|14. Controlling Aquatic Pests
As a general rule, insecticides should not be used in or near the water because they can harm fish and other beneficial aquatic life. Problems do arise, however, and they must be dealt with or you run the risk of losing expensive plants. As with other garden plants, pests are usually specific to varieties. The same is true with aquatic plants. You should watch for Aphids, China Mark Moths and False Leaf-mining Midges on your aquatic plants.
