Dealing with Chafer Grubs

There are two main species of Chafer Grub that cause problems in turf and sports surfaces: the Garden Chafer Grub (Phyllopertha horticola) and the Cock Chafer Grub (Melolontha melolontha) The ones shown to the right are the garden Chafer which is much smaller than the Cock Chafer with the larvae growing to 15mm in length. These will generally last for one season in the soil whereas the much larger Cock Chafer will last up to three years growing to quite a size (up to 30mm in length).
