Chafer Grub Killer Nematodes
Chafer Grub Killer nematodes are of the species Heterorhabditis bacteriophora that enter and kill the Chafer grub larvae within a few days.
Chafer grubs are a pest of lawn and grass areas that feed off the roots. This causes large lawn areas to turn yellow and attract birds and animals to rip up the grass to eat the grubs.
Nematodes are a natural pest control which require warm soil conditions to be active. This means that they need to be applied in summer/early autumn.
The nematodes are supplied in a gel formulation which keeps them of high quality in storage and delivery. Suitable for storage in the fridge for up to 6 weeks if unopened.
PLEASE NOTE - As these are live creatures, they are bred in batches to be as fresh as possible and so your nematodes will be prepared to order and despatched in approx 5 working days depending on demand.
Chafer Grub Killer can be applied with a watering can, Hose end feeder, knapsack sprayer or larger spraying equipment. Ensure that the lawn is moist at the time of application and the nematodes are applied with plenty of water.
More than one application may be required for heavy infestations. Strong sunlight needs to be avoided as nematodes are UV sensitive.
Storage of Nematodes
If you cannot apply immediately, store in the fridge (4 degrees Celsius) and use as soon as possible. Do not freeze. Use before the best by date.
Soil temperature must be above 12 degrees Celsius.
Results will be better if the lawn has been scarified and tined before application.
Do not apply in bright sunshine as nematodes are UV sensitive (evening is ideal).
Scarify and tine the lawn if possible.
Ensure the lawn is watered and moist before applying nematodes.

How long do the Nematodes take to work as I have to lay new turf?
Nematodes are a natural option for killing the larvae therefore, whilst very effective, you do have to allow time for the Nematodes to work. This means that you should allow a minimum of 2 weeks, after application, before laying new turf.
Is it easy to apply your Nematodes?
All you need to do is mix the Nematode pack with water and apply to your lawn. Each pack is supplied with easy to follow instructions and all you need is a watering can with a large rose which will allow the Nematode mix to flow.
