A mosquito draws blood.

FLORENCE -- Pinal County plans to fog several areas as part of an effort to control mosquitoes during an exceptionally wet monsoon season.

The Pinal County Public Health Services District Environmental Health Division will conduct the mosquito fogging starting Thursday and running through Saturday from 10 p.m. to 5 a.m. each night.

Each area will be fogged on all three days. The areas to be fogged include:

  • Maricopa - the Maricopa Meadows Subdivision
  • North of the Town of Florence – Oasis @ Magic Ranch Subdivision and the adjacent nearby acreage properties
  • Arizona City – the area encompassing Alsdorf Road to the north, Sunland Gin Road to the east, Phillips Road to the south, and Squatter Road to the west

The pesticide that will be used during fogging is called Anvil 2+2. It is a pre-mixed, ready-to-use product that contains two active ingredients: Sumithrin (2%) and piperonyl butoxide (2%). Sumithrin is a man-made version of a natural pesticide found in chrysanthemum flowers while Piperonyl butoxide helps Sumithrin work more effectively against mosquitoes. Anvil 2+2 is registered with the U.S. EPA and is effective against mosquitoes that carry West Nile Virus.

According to the county there are several things that residents can do to reduce exposure during fogging:

  • Close all windows and doors. Air conditioners can still be operated, but if they have vents to bring in outside air, they should be closed. Weather permitting, turn off evaporative coolers
  • Stay inside your home
  • If possible, bring pets inside

Thirty minutes after the end of the scheduled fogging each night, you may resume normal activities
