To squarely put curb mosquito populations during mosquito season, the City of Lewisville has started to offer free mosquito dunks to residents to reduce mosquito populations and the associated risks of disease transmission. This initiative, which involves distributing a unique kind of larvicide, aims to give homeowners a direct way to tackle the perennial battle against these pesky insects.

Citizens interested in joining the fray can now go directly to pick up these mosquito dunks at Lewisville City Hall, located at 151 W. Church Street, specifically at the Permitting Counter on the second floor. To ensure that these resources go to actual residents, you'll need to provide proof of residency via a government-issued ID or other forms, such as a utility bill or auto insurance paperwork.

But what exactly is a mosquito dunk? These nifty tools are effectively small, beige donuts that float on top of standing water. The City of Lewisville elucidates how the dissolving dunks gradually release a bacterium that's lethal to mosquito larvae yet harmless to other animals. Each dunk is engineered to cover up to 100 square feet of water and keep working for 30 days or more, making them suitable for use in a variety of settings, from birdbaths to elevator shafts.
