I had three pots that I had put snowdrops in over the winter. Two weeks ago I was transplanting the snowdrops to an area of the lawn when I found about forty or fifty little larvae in the compost from the pots. At the time I had no idea what insect these were from but collected them up and put them on the bird table. Was doing a bit of weeding in the beds tonight and spotted 3 vine weevils. Having looked up the internet I now recognise the grubs I found a few weeks ago as vine weevil larvae. A lot of the info I have found on the internet seem to have mixed messages as to whether you should actually do anything or not to get rid of them. They say that the insecticides used to kill the grubs and adults eating the plants can also be transferred to bees through nectar, killing the bees. Some seem to think the damage the vine weevil does is minimal compared to the effect of the insecticides. I'm a bit lost as to whether to just leave it and accept they are in the garden or whether to do anything about it. Anyone got any ideas or other less harmful remedies that work?

The adults feed on leavesof many types of leafy plants, trees and shrubs while the larvae feed on the roots. I have a few of the critters haunting my strawberries at the moment. Organically the only solution is to catch them usually at night and destroy them, there is a parasitic nematode that can be turned loose on them also called " Heterorhabditis spp " . Using a chemical usually has a knock on effect on some other bug that could be beneficial and I would try to stay organic if possible.
