Combating pests with nematodes

What are nematodes?

Nematodes, also known as nematodes, are microscopic worms that live in the soil. They are known as the natural enemies of many harmful insects, including snails, grubs and vine weevil larvae. Each type of nematode is specialized in controlling specific pests, allowing you to control a pest effectively and effectively without disrupting the ecosystem. These small organisms are harmless to humans, pets and beneficial insects, making them an ideal choice for biological pest control.

How do nematodes work?

Nematodes work in a clever and efficient way. Once they come into contact with their prey, they enter the body through openings such as the mouth or skin. Once inside, they secrete bacteria that are deadly to the host. The pest insect quickly dies, after which the nematodes continue to multiply and explore the environment for new prey. The great thing about nematodes is that they regulate themselves: once the pest is eradicated, the surplus nematodes also die, maintaining a natural balance in your garden.

Benefits of nematodes

• Environmentally friendly:Nematodes are a 100% natural method that leaves no chemical residues.
• Specific action:Nematodes only attack the pest insects they are intended to target, without harming other organisms.
• Safe for humans and animals:They do not pose any risk to the health of people, pets or plants.
• Suitable for underground pests:Nematodes mainly control pests that live underground, such as larvae and leatherjackets.
• No chance of resistance:Because nematodes physically enter the pest insects, there is little chance of resistance developing.
• Easy to apply:Nematode treatment is easy to carry out and cannot be overdosed.

Which nematodes do I need?

Choosing the right nematode species depends on the pest you want to control. Here is an overview of the most common nematode species and their applications:

• Phasmarhabditis Californica– Best tested for controlling slugs.
• Heterorhabditis Bacteriophora– Very effective against grubs (beetle larvae).
• Steinernema Carpocapsae– Works well against mole crickets, cutworms and leatherjackets etc.
• Steinernema Feltiae– Recommended for fungus gnats, thrips and ants.

How do you use nematodes?

Using nematodes is simple, but there are some important steps you should follow for best results:

1. Timing:Nematodes do not do well in bright sunlight. Applying in the evening or on cloudy days is ideal.
2. Temperature:Check the soil temperature before applying the nematodes. Each species has its own ideal temperature. This is how it worksHeterorhabditis Bacteriophorabest between 12-33°C, whileSteinernema Feltiaethrives between 8-33°C.
3. Humidity:Keep the soil moist before, during and after treatment for at least two weeks. This helps the nematodes spread and do their work effectively.
4. Dosage:Always mix the nematodes with water according to the instructions on the packaging. It is not possible to apply too many nematodes.

Practical tips

• Save:Store nematodes in the refrigerator (not the freezer) and use them as soon as possible after purchase for best effect.
• Application:You can apply nematodes with a watering can or sprayer. Make sure you spread the nematodes evenly over the treated surface.

Why choose nematodes?

Nematodes are the natural ally for a healthy garden without pesticides. They are easy to use, effective and above all safe for the environment. By choosing nematodes you contribute to a greener future, in which we can combat pests without harmful chemicals.
