The soil dwelling grubs can be difficult to control with chemical insecticides and products showing some efficacy, such as chlorpyrifos have been withdrawn from many markets: especially garden centres.
 Besides their environmental benefits, certain 'cruiser' entomopathogenic nematode species (also see below) have the additional capacity to search for their prey underground.

Adult weevils can be controlled by using sticky barriers on the trunks of affected plants, as the weevils return to the soil each day.

Adults can also be manually removed from plants at night when they can be found feeding on leaf edges.
 Use only a dim torch or candlelight to search by, as they will drop to the ground if startled by bright light.
