How do I recognize vine beetles?

Adult vine beetles emerge around May. The beetles are 7-10 mm long, brown-black in color with light spots on the back. The beetles cannot fly and can be found on leaves at dusk or at night. During the day, for example, they hide in plant pots or under pieces of wood.

How do I combat vine weevils?

You can combat vine weevil larvae in the soil using nematodes. Felti nematodes can be used in spring and autumn to penetrate and kill the larvae.
