pesky pests

will help prevent attack; spray with derris, malathion or systemic insecticide as soon as the first signs are seen" Hope that helps a little I think that Provado Ultimate Bug Killer should get it. Derris is no longer available; I'm not sure about malathion by john cairns

slugs and snails

in my garden have tried sprays derris dust going out in the dark but i have hundreds of them . Earwigs like damp conditions. You could try a moat of dry material to keep them off your plants. Not 100% as they can fly. Try rolling up newspaper and wet by rosie plum
