Damage

Symphylans feed on roots of many crops and weeds. They may damage seedlings before or after emergence and may slow the growth of larger plants. They are associated primarily with moist, organically rich soil, and feed on decaying as well as living plant material.

Solutions

Garden symphylans are difficult to manage. Flooding for 3 weeks can limit the problem in some situations if your soil will hold the water. Vigorously disturbing the soil when it is dry just prior to planting by rototilling may reduce populations through abrasion of the pest's soft body.
