We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for snails is 5 ppm copper sulfate. This too should be applied in a manner which thoroughly mixes the chemical in the pond.
