Maybe there is just one F. Anyways the grubs were recently brought to our area, and the skunks and crows are ripping up the lawns as bad as a rototiller might. It is an epidemic. Because the people controlling it back east doused it with diazinon and malathion it is now resistant. Seems to be unnaffected by all pesticides. I tried the predatory nematode on one lawn with no success. Chances are the people didn't water the lawn as well as they promised they would. Not my fault, but if they did then the nematodes did not kill the grubs. Does anyone know of a tried/tested way to kill the grubs?
