Live in California. My lawn is well established, 15 years+. Noticed that
the lawn is dying in certain areas. I go to rake and the area comes up.
Something eating the roots. Lawn appears to be just laying on top of
soil. I have used Scott's Summer Blend fertilizer and followed up with
Ortho Diazinon a few weeks later with no help. Newer areas continue to
appear. Any ideas would be appreciated. Thank you, Steve T.

Did you water in the diazinon immediately? It only lasts for about
12 hours if it's in the sun, without irrigation.
