Chafer Grubs damage roots and
underground stems of many plants during the winter and spring months as
they overwinter in the soil.
They are not a serious pest in any
part of the garden other than the
lawn - where they can do considerable damage. They can
however, do considerable damage to newly planted annuals and perennials.
Mature plants are rarely killed when in active growth.
The best control of chafer grubs is to
destroy them as they are bought to the surface by digging. together with
this, Starlings like a feast of Chafer grubs, so do not deter them from
digging away in the border.
If wilted plants are dug up and it is
found that the root system has been attacked, then it will be either
Chafer grub or Vine weevil
beetles that will probably be the problem.
Nemasys - a biological control based
upon nematodes can be used to control Chafer Grubs in the Lawn. Other
parts of the garden rarely need anything other than localised search and
destroy tactics.
There can be incidental damage caused
by the fact that you have Chafer grubs. If you live in an area where
there is a large badger or fox population, they love to dig the grubs
out for a tasty meal. As such, the damage that foxes cause by digging,
is often worse than the actual damage caused by the Chafer Grub!
