…Fat, white insect larvae are found in the soil near the roots.
Larvae (grubs)
Larvae (grubs) of various insects such as Japanese Beetles and Rose Chafers live in the soil for much of the year and will feed on newly planted strawberry, blueberry and raspberry roots, especially plantings following sod or on lighter soils.
Various grubs that attack berry roots are pictured.
Adult insects feed on plants, but their larvae feeding on roots cause much more damage.
Both rose chafers and Japanese beetles are insects that belong to the May Beetle and June Bug family. More Japanese beetle information.
