Aquatic Millfoil

Aquatic Weed Control specializes in the control and disposal of aquatic noxious weeds in the Pacific Northwest. These weeds interfere with swimming, boating and fishing. They may not be native to the region and harm the environment by choking out native water plants, fish and other marine life.

Our professional teams reclaim water properties affected by these destructive weeds, employing a variety of environmentally sensible methods.

We perform a cost effective, lasting, and practical solution to your aquatic weed problem while working being compliant with local, state, and federal regulations.

Homeowners have not had an effective means of fighting infestation of their waterfront by aquatic weeds (usually milfoil or lily pads). They have tried raking them or dragging chains over the weed bed to break off the weeds. Besides being difficult, these methods just worsen the problem because each fragment of milfoil is capable of rerooting as a new plant. The result is increased weed proliferation and the spread of the weed problem to adjoining properties.

Eventually the weeds win and life along the water loses much of it attraction. Few people enjoy swimming in weeds.  Jet ski intakes and boat propellers become fouled. Sport fishing declines as the milfoil chokes off the natural habitat.

Aquatic Weed Control offers cost effective solutions to homeowners:

· Our innovative AquaScreen installations are an effective mechanical control technique. They prevent the weeds from getting light, creating a totally weed free area around your dock.  Using our eight years of experience, Aquatic Weed Control has developed a proprietary AquaScreen system to make installation and maintenance of the barrier much more effective.
· Aquatic Weed Control also offers mechanical harvesting and bio-mass removal upon request. Similar to mowing your lawn, this method cuts noxious weeds to a depth of 7 feet allowing full enjoyment around your dock and shoreline.
· Lastly, at the request of many of our clients, Aquatic Weed Control now offers environmentally responsible herbicidal treatments for the control of various noxious aquatic weed infestations.

The basic AquaScreen installation includes four panels and covers about 300 square feet.  The service includes a midseason maintenance check in July and minor repairs or maintenance requested throughout the season.  Service contracts are annual and include:

· Installation of the first 300 square feet: $500.00
· Additional AquaScreen over 300 square feet: $0.70 per square foot

Any client has the option of cancelling the service after each season and before the ensuing season, at no additional cost.   Upon cancellation, AWC would remove all the AquaScreen and return your waterfront to its original condition.  However, the client has the option each year to sign up for an annual maintenance program.  This includes:

· A midseason maintenance check in July and also addressing any additional minor maintenance issues requested by the client throughout the season
