When spraying a tree for elm beetles that is next to my pond do I need to worry about the over spray of Demand CS hurting my fish?
Yes, Demand CS like any other insecticide can be very lethal to fish. It would be advised to apply the product on a day that is not windy, and possibly even holding up a sheet of plastic on the other side of where you are spraying to protect overspray from going towards the pond. Also, apply on a day when it is not going to rain so the product has time to dry and bond to its surface so it does not run off.
