Frequently Asked Questions


What is the millage for?

This millage will fund mosquito control operations and a new facility to provide public health community mosquito control for all Saginaw County communities for the next 20 years. This level of funding is needed to address rising costs associated with services, products, energy, vehicles, equipment, employees, etc. as well as a needed facility.

In addition to addressing inflationary costs, this funding will allow us to better respond to future challenges posed by mosquitoes, diseases, nature, and regulation. We are a tax funded agency that performs a variety of preventative and responsive mosquito control services throughout all of Saginaw County.

How long is the millage for?

The millage will be for a 20-year period beginning in 2022 and ending in 2041.
Mosquito control has been funded through a millage for over 45 years. To learn more click: MILLAGE

How much will the millage cost?

The proposed rate will be up to 1.0 mill ( or $1.00 per $1,000 of taxable valuation), calculated according to previous rate increases. This will allow us to continue providing similar services with the anticipation of improved technology or regulatory changes.

Example: A home with a market value of around $100,000 with an assessed value of $50,000 would provide the following annual contribution for mosquito control at the rate of 1.0 mills:

Assessed value $ / $1000 x millage rate or 50,000/1000 x 1.0 = $50.00/year*

*This equates to $4.16 per month and is $1.50/month more than the current 0.64 mosquito millage.

Is SCMAC moving? Why should I fund a new building?

Our current facility provides us the means to test and calibrate our equipment, however, due to community improvements around our current location and their impact on our operations and accessibility, SCMAC will need to relocate. A new facility will allow our focus to remain on our services and their accessibility to residents.

Therefore, the majority of the proposed millage funding will still go to operations and services, while a smaller portion is needed to fund the new facility. The new facility will be substantially funded by the proposed property transaction of our location. The Saginaw City School District is purchasing our property for $4 million and also providing a property of about 30 acres. The purchase agreement has been agreed in principle but still needs to be ratified with the School District. This facility will promote the next generation of responsible, effective, and accessible mosquito control.

Does a YES vote support or oppose this proposal?

A YES vote supports the proposal and a NO vote opposes it.

When is the election?

The election will be held on Tuesday, November 8, 2022.

Who can vote in this election?

Registered voters of Saginaw County who will be 18 years of age or older can vote in this election.

Do I need to update my voter registration?

Registered voters need to update their voter registration if they have changed their name or address since the last time they voted. You can do this at any Secretary of State Office or at a local Clerk’s Office.

How will the November 8th ballot be worded?

The wording on the ballot may appear as follows:

For the purpose of funding of Mosquito Abatement Commission operations, for example the control and abatement of mosquitoes and mosquito-borne diseases, mosquito source reduction, public education, and operating expenses, and for the construction of a new mosquito abatement facility, shall the previously voted increase in the limitation on the total amount of general ad valorem taxes which may be imposed for all purposes upon real and personal property in Saginaw, which last resulted in a levy of up to 0.64 mill ($0.64 per $1,000) of taxable valuation, be renewed and increased for a levy of up to 1.00 mill ($1.00 per $1,000) of taxable valuation as finally equalized during the years 2022 – 2041, both inclusive, as authorized by Article 9, Section 6 of the Michigan Constitution of 1963, as amended, which if approved and levied in its entirety, is estimated to raise $5,763,700 in the first year of levy?

How does SCMAC control larval and adult mosquitoes?

Products such as Bacillus thuringiensis subsp. israelensis (Bti) are used to treat water in ponds, storm drains, ditches, etc., where mosquito larvae are found or may develop later. This is called larviciding or larva control.

Ultra Low Volume (ULV) sprays are used to help control adult mosquitoes. This is called adulticiding or adult control.

What do the planes do?

Planes are used at the start of our Spring larva control program to spread Bti on the flooded woodlots across the county. View the aerial map.

How often do the yellow trucks spray?

Truck spraying (adult control/adulticide) frequency, whether weekly, bi-weekly, or monthly depends on mosquito population or mosquito-borne disease. Spraying for adult mosquitoes only controls mosquitoes and disease present at the given time of spray and offers no residual control. Truck spray knocks-down the amount of nuisance or disease activity and may require frequent or occasional treatment. View treatment map

Why are the trucks so loud?

Each spray truck is equipped with units that blows the product out.
This unit is either a mechanical engine or electrical. The mechanical unit produces the loud distinctive sound heard treating ditches during the day or spraying for adult mosquitoes at night. The electrical unit is much quieter and only used for nighttime spraying.

Dead Birds

What do I do with a dead blue jay or crow?

Please call the office (989-755-5751) or use the online form to report corvid birds (blue jays and crows) that have died in the last 24 hours.

What do dead birds have to do with mosquitoes?

Birds carry certain diseases like West Nile virus (WNV). Mosquitoes get the virus from infected birds and then transmit the disease to other birds, animals or people. Blue jays and crows usually die within 24 hours after contracting WNV. Therefore, these corvid birds are a good indicator of WNV activity.

What can homeowners do around their own properties to reduce mosquitoes?

Homeowners can eliminate mosquito breeding sites on their property by periodically emptying water from sources such as buckets, tires, gutters, trash-cans etc. or keeping water clean in swimming pools, dog bowls, bird-baths, etc.

Why are mosquitoes controlled in the larval stage?

The most effective and economical way to control mosquitoes is to prevent them from emerging as biting adults. SCMAC prefers to use products with Bti, a bacteria found in nature.

What is the most effective protection against biting insects?

The most effective treatment is a repellent containing DEET, but there are other repellents available.

Cover your body with light colored clothing (long sleeves, long pants etc.) to make it harder for mosquitoes to bite.


The mosquito undergoes a complete metamorphosis: 1. Egg 2. Larva 3. Pupa 4. Adult

Do all mosquitoes look the same?

Not at all. It is estimated that there are over 3000 species worldwide, about 200 in the USA, about 60 in Michigan and around 30 in Saginaw County.
Most are fairly tiny (1/4") but some species like the Ciliata found in Michigan can be up to an 1". The largest is the elephant mosquito Toxorhynchites (1.5"), also found the the southern United States. The largest tis the Australian Toxorhynchites speciosus.
Some species have very similar markings while some look very different like the Sabethes.
Males are identified by their fuzzy antennas.
