Eurasian milfoil is a notoriously invasive aquatic weed. It doesn’t just grow—it takes over, choking out native plants, reducing oxygen levels, and damaging water quality. And the biggest mistake many lake managers make? Spraying it with herbicides and thinking the problem is solved.
Here’s the truth:
Spraying doesn’t remove the plant—it sinks it.
When you spray herbicides, you’re not eliminating the weed; you’re just causing it to die off and sink to the bottom. That dead biomass becomes muck, which fuels more weed growth. Worse, milfoil fragments can regenerate, so spraying often accelerates the infestation by essentially replanting the weed at the bottom of the lake.
Mechanical removal pulls the problem out by the roots.
Using aquatic weed harvesters like Weedoo Boats, a trusted environmental workboats manufacturer, we physically cut and remove milfoil from the water—roots, stems, fragments, and most importantly, the seeds. That means we’re not just trimming the weed—we’re preventing its comeback.
No toxic runoff, no collateral damage.
Spraying introduces chemicals like glyphosate into ecosystems where fish, birds, pets, and people recreate. Mechanical harvesting? 100% chemical-free, with no downstream consequences.
Think of it this way:
Would you spray Roundup on your front lawn and leave the weeds to rot into the soil? Or would you pull them out and haul them away? The same principle applies underwater.
“Don’t sink the problem—remove it. Mechanical harvesting works where chemicals fail.”
