Nematodes against grubs: Natural Control and Prevention

Did you know that the use of chemicals to combat grubs is not legally permitted ? A very effective and environmentally friendly method to get rid of this pest is the use of nematodes. Nematodes, or nematodes, are very small parasites.

You can easily apply them by planting them in the soil. The nematodes will look for the grubs and penetrate the larvae. Within a few days the grub will die. The nematodes multiply and will eventually leave the body of the dead insect. After this they will look for new grubs. Because this method of control is so effective, most experiences with nematodes against grubs are positive. This high effectiveness is because the source is tackled. The first effects will be noticeable after a few days to a week. Perfect for plant lovers who want a green and healthy lawn.

Combat grubs with nematodes

Grubs are best controlled when they are still young (smaller than 2 cm); Then 80% to 95% of the grubs usually die in the weeks after treatment. As the grubs grow larger, the effectiveness of the control drops below 50%. That is why it is important to apply the nematodes at the right time, when the grubs are still small. In addition, it is important to provide plenty of water. The nematodes enter the soil together with the water and thus reach the grubs. Moreover, the nematodes die if it becomes too dry.

Which nematodes work best against grubs?

Heterorohabditis bacterephoria works by far the best against grubs. That is why we recommend using it. These nematodes do not tolerate cold well, they work best at soil temperatures

Applying nematodes against grubs

Mow the grass short first. Dissolve nematodes in water and then dilute according to the surface to be treated. Pour the mixture onto the affected areas with the watering can or spray with our nematodes and clean around there. If you have many bare spots, it is best to treat the entire lawn. Do not apply in full sun. Applying in the rain is ideal. Keep the surface moist for at least 2 weeks. Water deeply so that the substrate is moist. Treat several years in a row to break the beetle cycle.

When to combat grubs with nematodes?

The best period of application is mid-August - end of September. At that time, all beetle species have young larvae in the soil that can be controlled more effectively. In the spring you can only combat it if it is warm enough. The soil temperature must be at least 12°C for two weeks for the nematodes to work effectively.
