 1.5+7.5 ULV. This is a “contact” insecticide; which means only those mosquitoes that come in direct contact with the mist will be killed. This product also works againts biting and non-biting Midges and Blackflies. There is no residual control associated with this product since it dissipates from the environment within hours of application.

Application

Application is via an Ultra Low Volume (ULV) cold aerosol foggers mounted on a pickup truck. Our driver/applicators are certified and licensed with the State of Iowa Department of Agriculture. 

Depending on seasonal weather conditions, we will typically begin spraying from Memorial Day to Labor Day. This is an as-needed application that takes place in the evening at dusk when weather conditions are favorable and when mosquitoes are most active.

Spraying is halted during times of high winds, heavy rainfall, or temperature extremes that would render the treatment ineffective. During periods of the summer when mosquito populations are low, spraying will usually be reduced or discontinued. 

BIOMIST 1.5+7.5 is applied at very low concentrations; most people would not be expected to experience any adverse effects from exposure to the spray. Nevertheless, BIOMIST 1.5+7.5 is a pesticide. Certain individuals may object to or be particularly sensitive to even the very low levels of material that we apply. 

Tips for personal mosquito control and protection 

  • Do the best you can to eliminate standing water. Buckets, toys, discarded tires, plugged gutters and many other items that hold stagnant water can provide ideal conditions for mosquitoes to reproduce.
  • Use a mosquito repellent containing DEET. 
  • Avoid being outside during the evening hours when mosquitoes are the most active. 
  • Spraying is safe. You do not need to leave an area when truck spraying for mosquito control takes place. If you prefer to stay inside and close windows and doors when spraying takes place you can, but it is not necessary. If you are having any type of health problems after spraying, contact your doctor or healthcare provider. The spray does not harm pets, but you may choose to bring them inside when spraying occurs.
