With over 25 years of aquatic experience treating lakes in Wisconsin, we pride ourselves on doing a superior job, while preventing the spread of invasive plants. We are a family owned business, and will continue to  develop long term relationships with the local Wisconsin DNR officials, lake districts, and lake associations. Our GPS/Guidance System enabled application equipment includes two conventional outboard boats, which will apply liquid or granular herbicide evenly over any body of water. Schmidt’s Aquatic is licensed, state certified, and fully insured in the State of Wisconsin to apply herbicides to the waters of our great state. We believe the key to our customer service has always been providing prompt, reliable, quality service at a fair price. When you dial our phone number, you speak directly to the owner. This helps us provide efficient and effective quality service. We look forward to hearing from you, and helping your lake to control and manage aquatic plants, while improving and creating environmental, social, and economic benefits for all lake users.
