Can Orthene be used as a deterrent for crayfish?

I havery a back yard that is close to a creek. I think the crawfish/crayfish got into my yard from there. Now they have jacked up my yard and about 40 holes and mounds and some areas I sink down. Can I use this as a deterrent.? How do I apply to my yard. Nothing edible is in the yard.


Orthene 97 Spray Insecticide is not a deterrent and would not be recommended for this use or in the yard as it is not labeled for this.  There is no product that is labeled for crayfish. If you see crayfish, the water table is very high and the usage of ANY insecticide can lead to poisoning the local water supply. The Tomahawk Model 405 is a double door crayfish trap that could be used.
