Hi Mariana –

Those white grubs in your strawberry plants are most likely the root-eating larvae (immature stage) of beetles or weevils. To control them using organic and natural methods consider the following:

In the early morning or late evening, shake beetles/ weevils from plants onto ground sheets and destroy.

Rototilling will kill the plump larvae in the soil.

Floating row cover (Harvest-Guard®) can be used as a physical barrier to prevent egg-laying adults from plants.

Spread beneficial nematodes on lgarden beds or mulch around plants to kill immature stages. These microscopic, worm-like parasites actively hunt, penetrate and destroy immature stages in the soil.

Surround WP (kaolin clay) forms a protective barrier film, which acts as a broad spectrum crop protectant for preventing damage from a large number of insect pests.

Azatrol EC contains azadirachtin, the key insecticidal ingredient found in neem oil. This concentrated spray is approved for organic use and offers multiple modes of action, making it virtually impossible for insect resistance to develop. Best of all, it’s non-toxic to honey bees and many other beneficial insects.

As a last resort, spot treat adults with botanical pesticides. Apply to all leaf surfaces and deep into the plant canopy where insects hide.

Good luck!
