Who we are

At Milfoil Mercenaries, we’re on a mission to liberate your waterfront and ponds from the grip of invasive weeds with sustainable solutions.

Founded by Conner Johnson, a lifelong Seattle resident with 20+ years of property management experience. He started the business to assist family and friends with lake weeds, and has gradually scaled through referrals.

Our battery powered WaterShark harvester efficiently cuts and collects invasive weeds.

Friendly, professional, and fully insured, our team shows up on time to restore your shoreline with no chemicals, no hassle, and no excuses.
