All About Nematodes - Your Questions Answered

Gardening Naturally answer their most frequently asked questions about nematodes, including what they are, how they work and how to use them in your garden or allotment.

What are Nematodes?

Nematodes are an organic, natural way of controlling many types of pests, helping you to manage infestations without the use of harmful and unnatural chemicals. Nematodes are microscopic worms that can be found in the soil.


How do Nematodes work?

You will require the specific type of Nematodes for the pest you are looking to control. For example, slugs, leatherjackets or vine weevils. The way that Nematodes work differs depending on type.

Slug Nematodes feed and multiply inside the slug until it stops feeding and disintegrates.

Vine Weevil Nematodes work by seeking out and killing vine weevil larvae.

Ant Nematodes encourage ants to move their nests elsewhere as ants cannot tolerate the nematodes being near their nest.

Leatherjacket Nematodes seek out the leatherjackets and attack the pest by entering natural body openings, releasing bacteria that stops the pest from feeding and quickly killing the pest.

Chafer Nematodes actively search for white grubs present in the root zone, the nematodes then multiply inside the grub until it decomposes.
