The only real pest mustard spinach is susceptible to is a flea beetle (there are many types, including a spotted species), which is hard to control. Protecting plants with barriers such as a row cover before infestation is the best management strategy. Before putting the garden to bed for the winter, remove all old debris from your infested plants. Since flea beetles overwinter in the soil, try hoeing and cultivating in the early spring to destroy the larvae. Add a thick layer of mulch around young plants to prevent the beetles from jumping up on to the leaves. Place some sticky traps nearby to try to capture those that persist.
