In greenhouses or during mild winters, some feeding and egg-laying activities may continue. In addition, there are three factors that can foster root maggot infestations: A cool, wet spring with temperatures between 66 and 79 degrees provides ideal conditions for root maggot eggs in the soil to hatch. During periods of high humidity, fungus diseases also reduce populations.
