How to Get Rid of Slaters on Dianthus Plant

Updated: October 29, 2022

Dianthus plants are a popular choice for gardeners due to their beautiful, fragrant flowers and their ability to thrive in a variety of climates. However, one common problem that many gardeners face when growing dianthus plants is the presence of slaters. Slaters are small, grey, oval-shaped bugs that can cause damage to your dianthus plant. In this article, we will explore some effective ways to get rid of slaters on dianthus plants.

What are Slaters?

Slaters, also known as pill bugs or woodlice, are a type of crustacean that typically live in dark, damp areas such as under rocks or logs. They feed on decaying organic matter and are not harmful to humans. However, they can cause damage to plants by feeding on the foliage and roots.

Signs of Slaters on Dianthus Plants

The presence of slaters on dianthus plants can be identified by several signs. The most obvious sign is the appearance of small holes in the leaves of the plant. You may also notice wilting or yellowing leaves, which can be a result of slater damage to the roots. Additionally, you may see slaters crawling on the surface of the soil around the base of the plant.

How to Get Rid of Slaters on Dianthus Plants

  1. Remove debris and organic matter around the plant: Slaters thrive in damp, dark areas with lots of organic matter. By removing any debris or dead leaves from around the plant, you can reduce their habitat and make it less appealing for them to stick around.

  2. Water your plant correctly: Overwatering your dianthus plant can create an environment that is ideal for slaters. Make sure you water your plant only when necessary and avoid getting water on the foliage, which can attract slaters.

  3. Use diatomaceous earth: Diatomaceous earth is a natural powder made from the fossilized remains of diatoms. It works by absorbing the moisture from the bodies of slaters, causing them to dry out and die. Sprinkle a thin layer of diatomaceous earth around the base of your dianthus plant to create a barrier that will prevent slaters from crawling up.

  4. Use insecticidal soap: Insecticidal soap is a natural, non-toxic option for controlling slaters on dianthus plants. It works by suffocating the bugs and disrupting their cell membranes. Mix one tablespoon of insecticidal soap with one quart of water and spray it directly onto the foliage and soil around your plant.

  5. Use nematodes: Nematodes are microscopic worms that feed on slaters and other pests in the soil. They are a natural predator and can help control slater populations around your dianthus plant. You can purchase nematodes at your local garden center and apply them according to the package instructions.

FAQ

Can I use chemical pesticides to get rid of slaters?

Chemical pesticides should be used as a last resort, as they can harm beneficial insects and other organisms in your garden. Additionally, slaters have been known to develop resistance to chemical pesticides over time, making them less effective.

Are slaters harmful to humans?

Slaters are not harmful to humans and do not bite or sting. However, they can be a nuisance if they invade your home or garden.

How can I prevent slaters from coming back?

To prevent slaters from coming back, make sure you remove any debris or dead leaves from around your dianthus plant regularly. You can also try using companion planting techniques, such as planting herbs like lavender or thyme around your dianthus plant, as these plants have natural insect-repelling properties.
