How to Get Rid of Slaters on Fennel Plant

Updated: April 14, 2022

Fennel is an aromatic herb that belongs to the carrot family. It is a popular ingredient in Mediterranean and Asian cuisine, and its seeds are used as a digestive aid. However, fennel plants are often susceptible to pest infestations, one of which is slaters. Slaters are also known as woodlice or pillbugs and are related to crustaceans. They are not harmful to humans, but they can cause significant damage to fennel plants if left uncontrolled. In this article, we will discuss how to get rid of slaters on fennel plants.

Identify the Problem

The first step in getting rid of slaters on fennel plants is to identify the problem. Slaters are small, grayish-brown insects that are about 1 cm long. They have a segmented body and seven pairs of legs. They are often found in damp areas such as under rocks, logs, or mulch. When they infest fennel plants, they feed on the leaves and stems, causing damage to the plant.

Remove Debris

Slaters thrive in dark and damp conditions, so one way to get rid of them is to remove debris and clutter around the fennel plant. This includes any dead leaves, twigs, or mulch that may be lying around. This will help to reduce their hiding places and expose them to predators such as birds.

Use Natural Predators

Natural predators can also be used to control slaters on fennel plants. Ladybugs, ground beetles, and spiders are natural predators that feed on slaters. You can introduce these predators into your garden or plant flowers that attract them.

Apply Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of diatoms. It is an effective way to get rid of slaters on fennel plants. Sprinkle a thin layer of diatomaceous earth around the base of the plant. When slaters come in contact with the powder, it dehydrates them, causing them to die.

Use Insecticidal Soap

Insecticidal soap is a natural and effective way to control slaters on fennel plants. It works by breaking down the insect’s exoskeleton, causing it to dehydrate and die. Insecticidal soap can be purchased at most garden centers or can be made at home using liquid soap and water.

Create a Barrier

Creating a barrier around the fennel plant can also help to prevent slaters from infesting it. You can use copper tape or mesh to create a barrier around the base of the plant. Slaters do not like copper, so they will not cross the barrier.

Frequently Asked Questions (FAQ)

Are slaters harmful to fennel plants?

Yes, slaters can cause significant damage to fennel plants if left uncontrolled. They feed on the leaves and stems, causing damage to the plant.

Can I use chemical pesticides to control slaters on fennel plants?

Chemical pesticides are not recommended for controlling slaters on fennel plants as they can harm beneficial insects and pollinators.

Neem oil is not effective in controlling slaters on fennel plants.

How often should I apply insecticidal soap to control slaters on fennel plants?

Insecticidal soap should be applied every 7-10 days until the infestation is under control.

In conclusion, getting rid of slaters on fennel plants requires a combination of natural and mechanical control methods. Removing debris, using natural predators, applying diatomaceous earth, using insecticidal soap, creating a barrier, and maintaining good garden hygiene are all effective ways to control slaters on fennel plants. By following these methods, you can protect your fennel plants from slater infestations and ensure a healthy harvest.
