I have a fern that is similar to a Crows Nest; however, the leaves do not curl. They are very dark green and throw a "I will say flower" long stem that appears to have brown spores. Best I can describe it. A pest is eating the foliage. I have tried just about everything on the market, still something is attacking this plant. Would you please advise what I can do to eradicate this pest? Every night I wrap a light weight lace curtain over the plant, and if for some reason I forget, well this beastly bug has a good dinner. Many thanks Mrs K Kemp P S I cannot show you a photo, I am not computer literate. KK

This could be slugs or snails, if you are not able to see the pests. Slugs come in the night and can devour plants.

If it is another type of pest, Neem Oil is a good treatment.
