I live in Coburg in Lane County and am trying to reseed my lawn. My existing lawn was dying off in patches and I also had crabgrass taking over so I killed it all with round up and am attempting to reseed with a mix or rye and fescue. My seedlings seem to sprout like normal, but are soon killed off or eaten by something. I have lots of wormlike insects and have assumed them to be crane fly larvae. Can someone help to identify them. see the pictures. I have applied several doses of Sevin to the lawn but these worm like critters keep persisting. Any recommendations?
