Leatherjackets in lawns

[picker]

My lawn is looking sick and on checking under ground I found lots & lots of chafer grubs.My lawn book says treat it in Autumn but is there anything I can water in now.

Chafers live in the soil for up to three years you can have more than one generation in the soil at any given time. Control them by applying an insecticide as soon as you have performed a positive identification, usually in the growing season – April to September. Prevention is always better than cure so once one application has been performed, repeat annually in the if repeat outbreaks are common particularly in light sandy soil areas.
