Pleasant Hill’s annual mosquito spraying begins in June. Depending upon weather conditions, the city truck sprays every Tuesday and Thursday evenings between 7 to 10:30 p.m.
The product we use is Anvil 2 + 2. This is a “contact” insecticide; which means only those mosquitoes that come in direct contact with the mist will be killed. There is no residual control associated with this product since it dissipates from the environment within hours of 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 in June. We generally spray Tuesday and Thursday evenings from 7 to 10:30 p.m. 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.
Anvil 2 +2 is applied at very low concentrations; most people would not be expected to experience any adverse effects from exposure to the spray. Nevertheless, Anvil 2 +2 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.
Mosquitoes carry diseases such as Encephalitis and West Nile Virus. They should be taken seriously.
