Usually, infested plants are weakened and have lower yields. It is also found in Mexico, Central America, and South America. Once root maggots have invaded a plant to feed, there is no EPA-approved pesticides to get rid of them. Since generations overlap and reproduction continues all year, the number of annual generations is difficult to determine.

After another two to four weeks, a new generation of adult flies emerges, and another life cycle begins. However, the damage caused by the seed corn maggots is sometimes difficult to distinguish from other problems. Because root maggots move around, it is not only imperative that you dont plant susceptible crops in the same location as the year before, but also that you plant new crops as far away from the location of the previous years crop as possible.

Planting susceptible crops in raised beds creates an environment that is less than ideal for root maggot eggs to hatch because they prefer cool, moist soil. Lightly infested leaves have pale blotches or spots showing through the leaf; heavily infested leaves turn completely pale and dry up. Seed corn maggot puparia can be found in soil throughout the year, and they overwinter in these puparia. The soil in raised beds warms up faster and earlier, and stays drier than in ground-level garden beds.
