Freesia is a beautiful and fragrant plant that is commonly grown in gardens and pots. However, like all plants, it is susceptible to pests and diseases. One of the most common pests that can infest freesia plants is slaters. Slaters are small, gray, pill-shaped bugs that are also known as woodlice or sowbugs. They feed on decaying plant matter and can cause damage to the leaves and stems of freesia plants. In this article, we will discuss how to get rid of slaters on freesia plants.

Identify the Problem

Before you can get rid of slaters on your freesia plant, you need to make sure that they are indeed the problem. Slaters can be easily identified by their gray color and pill-like shape. They are usually found in damp areas of the garden or pot, such as under rocks or in decaying plant matter. Look for signs of damage on the leaves and stems of your freesia plant. If you see irregular holes or notches in the leaves, it could be a sign of slater damage.

Remove Decaying Plant Matter

Slaters feed on decaying plant matter, so one way to get rid of them is to remove any dead leaves, flowers or other plant debris from around the freesia plant. This will reduce the food source for slaters and make your plant less attractive to them. Use a pair of scissors or gardening shears to trim away any dead or dying leaves from your freesia plant.

Create a Dry Environment

Slaters prefer damp environments, so another way to get rid of them is to create a dry environment around your freesia plant. Make sure that the soil around your plant is well-drained and not overly wet. Water your plant only when the soil feels dry to the touch. If you have a pot-bound freesia plant, make sure that the pot has adequate drainage holes to allow excess water to drain away.

Use Natural Pest Control

If you want to get rid of slaters on your freesia plant without using chemicals, there are several natural pest control methods that you can try. Sprinkle diatomaceous earth around your plant to create a barrier that slaters cannot cross. Diatomaceous earth is made from fossilized algae and is safe for pets and humans to use. You can also try placing a shallow dish of beer near your plant. Slaters are attracted to the yeast in beer and will crawl into the dish and drown.

Use Chemical Pest Control

If natural pest control methods are not effective in getting rid of slaters on your freesia plant, you may need to use chemical pest control methods. There are several insecticides that are effective against slaters, such as carbaryl or pyrethrin-based products. Follow the instructions on the product label carefully and apply the insecticide according to the recommended dosage.


Slaters can be a nuisance for freesia plant growers, but with proper care and attention, they can be effectively controlled. By removing decaying plant matter, creating a dry environment, using natural pest control methods or chemical pest control methods, you can get rid of slaters on your freesia plant and keep it healthy and beautiful.


Are slaters harmful to humans?

No, slaters are not harmful to humans. They do not bite or sting and are generally considered harmless.

Can slaters infest other plants besides freesia?

Yes, slaters can infest other plants besides freesia. They feed on decaying plant matter, so any plant with dead or dying leaves or debris is susceptible to infestation.

How often should I water my freesia plant?
