Chafer Grub Control

Chafer Grubs can devastate a lawn PLUS birds and animals digging up and pulling at the lawn to get at the grubs to eat can do even more damage. If your grass growth slows, yellow patches appear or if it is easily pulled up, with little or no root growth then check for grubs. Control chafer grubs naturally, by trapping the adult beetles with our Adult Chafer Beetle Trap and then apply Nemasys® Chafer Grub Killer to control the grubs.

Chafer GrubsChafer Grubs - Chafer Grubs are creamy coloured, approx 1.5 cm in length, have distinctive legs and will be found in the grass roots. Chafer grubs attack the grass roots causing the grass to yellow. Sampling your lawn to identify the pest - inspect discoloured areas of lawn by cutting a 6" X 6" section of turf on three sides and peeling back the sod. Examine the upper 2 inches of roots for white grubs. Shake the sample or probe through the soil with knife or screwdriver to dislodge the grubs. As the grubs will not be distributed evenly, examine other parts of the lawn to find out the extent of the infection. Spotting the adult chafer beetles will help you to identify the pest responsible for the damage, BUT always inspect the lawn for the grubs to be sure. Birds (magpies and crows), foxes &/or badgers attacking the grass in an attempt to eat the grubs will cause even more damage and is often the 1st indicator of a chafer grub infestation.

Adult Chafer BeetlesAdult Beetles - The Garden Chafer Beetle emerges in May/June from the lawn to mate before laying eggs in th lawn from where it has just emerged. These eggs hatch to produced chafer grubs. The eggs are often laid in the same place each year so the problem gets progressively worse. The Chafer Grubs feed on grass roots from July until late Autumn before burrowing deep into the ground to pupate. They are a source of food for large birds-crows and woodpeckers as well as foxes and badgers. These may do more harm to your lawn by ripping it up to get at the grubs. The Chafer Grubs then lay dormant during the winter deep in the ground before moving to the surface the following spring to emerge as beetles in May / June and starting the process again.
