What Are Chafer Nematodes?
Chafer Nematodes are microscopic worms which are found naturally in your soil but by applying the nematodes you are increasing the levels. The nematodes attack the chafer grub larvae and quickly and safely kills them. The nematodes then reproduce to move on to find it's next prey.
It can take up between 7-21 days to see the benefits from using chafer nematodes however you should notice a significant reduction in the number of grubs within the first two weeks.
How to Apply?
Nematodes are very easily applied by dissolving the pack in water and distributing the nematodes evenly across your area by either using a watering can or a miracle grow applicator. Full instructions and dilution rates are provided and can also be found on the product images.
Nematodes are a live beneficial organism so have a short shelf life of around two weeks. We advise ordering the nematodes when you wish to use them. If you don't use them straight away they need to be stored in a fridge and used before their expiry date.
When to Apply?
The soil temperature needs to be above 12°C for the nematodes to be effective.
The optimum time to apply chafer nematodes is between August and September. This is when the young larvae are most susceptible to the nematodes and are most active. They are closer to the surface which makes it easier for the nematodes to seek our the larvae.
However should you have an extremely bad infestation, many customers do an earlier application as well in April/May.
Applying outside of the recommended time frame may still aid the control.
The soil temperature is generally warmer than the air temperature so the nematodes can survive the odd frost and slightly lower night time temperatures.
Don't apply in direct sunlight, ideally on an overcast day or in the evening. Keep the soil nice and moist for at least two weeks after the application. The nematodes thrive in wet conditions.
