Cutworm Killer contains Steinernema species nematodes that can be applied as a soil drench to control and kill harmful soil dwelling caterpillars such as Cutworms. The nematodes will enter the larvae via a natural opening, like the mouth, and feed on the contents of the larvae. A natural bacterium is produced by the nematodes inside the larvae, which kills it. The nematodes also reproduce inside the larvae, releasing more nematodes into the surrounding area. Once the Cutworm larvae are killed, the nematodes die back to natural levels in the soil.. A natural pest solution.

Product Description

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.

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.
