caterpillar ID?

caterpillar ID?

Hello everyone :) I need some help, I have googled and looked through all the appropriate tags but I can not ID this caterpillar that is eating my Boston Fern! I got them at the beginning of the summer when I went away for a weekend and I thought I had manually pulled them all off. I moved my ferns indoors for the winter at the beginning of this week and they exploded again, I have pulled at least 4 a day off for the past 3 days. I am not good at plants but I am really attached to my ferns! My husband bought me Ortho Max Lawn and Garden Insect Killer but I am not sure if it would work, it does not say anything in there about ferns specifically; is it ok to use? Would diatomaceous earth be better for killing them without hurting the fern? I am in middle NC. TIA for your help! They get darker as they get older, a couple of the ones I pulled off at the beginning of the summer were black, the younger they are the more green they are:
  • Barbara

    I don’t know what they are but I have the same problem with my fern.
    If you find out please let me know.
    Thank you
