Vine Weevil are out and about. Protect your potted plants !

Vine Weelvil are insects which eat plants leaves and its Grubs eat plant’s roots which kill the plants. I have caught them eating my plant’s leaves in our garden. I have killed them instantly. They already have damaged our all Lilly plants which are planted on pots. I had been investigating for two weeks that what was eating the leaves of  our Lilly, and finally I caught them yesterday. Must act now, protect your plants. What is Vine Weelvil and how to eliminate them ?
