Nemasys® Chafer Grub Killer is the simple solution to control chafer grubs. The nematodes Heterorhabditis megidis seek out the chafer grubs and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey.

Apply to moist lawns during August and early October. This is when the young grub larvae are active and the temperature is above 12ºC (54ºF). Immediately after applying the nematodes, water the grass well so the nematodes are washed into the soil to reach the roots where the chafer grubs will be. Make sure the lawn does not dry out after applying nematodes. Keep the lawn well watered for at least two weeks.

Do not apply too late, since the grubs start to move down deeper in the soil and become inactive until the following spring. However, as this move downwards is temperature dependent, in some years it may still be alright to apply later. As long as the grubs are near the surface and the soil temperature is above 12ºC (54ºF) nematodes can still be applied.

PLEASE NOTE – An important condition for the proper use of beneficial insects (biological pest controls) is the correct identification of the pest. Although pests may look quite similar, the controls are very specific in the pest they target; efficient control critically depends on selecting the right biological pest control agent.
