Root aphids and mealybugs damage to roots of plants by sucking the sap in the roots often causing wilting and discoloration of the plants.
Root aphids are similar to above ground aphids but feeding on the roots instead of leaves and stems. E.g. The lettuce root aphid is a soil dweller that attacks lettuce roots in spring and summer, causing lettuce plants to wilt and occasionally die.
Root mealybugs are common in containers and well draining soils. The mealybugs have a thin, uniform waxy coating and lack the terminal wax filaments typical of their foliar-feeding relatives. Large white fluffy patches may develop on the roots.
