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?
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.
What do I do with a dead blue jay or crow?
Please call the office (989-755-5751) to report corvid birds (blue jays and crows) that have died in the last 24 hours.
Do not handle the bird, we will send a technician to collect the bird for testing.
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 Australian elephant mosquito Toxorhynchites speciosus (1.5").
Some species have very similar markings while some look very different like the Sabethes.
Males are identified by their fuzzy antennas.
