Summertime brings fun in the sun, but it also means pesky critters which can be annoying, and even dangerous. Cottleville contracts with St. Charles County Environmental Service for Mosquito control. If you need to request additional mosquito control in your neighborhood please submit your request using this online form.

Mosquito safety is as easy as A, B, C, D...
Avoid bites---use insect repellent!
Be safe---always follow the repellent label instructions!
Cover up---wear loose, light-colored long sleeves and pants!
Dump---remove standing water around your home to reduce mosquito habitat!

The best way that citizens can help, is to eliminate breeding grounds on their own property. Clogged gutters, potted plant trays, buckets and lids, old tires, garden ponds, etc. are an oasis of breeding grounds for mosquitos!

** Please visit  St. Charles County Mosquito Control Program, for more information.

These are authorized choices to use for "Cottleville, Mo" residents followed by your accurate zip code on all of your mail AND your Missouri Driver License or ID card. The United States Postal Service Postal approved using "Cottleville, Mo" many years ago for all Cottleville residents.

Having identification with your correct and current City name is very beneficial to you as a motor vehicle operator and as a consumer.  

Don't pass up your next opportunity to renew your license or ID card with your "Cottleville", Mo address printed on it followed by your current zip code.

All City of Cottleville residents AND businesses should be using
"Cottleville, Mo" followed by their accurate zip code as their City identification, for their permanent address on all utility bills, as well as ALL other mail.  Using the correct City identification (Cottleville, Mo) with your accurate zip code could help save YOU money as Cottleville tax rates are often less than neighboring cities!

*Taxes collected and dispersed are often based upon a City zip code.  For example, if you are a Cottleville resident and are currently using
"St. Peters, Mo" or "St. Charles, Mo" or "O'Fallon, Mo" as your address, you MAY be paying a higher tax rate on your leased vehicle, purchased vehicles, phone bills, utility bills, online purchases, cable bills, gas bills, electric bills, water bills, and other invoices, etc.  As a result, you may lose money AND the City of Cottleville may also lose the tax revenue to the wrong City listed on that bill or purchase.  Those taxes are used to provide vital services such as parks, police, street repair, street lights, side walk repairs and so on.

It is important to note this advisory by the United States Postal Service:  
To avoid mail delivery delays, you must always use the correct City and zip code on your mail.
