Coleus plants are a beautiful addition to any garden, with their vibrant and colorful leaves. However, they are also prone to infestations from slaters, also known as pillbugs or woodlice. These small crustaceans feed on decaying plant matter and can cause serious damage to your coleus plants if left unchecked. In this article, we will discuss how to identify a slater infestation on your coleus plants and provide tips on how to get rid of them.

Identifying a Slater Infestation

The first step in getting rid of slaters on your coleus plants is to identify if you have an infestation. Look for the following signs:

  • Small gray or brown crustaceans crawling around the base of your coleus plants.
  • Damage to the leaves or stems of your coleus plants.
  • Leaves that have been eaten away, leaving only the veins.
  • Holes in the leaves of your coleus plants.

If you notice any of these signs, it is likely that you have a slater infestation.

Getting Rid of Slaters on Coleus Plants

Here are some tips on how to get rid of slaters on your coleus plants:

1. Remove Decaying Plant Matter

Slaters are attracted to decaying plant matter, so it’s essential to remove any dead leaves or stems from around your coleus plants. This will make the area less inviting for slaters and help prevent future infestations.

2. Use Diatomaceous Earth

Diatomaceous earth is a natural substance made from fossilized diatoms that can be effective in controlling slater populations. Sprinkle a thin layer of diatomaceous earth around the base of your coleus plant, making sure to cover the soil as well. The sharp edges of the diatomaceous earth will cut the slaters’ exoskeletons, causing them to dehydrate and die.

3. Use a Natural Insecticide

If you have a severe slater infestation, you may need to use a natural insecticide. Look for products that contain pyrethrins or neem oil, as these are effective in controlling slater populations. Be sure to follow the instructions on the label carefully.

4. Keep Your Garden Clean and Tidy

Slaters are attracted to cluttered and unkempt gardens, so it’s essential to keep your garden clean and tidy. Remove any debris, such as fallen leaves or dead plants, and keep the area around your coleus plants free of weeds.

5. Use Copper Tape

Copper tape is an effective way to prevent slaters from climbing up your coleus plants. Wrap copper tape around the base of your plant, making sure that it is touching the soil. The copper will create an electrical charge that repels slaters and prevents them from climbing up your plant.
