Nematodes are popular biological control agents against garden pests. But how deep do they actually penetrate the soil? And do they even reach the roots of your plants to combat harmful larvae? In this blog post, we'll literally delve into the soil and discover all about the depth at which nematodes are active.
How deep can nematodes penetrate into the soil?
Nematodes move through the soil in search of their prey. All species can penetrate up to 30 centimeters into the soil. This is important because many pests, such as the larvae of vine weevils and leatherjackets , live at this depth.
The precise depth that nematodes reach depends on several factors:
- Soil structure : In loose, moist soil, nematodes can move more easily and penetrate deeper. In compact, dry soil, they have more difficulty moving.
- Moisture : Nematodes depend on water for movement. In dry soil, they stay closer to the surface, while in sufficient moisture, they can go deeper.
- Temperature : Most nematodes are active at temperatures between 10 and 25 degrees Celsius. In colder periods, they move more slowly and tend to remain in the upper layers of the soil. Check the official website of the Royal Netherlands Meteorological Institute (KNMI) to check the current soil temperature .
Do nematodes reach all pests underground?
Yes, nematodes can penetrate deeply enough to control many underground pests. They penetrate the larvae, paralyzing and killing them within a few days. This makes them an effective and natural way to control pests without harmful chemicals .
How do you ensure that nematodes are properly absorbed into the soil?
Want nematodes to do their job optimally? There are a few things to keep in mind:
- Moisten the soil: Nematodes need moisture to thrive. Water the soil before and after introducing nematodes .
- Ensure good soil structure: Loose soil helps nematodes penetrate deeper. Avoid hard, dry soil.
- Use the right nematodes: There are different types of nematodes, each with its own specialization. Choose the right species for the pest you want to control.

Nematodes work deep in the soil
Nematodes can penetrate the soil up to 30 centimeters deep , provided the conditions are right. This makes them excellent for controlling underground pests. By keeping the soil moist and loose, you help them do their work effectively. This way, you naturally protect your plants from harmful larvae and other unwanted creatures!
