Chafer grubs are a common lawn pest in the UK and can cause significant damage primarily by eating grass roots. Secondary damage is made by animals and birds digging for the grubs. Our nematode treatments provide a safe and natural way to rid your lawn of these ugly pests!
The timing of applications is vital when using nematodes, this ensures you are targeting Chafers at optimum times to gain control. We have a list of FAQs below to help point you in the right direction. Full and easy to follow application instructions are provided on delivery.
*Please note Nematodes are living creatures and as such are perishable. For best results please order only when you are ready to apply the product.
For best control we advise using two applications of nematodes each year, once in the spring and once in the summer. You should closely monitor soil temperatures and the presence of Chafer Grubs in the soil to time these applications.
We recommend applying nematodes in the spring only when you observe chafer grubs in the soil and soil temperatures are over 12 degrees celsius. This is generally between March and May (UK weather dependent). Use a soil thermometer to gauge this accurately as soil temperatures are different to air temperature!
We advise a summer nematode application between July and October. You should aim to apply the nematodes as early as possible within this period as the grubs are more vulnerable when younger. Again ensure you have found grubs in the soil before application.
If your lawn has suffered severely from chafer damage and the number of grubs in the soil is high, multiple applications will be needed to gain overall control. Consider applying nematode treatments spread out every 2 weeks in the summer period. You cannot overdose with nematodes and a surplus will not cause damage to your lawn or any other wildlife.
Consider using our Chafer Beetle Trap between May-June to help reduce the number of breeding adult beetles. This will contribute to the overall reduction of chafers in your garden!
To help your Nematode treatment we always advise you to spike and scarify the lawn before application. If there are bare patches and poor grass coverage, spiking the ground is especially important. The lawn also needs to be kept moist for nematodes to penetrate the soil and reach the chafer grubs, continue to keep the lawn moist for around 2 weeks after application.
Like good food, our nematodes are always best when ordered fresh! For that reason we advise you place your order only when you are ready to apply. Our nematodes do come in a unique gel formulation which does allow storage at 4 degrees celsius for up to 2 weeks, however as stated above, they are always best fresh.
Yes. Nematodes are completely safe for humans and pets!
