The primary goal of the program is to protect the public health from diseases transmitted by mosquitoes.  In order to reach this objective, we strive to reduce mosquito populations to tolerable levels, which helps decrease the risk of mosquito-borne disease and nuisance mosquito species to the citizens and visitors of our county. The cornerstone of the mosquito control program is the biology department, whose main function is to determine timing and priority of treatment based on larval and adult mosquito surveys. The biology department also provides an extensive disease surveillance network coordinated through the Michigan Department of Agriculture, Michigan State University, and Michigan Department of Community Health to monitor mosquito-borne diseases. Female mosquitoes are tested for Eastern Equine Encephalitis (EEE), St. Louis Encephalitis (SLE), and West Nile Virus (WNV) and dead American Crows and Blue Jays are tested in-house for WNV infection; confirmation may be performed through MSU's Diagnostic Center for Population and Animal Health. The program controls immature and adult mosquitoes by seeking out and eliminating breeding sites and by using biological controls and insecticides.

In addition to responding to citizen requests, we also initiate mosquito surveillance before the occurrence of summer festivals and community events - attendance at which exceeds one-half million.  Nearly half of these people are Bay County tourists.  

All residents and property owners can assist by eliminating breeding sites, such as stagnant water collecting anywhere on their property.  Bay County Mosquito Control is designed to promote a safe and healthy environment for county residents.

Current News (Updated: 7/30/14)

Mosquito numbers are down in most parts of the county, which is good news.  We still have pockets of higher activity especially near the Saginaw Bay and are working on treating those areas to control adult mosquitoes.  Daytime crews who search for mosquito larvae in aquatic habitats continue to treat larvae so they cannot become adult biters!

We have collected 170 mosquito samples (composed of 4,361 individual female mosquitoes) for virus testing.  They are submitted weekly to Michigan State University's Department of Microbiology and Molecular Genetics lab.  To date, 129 samples have been analyzed; all have been negative.

You may have heard recently about Chikungunya, a viral disease transmitted to people by mosquitoes.  There have been at least 2 cases in Michigan - one from Midland County and one from Wexford County - but both cases were the result of a traveller coming back from the Caribbean where it is locally transmitted by several types of mosquitoes.  Recently, two human cases have occurred in Florida and were acquired from local mosquitoes.

It has occurred in Africa, Southern Europe, Southeast Asia, and islands in the Indian and Pacific Oceans.  In late 2013, Chikungunya was found for the first time on islands in the Caribbean.  Symptoms usually begin 3-7 days after being bitten by an infected mosquito and involve most often fever and severe joint pains, often in the hands and feet.  For more information, visit the Centers for Disease Control website at www.cdc.gov/chikungunya/

TIP:  Remember that summer thunderstorms drop water that collects in containers throughout backyards.  It only takes a few days for a mosquito to find that water and begin laying eggs which will turn into biting adults within a week.  So always keep water dumped from containers or in the case of bird baths, dump and re-fill weekly with fresh water.
