Apply Nemasys Chafer Grub Killer to moist lawns from the end of August to early October. This is when the young grub larvae
are active and the temperature is above 12ºC (54ºF).
Immediately after applying the nematodes by watering can or plant feeder (click here
for detailed instructions), 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 later than October, since the grubs start to move down deeper in the soil and become inactive until the following spring.
The lawn can be used after applying Nemasys Chafer Grub Killer, which is harmless to children, pets and wildlife. See www.nemasysinfo.co.uk for more information.
The nematodes (Heterorhabditis sp) 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.
There are two pack sizes of Nemasys Chafer Grub Killer. One treats up to 100m2 and the other up to 500m2.
