Homeowners often find themselves bewildered by the speed and extent of the destruction which may ensue ...
However, white grubs (reaching 40–45 mm long when full grown) live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens, and golf courses. An obvious indication of infestation is the presence of birds, such as crows, peeling back the grass to get to the grubs.
In August, when the grubs are close to the surface and feeding, they are vulnerable to infestation by milky spore. This is also the optimal time frame for turf inoculation or applications with milky spore to increase milky spore in the soil environment (there are product specific guidelines that should be followed for milky spore application).
The grubs develop in the earth for three to four years, in colder climates even five years, and grow continually to a size of about 4–5 cm, before they pupate in early autumn and develop into an adult cockchafer in six weeks.
