Fogging Update: Surveillance Leads to Adult Mosquito Control

Mosquito surveillance conducted this week in Mohave Valley by the Mohave County Department of Public Health, Environmental Health Division (MCDPH-EHD) revealed the following locations that meet the protocol to conduct mosquito fogging. The MCDPH-EHD uses the CDC’s recommended matrix as a guide of when to fog.

FOGGING: Adult mosquito control application will take place the evening of Monday, July
28th, 2025, after 8:00 p.m., weather permitting. Baron Pest Solutions was awarded the contract to provide fogging services within Mohave County and will be conducting the ground fogging application.

Areas to be fogged include:

• Willow Drive and south to Laguna Road, east and west between Mohave Valley Hwy 95 and Mountain View Road.
  • Willow Drive and north to King Street, east and west from Boundary Peak Road to Aquarius Drive.
  • Jerome south to Hulet Dr., between Calle Del Media and Aquarius Drive, and including Dutchman Drive and Lost Acres Drive.

The adulticide being used is MasterLine Kontrol 4-4. According to the National Pesticide Information Center, this is an insecticide registered for use against mosquitoes made from pyrethrins. Pyrethrins are insecticides that are derived from the extract of chrysanthemum flowers. Types of products that contain pyrethrins minclude indoor bug bombs, human head lice treatments, and pet flea sprays.

PRECAUTIONS: The Environmental Protection Agency recommends the following steps to
help reduce possible exposure to insecticides during spraying:

• Whenever possible, remain indoors with windows closed.
• You might consider turning off your air conditioning when spraying is taking place.
• If you are outdoors, avoid eye contact with the spray. If you get pesticide spray in your eyes, immediately rinse them with water or eye drops.
• Your child’s health should not be affected by the low levels of pesticides used in mosquito control. However, bring laundry and toys indoors before spraying begins and wash with soap and water if
  exposed to pesticides during spraying
• Bring your pets indoors and cover ornamental fishponds to avoid direct exposure.
• Cover swimming pool surfaces when it is feasible. Special precautions or waiting periods are not usually necessary for outdoor swimming pools given the small concentrations of
  pesticides used.
• Wash exposed skin surfaces with soap and water if you come in contact with pesticide.
• Wash exposed fruits and vegetables, such as homegrown or purchased from an outside vendor, with water before storing, cooking, or eating them.
• There is no need to relocate during spraying, but consult a physician if you have physical or psychological concerns regarding the spraying.
• If you think pesticides are making you sick, seek medical attention as necessary.
