Since Eurasion Water Milfoil grows at a rapid rate, continuous removal and control is required to keep it a manageable level. There are various methods for the removal of Eurasion Watermilfoil. Herbicides are specialized chemicals that are able to only kill Milfoil and plants similar to it and letting the other native plants grow. In some areas along the shore people cover the water with a tarp so that the milfoil cannot get any sunlight, killing it after awhile. Another way is to cut them up with machines, it is possible hire underwater mowing companies. Since the plant can grow from just a piece of it this can actually lead to more Milfoil if the cut up pieces aren't gathered out of the water. Similar yet less effective, it is also possible to pull them out by hand. This should only be done if you're trying to temporarily remove it from a small area. (ecy.wa.gov)

What You Can Do: 

To prevent the further spread of Milfoil it is recommended to always check your boat's engines and sports equipment for any pieces of it when moving them from one body of water to another. Due to the plant's ability reproduce so easily, this is very important. If walking along the shore or on a dock, taking out floating Milfoil will help prevent the spread to other areas of the lake that don't have any growing there. If living, working, or involved near Lake Washington or any body of water, it is vital to monitor the growth of any Eurasian Water Milfoil to control it. By either pulling it by hand, grabbing it out with a rake or pole, or hiring a lake mowing company it is possible to maintain. (clean-flo.com)
