corn ear worms

Question

i have seen some people put the red plastic drinking cups over corn silk to prevent moths from laying eggs, does it work?

Answer 1

It certainly sounds like it may work in keeping worms from entering the ears.
We suggest using a clothespin to do the same and it would not block as much sunlight.
