I had them in my potted blueberry plant and potted hydrangea. So I cut some weed mesh and put it on the soil, and topped it up with gravel. Those weevil grubs have remained trapped under the mesh for the last 6 months and plants are fine. no adults have appeared this year. Recommend it as a solution.
