Slaters, also known as woodlice or pillbugs, are small crustaceans that can be found in gardens and indoor plants. While they are generally harmless to humans, they can become a nuisance when they infest your sword plant. Slaters feed on decaying plant matter and can damage the leaves and roots of your sword plant if their population grows too large. If you’re dealing with slaters on your sword plant, here are some effective methods to get rid of them.

1. Identify the Problem

Before you start treating the slater infestation, it’s important to make sure that you’re dealing with slaters and not another pest. Slaters are gray or brownish in color, have segmented bodies, and move in a characteristic sideways motion. They are usually found in damp areas and tend to hide under pots or in crevices.

2. Remove Decaying Plant Matter

Slaters are attracted to decaying plant matter, so removing any dead leaves or debris from around your sword plant is essential. This will eliminate their food source and discourage them from staying in the area. Regularly clean the soil surface and remove any fallen leaves or rotting plant material.

3. Improve Drainage

Slaters thrive in moist environments, so improving drainage around your sword plant can help deter them. Ensure that your pot has adequate drainage holes and use a well-draining potting mix. Avoid overwatering your plant, as excess moisture can create the perfect breeding ground for slaters.

4. Natural Predators

Introducing natural predators of slaters can be an effective method of control. Birds, frogs, lizards, and predatory insects such as ground beetles or centipedes feed on slaters and can help keep their population in check. Consider attracting these beneficial creatures to your garden by providing birdhouses, water sources, or suitable habitats.

5. Diatomaceous Earth

Diatomaceous earth is a natural and non-toxic substance that can be used to control slaters. It is composed of the fossilized remains of diatoms, which are microscopic algae with sharp edges. Sprinkle a thin layer of diatomaceous earth around the base of your sword plant. When slaters crawl over it, the sharp particles will pierce their exoskeletons, causing them to dehydrate and die.

6. Beer Traps

Beer traps are a popular method for controlling slaters and other pests. Fill a shallow container, such as a small saucer or dish, with beer and place it near your sword plant. Slaters are attracted to the scent of beer and will crawl into the container. Once inside, they will drown in the liquid. Empty and refill the beer traps regularly to maintain their effectiveness.

7. Organic Insecticides

If the infestation is severe and other methods haven’t been successful, you may need to resort to organic insecticides. There are several options available that are safe for use on edible plants. Look for products containing ingredients such as pyrethrin or neem oil, which are effective against slaters and other garden pests. Follow the instructions carefully when applying these insecticides to avoid harming beneficial insects or your sword plant.

8. Prevent Reinfestation

After successfully getting rid of slaters on your sword plant, it’s important to take steps to prevent reinfestation. Regularly inspect your plant for signs of decay or excess moisture and address these issues promptly. Avoid overwatering and ensure proper drainage in your potting mix. Keep the area around your plant clean and free from decaying plant matter.

In conclusion, slaters can be a nuisance when they infest your sword plant, but there are effective methods to get rid of them. Start by identifying the problem and removing decaying plant matter. Improve drainage, introduce natural predators, and use diatomaceous earth or beer traps as organic control methods. If necessary, resort to organic insecticides. Lastly, take preventive measures to avoid future infestations. With these steps, you can effectively eliminate slaters and protect your sword plant.
