Nemasys® Chafer Grub Killer - Garden Chafer Grubs can devastate a lawn as they often infest the same lawn each year, so numbers increase un-noticed. Control chafer grubs naturally by treating with with Nemasys® Chafer Grub Killer when they are discovered (and the soil temp is 12c) or apply when they are at their most destructive i.e. in the spring (April) and Autumn (Sept).
N.B. Nemasys® Chafer Grub Killer needs a soil temperature of 12c and will NOT work at lower temperatures. It is also a perishable product (it will keep for 2 weeks in the fridge), so any orders will be treated as PRE-ORDERS and will be despatched later in the spring / autumn 2017.
Chafer Grubs - 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. Chafer Grubs are creamy coloured, approx 1.5 cm in length, have distinctive legs and will be found in the grass roots. They are often mistaken for vine weevils - but vine weevil tend to be smaller and do NOT have legs. Like leatherjackets, chafer grubs attack the grass roots causing identical symptoms, but chafers are larger and creamy coloured, making them easy to identify. 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. Here are some pictures of a customer's lawn with a bad chafer grub infestation :-
Chafer Grubs - The Garden Chafer Beetle emerges in May/June from the lawn and mate before laying eggs - if you are seeing adult beetles then you need to wait until September to treat when the grubs emerge again. 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.
N.B. The garden chafer is the most commonly found chafer grub and is very susceptible to nematodes, but there are other minor species e.g. Welsh and Summer Chafer which are less susceptible, so if you have treated and the grubs are still active after 4-6 weeks, please contact Green Gardener (firstname.lastname@example.org) for advise on what to do next. If you are looking to treat a large area, please seek advise 1st on trying to identify which species you have.

Nemasys® Chafer Grub Killer - Nemasys® Chafer Grub Killer should be applied to a moist lawn (we recommend pre - watering) on a dull day or in the evening. After application you MUST wash the nematodes into the lawn by watering heavily with a hose or a sprinkler. To apply, simply mix the nematodes with water and apply with a watering can or hose-end feeder PLUS economy packs can also be applied with a sprayer. Once applied the nematodes will seek out the chafer grubs. On contact they enter the grubs and destroy it. Having destroyed the grubs ,the nematodes multiply and are released back into the soil to hunt down more chafer grubs.
