Freeport Mosquito Abatement District (FMAD)

Freeport, IL - The Freeport Mosquito Abatement District reports today a substantial increase of the mosquito population in the district. The district relies on mosquito counts from four locations within the City of Freeport. The levels have quadrupled on Tuesday July 11 since last Thursday July 7. This level is the highest recorded over the last 15 years. As a result a district wide treatment was conducted Tuesday night July 11th between the hours of 10 pm and 2am. This treatment reduced the mosquito population but unfortunately not below an acceptable nuisance level. Another district wide treatment was conducted July 18th between 10pm and 2 am. So far this season, there have also been two larvicide treatments in May and June and one district wide truck treatment this past Tuesday. We realize the amount of mosquitos is difficult to experience but we ask for your patience as we work through the process of abating the mosquitos.

We strongly recommend using the mosquito hotline number to register high levels of mosquitos, any standing water near you and if you would like to be added to the list of people to notify of when truck spraying occurs. 1 800 942 2555. Please keep in mind there has been a very high volume of calls. Citizens may also contact by email to

The Freeport District has a contractual mosquito control arrangement with Clarke, a global environment products and services company.


To watch an overview of Clarke’s Integrated Mosquito Control Program:


Clarke’s Municipal Responsibility

To protect public health and comfort.

To prevent new breeding sites so residents can use and enjoy their backyards and other municipal recreational facilities.

To abate existing mosquito breeding sources.

Breeding sources we control are created by standing water, which may be found in street catch-basins, subdivision drains, roadside ditches, flood channels, ravines and other public rights-of-way. Routine larviciding done as necessary throughout the season, will keep these areas mosquito free. It is our responsibility to work with whatever local, state, or federal agencies may be involved to keep these areas abated.

Property Owner Responsibility

Your responsibility as a property owner.

To clear your property of any potential breeding sites.
To prevent any problem areas from reoccurring.

Mosquitoes are an all too familiar summer nuisance. They are not only annoying, but they can be transmitters of West Nile Virus, St. Louis encephalitis, malria and yellow fever to humans, and heartworms to pets.

Yard & Home Checklist

Get rid of old tires, tin cans, buckets, drums, bottles or any water holding containers.

Fill in or drain any low places (pebbles, ruts) in the yard.

Clean gutters periodically.

Keep drains, ditches, and culverts clean of weeds and trash so water can drain properly.

Cover trash containers to keep out rain water.

Repair leaky pipes and outside faucets.

Empty plastic wading pools at least once a week and store them indoors when not in use.

Make sure your backyard pool is properly cared for while on vacation.

Fill in tree rot holes and hollow stumps that hold water with sand or concrete.

Change the water in bird baths and plant pots or drip trays at least one a week.

Keep grass cut short and shrubbery well trimmed around the house so adult mosquitoes will not hide there.
