Crayfish Control

Scientific Name: (Family)  Astacidae

Damage

  • small burrows in turf areas
  • newly planted rice;
  • eat baitfish and small game fish or their eggs.

Sometimes the damage can be quite severe. Note the photo below, where a crayfish, living in the soil below, dug its way up through a newly laid rubber surface in a newly established playground. Damage to the surface came to over 20,000 dollars. Photo courtesy of Gina Scheller.
