Buy Gardening Naturally Chafer Nematodes

Chafer beetle larvae attack grass roots. Grass growth slows and yellow patches appear. Grass is easily pulled up, with little or no root growth.Chafer beetles emergefrom the lawn. They lay their eggs, which hatch into grubs feeding on the grass roots before burrowing deep into the ground. They then lie dormant deep in the soil before moving to the surface in the spring to emerge as beetles again.

Wildlife, such as foxes and badgers, can also create a lot of damage as they dig up your lawn in search of grubs for food. Rooks, magpies, crows and woodpeckers feeding on your lawn are a good sign of a chafer grub infestation.

If the chafer's life cycle is not broken re-infestation occurs and the problem gets progressively worse.

Nemasys Chafer Grub Killer: - environmentally friendly and safe for children, pets and wildlife. No need to exclude children and pets from treated areas.

If you have just discovered Chafer Grubs in your lawn or had a severe infestation in the past, apply to moist lawns during April or May and in August to early October. This is when the young grub larvae are active.

Application in spring may aid control but August to October is the recommended time to apply. 

The nematodes come complete with instructions and can be applied using a watering can or nematode applicator. You just apply to moist soil when the soil temperature is above 10ºC (50ºF) and ensure the soil does not dry out for at least two weeks after applying nematodes. Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied the nematodes.

Delivery is completely free when just ordering nematodes. Should you purchase any other items then our standard delivery charge will apply.

Please note Nematodes are live material and cannot be returned. They will usually have an expiry date of around 2 weeks. The effectiveness can sometimes vary due to external factors.
