While the damage is done by the root maggots, or larvae, and not the adult flies, for effective control. One of the most reliable control methods now in general use is to plant seeds that have been treated with an appropriate insecticide. Parasitic nematodes and parasitic fungi also reduce root maggots. Adjusting the planting schedule of susceptible crops in order to avoid root maggot peak times is another way to prevent an infestation.
