Do Chrysanthamums Really Keep Mosquitos And Insects Away And If So What Does It Keep Away

Question

do they have bulbs that have to be dug up in winter or do they come back in bloom when spring

Answer 1

Partly. Pyrethrins in the Chrysanthemum are a spot killer. They don't do much once dry, though, except for pests that ingest it.
