We had a lady send us a picture of what looks to be larvae type pest that has defoliated her little fir type of tree/shrubs. She would like to know what they are, how did they get on her tree/shrubs and what to use on them to get rid of them. She did spray them with Sevin and that seemed to kill them. Could they be "Redheaded Pine Sawfly"?

These are probably redheaded sawflies. Please see more information on redheaded sawflies at http://plantdiagnostics.umd.edu/level3.cfm?causeID=842 which addresses your questions.
