Although it is susceptible to some pesticides, it is usually recommended that home growers pick off beetles by hand, or shake them off onto a sheet of paper to remove them, if the plant affected by them is intended for culinary purposes.

Otherwise, they do not present a major problem to the host plants, although a large, long- term infestation can be devastating.
