While the aerial spraying of mosquitoes to combat Eastern Equine Encephalitis is wrapping up in Southwest Michigan, help from Mother Nature may not arrive for some time.
Officials at the Michigan Department of Health and Human Services are hoping the first hard freeze will help ease the threat of EEE.
The extended forecast for the weekend is calling for cooler temperatures but overnight lows will only dip into the mid to upper 30s.
The web site www.accuweather.com is calling for low temperatures in the 30s in the days before Halloween and National Weather Service forecasters are calling for a warmer-than-normal fall in western Michigan.
A hard freeze usually happens in south central Michigan between October 15th and 20th. It takes place when the mercury drops to less to 28 degrees for more than four hours.
According to MDHHS, as of Saturday, more than 430,000 acres had been sprayed. The areas sprayed on Sunday night included parts of Calhoun County.
The Sunday treatment included the Fort Custer Training Center which crosses into Kalamazoo County after the Center approved the spraying. Kalamazoo County spraying was called off because of the number of residents who opted out.
