Chafer Bugs
Chafer Bug larvae can cause
devastating damage to lawns. Some of the damage is caused by
the grubs chewing at the roots of the grass, but much of it
is caused by birds and animals scratching away at the soil
searching for the juicy grubs.
Common Chafer Grubs are white grubs with a brown head, (see
lower picture), not unlike Vine Weevil grubs but with
distinct pairs of legs at the front end. Common chafer grubs
only reach 20mm in length. They are about the thickness of a
matchstick. If you see something twice this length it is
probably a cock chafer. Cock chafer are not susceptible to
biological treatment being tougher, and having a longer life
cycle. However it is the common chafer which is the one
commonly found in lawns.
Chafer Grub larvae hatch out to become flying beetles -
sometimes called May Bugs because they typically emerge in
mid May. Chafer Grub adults lay eggs in June which turn into
more Chafer Grubs in July to eat grass roots until October.
Then Chafer Grubs dig deeper into the soil over winter until
May before Chafer Grub surface to fly, mate and lay eggs
again.
Chafer Control
Falcon Pest Control use
biological methods which do not harm animals and birds to
control chafer grubs.
The best time for treatment is August to September, when the
freshly hatched grubs are present and are in the top few
centimetres of the turf, before they descend to
greater depths to hibernate for winter. |
