Just a heads up. Please DO NOT use Pyrethrins in your pond. Although they are one of the safest insecticides for mammals they are highly toxic to fish and other aquatic life! http://npic.orst.edu/factsheets/pyrethrins.pdf I don't have a good answer for a control product but I think Trish is right, if you spray them off it could help.

I have used in with success on terrestrial plants. You can find this at Lowes or Home Depot, here is a link to get you started. http://homeharvest.com/insectsprayspyrethrinbased.htm' Hope this helps!
