Slaters, also known as pillbugs or woodlice, are common pests that can infest dish garden plants. These small, armored insects feed on decaying organic matter and can damage the roots and leaves of your plants if left unchecked. Fortunately, there are several effective methods for getting rid of slaters and preventing them from returning.

Identify the Problem

The first step in getting rid of slaters is to confirm that they are indeed the problem. Slaters are small, gray or brown insects with segmented bodies and seven pairs of legs. They are commonly found in damp environments such as under plant pots or in the soil around the base of the plant. If you see these insects crawling around your dish garden, it’s time to take action.

Remove Attractants

Slaters are attracted to damp, decaying organic matter, so removing any such material from your dish garden can help deter them. This includes dead leaves, fallen flowers, and other debris that may be accumulating in the soil. Regularly pruning your plants and removing dead or dying foliage can also help keep slaters at bay.

Use Natural Predators

Another effective way to get rid of slaters is to introduce natural predators into your dish garden. Birds, lizards, and some types of beetles all prey on slaters and can help keep their population in check. You can also purchase nematodes, which are microscopic worms that feed on slaters and other soil-dwelling pests.

Apply Diatomaceous Earth

Diatomaceous earth is a natural substance made from fossilized diatoms that can be used to control slaters. It works by dehydrating the insects’ exoskeletons, leading to their death. To use diatomaceous earth, simply sprinkle a thin layer over the soil around your plants. Be sure to wear gloves and avoid inhaling the dust, as it can be irritating to the skin and lungs.

Use Insecticides

If natural methods are not effective, you may need to use an insecticide to control slaters. Look for products that are specifically formulated for use on dish garden plants and follow the instructions carefully. Be sure to keep children and pets away from treated areas, and wash your hands thoroughly after handling insecticides.

Prevent Future Infestations

Once you have successfully gotten rid of slaters, it’s important to take steps to prevent them from returning. This includes removing attractants such as decaying organic matter, regularly pruning your plants, and using natural predators or diatomaceous earth as needed. You can also try placing a barrier of crushed eggshells or copper wire around your dish garden, as slaters are known to avoid these materials.

By following these tips, you can effectively get rid of slaters on your dish garden plants and prevent future infestations.

FAQ

Are slaters harmful to my plants?

While slaters do feed on decaying organic matter, they can damage the roots and leaves of your plants if their population becomes too large.

Can I use household insecticides to control slaters?

Household insecticides may not be effective against slaters, as they are often formulated for use on flying insects such as mosquitoes or flies. Look for products that are specifically labeled for use on soil-dwelling pests such as slaters.

Will natural predators harm my plants?

Natural predators such as birds or lizards are unlikely to harm your plants, but be aware that some types of beetles may also feed on plant material. If in doubt, consult with a local gardening expert before introducing predators into your dish garden.
