How to Get Rid of Slaters on Dahlia Plant

Dahlia plants are a popular choice for gardeners due to their vibrant colors and long blooming season. However, they can be susceptible to pests and one of the most common pests is the slater. Slater is a colloquial term used to describe woodlice or pillbugs that can infest your dahlia plants. They are not harmful to humans, but they can cause damage to your plants. In this article, we will discuss how to get rid of slaters on dahlia plants.

What are Slaters?

Slaters, also known as woodlice or pillbugs, are small crustaceans that are found in moist environments. They are usually gray or brown in color and have segmented bodies. They feed on decaying organic matter and can be found in gardens, under rocks, and in other damp areas.

Signs of Slaters Infestation

The first sign of a slater infestation is the presence of these bugs around your dahlia plants. They can be seen crawling over the leaves and stems of your plants. You may also notice damage to your plants, such as small holes in the leaves or chewed stems.

How to Get Rid of Slaters on Dahlia Plants

1. Remove Hiding Places

Slaters like to hide in damp areas such as under rocks, mulch, or debris. To get rid of them, remove any hiding places around your dahlia plants. This will make it more difficult for them to return.

2. Use Diatomaceous Earth

Diatomaceous earth is a natural insecticide that is safe for humans and pets but deadly for slaters. It works by dehydrating the slaters’ exoskeletons, which leads to their death. Sprinkle diatomaceous earth around the base of your dahlia plants and on the soil surface. Be sure to wear a mask and gloves when applying diatomaceous earth to avoid inhaling it.

3. Use Copper Tape

Copper tape is an effective way to repel slaters from your dahlia plants. Slaters are attracted to moist environments, and copper tape creates an electrical charge that repels them. Apply copper tape around the base of your dahlia plant or on the pot if it’s planted in one. This will create a barrier that slaters will not cross.

4. Use Beer Traps

Beer traps are an effective way to get rid of slaters. Slaters are attracted to the yeast in beer, so placing a shallow dish filled with beer near your dahlia plants will lure them in. Once they crawl into the dish, they will drown in the beer.

5. Use Insecticides

If all else fails, you can use insecticides to get rid of slaters on your dahlia plants. Look for insecticides that are labeled for use on slaters or woodlice. Be sure to follow the instructions on the label and avoid spraying directly on the plants.
