How To Kill Lake Weeds

Aquatic Herbicides are one popular method of killing lake weeds. It does work, but only short term. Some of the problems with aquatic herbicides are that you actually are poisoning the lake. Who knows what other damage is caused to the lakes ecosystem.

Aquatic herbicides are very expensive and will need to be re-applied at least once every years. If you are planning on using aquatic herbicides for aquatic weed control, be sure to contact contact your local Department of Environmental Quality because you may need a permit.

Many people try to manually remove lake weeds by mowing, raking or another similar method. While this process may work in the short term, there are some serious downfalls to this form of lake weed control.

The biggest problem with this method is that when the plants are cut or broken up, they fragment. These fragments will settle again in the bottom of the lake and grow back even more invasively often times within the matter of a couple of months.

A method that was more popular but is being used slightly less now is adding grass carp to lakes to kill off the lake weeds. Unfortunately, the fish is considered an invasive species yet many people still use it.

Basically, grass carp are added to lakes and they eat the weeds. The fish that are added are sterile so they should not reproduce. On certain occasions, the fish work well, especially for very large applications, but in others they either fail to eat enough of the weeds, or they eat too much of the weeds and other underwater plants which is actually bad for the lake.

After reading the lake weed control solutions above, you may still be wondering how to kill lake weeds in a safe and effective way. The answer is the LakeMat.

The LakeMat basically acts like a lake bottom blanket. It is a mat that is easily placed on the bottom of the lake where the weeds grow. The mat blocks the sun from reaching the weeds which safely kills them off. The mat does not allow light through, but it does let gas pass through which prevents build ups of gas forming pockets below the LakeMat.

After just a few short weeks, the area under the LakeMat is free of weeds and you can then rotate it down the lake short to extend your weed free swimming area.
