If You See Something, Say Something

Wentzville is one of the fastest-growing cities in Missouri. As our community gets bigger, the Wentzville Police Department wants to remind residents to look out for each other. Sometimes residents are hesitant to dial 911 in situations that don't feel like a true emergency. However, these calls are an important part of the fight against crime. WPD needs residents to file reports so we can monitor crime trends and patterns. When we understand where and how crimes are being committed, we are better equipped to solve the problem. If you see suspicious activity (such as vandalism) or are the victim of a theft, don't wait. Contact the police immediately. When you take the time to report a crime as soon as it happens, we are all moving one step closer to increasing safety for Wentzville's residents and business owners. 

For more information, please call the nonemergency police line at (636) 327-5105.

Fireworks in Wentzville

The City of Wentzville wants everyone to have a safe and happy 4th of July. As we celebrate Independence Day, please remember to practice caution at all times when discharging fireworks. City ordinance allows fireworks to be discharged ONLY on July 3 and July 4 of each year, and only between the hours of noon and 11 p.m. each day. 

Please remember to be mindful and courteous of your neighbors when shooting off fireworks. Residents should take the following precautions to ensure that you and your family are celebrating safely:

• A responsible adult should supervise all firework activities. Never give fireworks to children.

• Light one firework at a time and then quickly move away.

• Always have a bucket of water and a hose nearby.

• Alcohol and fireworks do not mix. Save your alcohol for after the show.

• Dispose of spent fireworks by wetting them down and placing them in a metal trash can away from any buildings. Do not place fireworks in your plastic trash carts as they can easily melt.

Please note, fireworks are not allowed to be set off on City property including streets/sidewalks or cul-de-sacs or at any park within the City. To report illegal fireworks use, please call the nonemergency police line at (636) 327-5105. To learn more, please visit
