Mosquito Fogging at River Valley High School Next Week

Mosquito control (fogging) and suppression (larvicide) treatments will be applied at River Valley High School in Mohave Valley the week of August 12-16, 2024, as coordinated by the Mohave County Department of Public Health, Environmental Health Division (MCDPH-EHD). Baron Pest Solutions was awarded the contract to provide mosquito treatment services within Mohave County and will be conducting the larvicide and adulticide applications.

FOGGING: Adult mosquito control application will take place Monday night, August 12, 2024, after 8:00p.m., weather permitting. Areas to be fogged include:

  • River Valley High School campus and sports fields, including the North and West roadways
    adjacent to the campus
  • LARVICIDING: Larval mosquito application will take place the morning of Friday, August 16,
    2024, beginning at 5:00a.m. and ending approximately 9:00a.m. Areas to receive larvicide
    include:
  • River Valley High School campus and sports fields.
  • 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 include indoor bug bombs, human head lice treatments, and pet flea sprays.

    The larvicide being used is MetaLarv S-PT. This insecticide is a spherical pellet applied to the ground and withstands multiple waterings. The active ingredient is (S)-methoprene, an insect growth regulator which prohibits the development of mosquitos beyond the larval stage. Types of products that contain methoprene include flea treatments for dogs and cats, insect baits and sprays, and over 500 pesticide products.

    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.
    • Consider turning off air conditioning when spraying is taking place.
    • If outdoors, avoid eye contact with the spray. If any pesticide spray gets in eyes, immediately rinse with water or eye drops.
    • A 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 pets indoors and cover ornamental fishponds to avoid direct exposure.
    • Cover swimming pool surfaces when 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 there is any 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 there is any physical or psychological concerns regarding the spraying.
  • If it’s believed pesticides are making anyone sick, seek medical attention as necessary.
  • Individuals with questions about pesticides should call the National Pesticide Information Center at 1-800-858-7378 from 6:30am-4:30pm PST. The NPIC is staffed by trained pesticide specialists who have toxicology and environmental chemistry education and training needed to provide answers to pesticide questions.
