Hi Charlene:
Sorry to hear about your Scots pine trees -- this species can definitely struggle here in Illinois!
I would strongly encourage you to reach out to a local resource such as your local IDNR district forester, Mr. Dave Griffith (dave.griffith@illinois.gov) or your local UI Extension Office. Most UI Extension offices have a horticulturist and/or Master Gardeners available to provide assistance to homeowners:

Best of luck!
