Q: My hanging ferns have been invaded with small white moths. They have just about killed the ferns by eating the leaves. What should I do?
A: Moths don’t eat leaves, their offspring (caterpillars) do the damage. Unusually high numbers of small moths have been noticed this fall. There are too many species to identify them all: webworms, darts, armyworms, etc.. Spray your ferns with any garden insecticide to control both moths and their leaf-eating children. They will disappear when night temperatures drop below 60 degrees.
