WHO:     The St. Charles Community Development department initiated the city’s 2009 mosquito  spray schedule on May 11.  The city currently operates three fogging machines to cover the citywide weekly schedule between the hours of 7 and 10 p.m.

WHAT:   The city’s program to help control the public health annoyance caused by mosquitoes utilizes a product named Evoluer 4 - 4 ULV. This product is applied in each Ward of the city once a week using truck mounted sprayers. The product does not pose a health risk to humans or animals; however we recommend you take reasonable steps to avoid the fog when possible. Appropriate steps include the following:

. Close the windows of your vehicle if you are following a mosquito spraying truck.
. Keep yourself and children out of the street until the fog settles or dissipates.
. Wash skin and hands if irritated by direct contact with the chemical.
. Do not attempt to stop or get the attention of the mosquito truck operator. The trucks are  calibrated to distribute the proper amount of chemical.
 
WHEN:    The citywide, weekly spray schedule for each Ward in St. Charles is as follows:
               . Mondays -- Ward 1, Ward 2 and Ward 3
               . Tuesdays -- Ward 6*, Ward 9* and Ward 10*
               . Wednesdays -- Ward 4, Ward 5 and Ward 8*
               . Thursdays -- Ward 6*, Ward 7, Ward 8*, Ward 9* and Ward 10*
* Denotes partial -- residents with specific schedule questions should call Community Development at 636-949-3222.

ALSO:  There are additional steps all residents can take to help prevent mosquitoes from breeding and becoming adults. We ask that everyone follow these guidelines to prevent mosquitoes from becoming a nuisance to you and your neighbors.

. Eliminate all standing water from areas on your property.
. Remove water from tires, buckets, and other items that collect water.
. Don't dump grass clippings, branches or other items in storm drains or ditches.
. Fill holes in trees with sand or mortar.
. Scrub and change the water in bird baths weekly.
. Empty and refill pets' water pans daily.
. Empty any small plastic wading pools weekly. Store it indoors when not in use. Properly maintain your swimming pool and keep it covered so as not to collect rain water.
. Contact the City of St. Charles (636-949-3227) if you know of large bodies of stagnant water, this way we can take appropriate steps to eliminate the water.
