Can Nematodes Get Rid of Slugs?

Many people are unaware of nematodes and the benefits they have for gardeners. These are roundworms that are usually found in the soil. Nematodes can be used to get rid of slugs by killing them.

These worms release bacteria in their gut, killing slugs and insects in just one or two days. 

Nematodes work by entering the slug’s body through the mouth, anus, and any other openings. They will take over the body and release bacteria. Once the bacteria is released, it multiplies and causes death due to blood poisoning.

The bacteria feed on the tissue of slugs for nutrition. After consuming all the food sources, the nematodes will leave the body and search for a new host.

Will Nematodes Kill Slugs and Snails?

Yes, nematodes will kill both slugs and snails. One of the best things you can do for your garden is to use nematodes. These roundworms are beneficial to control the slug and snail population.

Nematodes work by entering the snail and slug bodies through their openings, eventually taking them over. Then, the nematodes will release bacteria which decomposes these animals from the inside and cause them to die. 

If you have slugs and snails in your garden, it would be best to use nematodes to kill them. 

How to Use Nematodes in the Garden

It is important to know how to use nematodes correctly so you can effectively get rid of slugs or any insects in your garden.

When you buy nematodes, it will help if you follow the instructions and look at the package. There are some measurements on the back for you to follow.

Aftercare is quite important when it comes to nematodes. You need to keep the soil moist for some weeks to allow the nematodes to move. 

Nematodes are quite sensitive to light, so you should never apply the mix under direct sunlight. Applying nematodes during the evening or on a cloudy day is best. In addition, you must ensure that you do not apply nematodes on edible plants, as people with weak immune systems can be affected.
