If you have a licorice plant in your garden, you may have noticed small, greyish-brown insects crawling around the leaves and stems. These insects are called slaters, also known as woodlice or pill bugs. While slaters are generally harmless to licorice plants, they can become a nuisance if their population grows out of control. In this article, we will discuss effective ways to get rid of slaters on licorice plants.

Understanding Slaters

Before we dive into the methods of eliminating slaters, it is essential to understand these insects and their behavior. Slaters are not actually insects but rather crustaceans that have adapted to living on land. They are often found in damp and dark areas, such as under rocks, logs, or piles of decaying organic matter.

Slaters feed on decaying plant material and are considered beneficial in compost piles as they aid in decomposition. However, when their population explodes and they start feeding on healthy plants like licorice, it becomes necessary to take action.

1. Remove Attractants

The first step in controlling slaters on your licorice plant is to eliminate any attractants that may be drawing them to your garden. Slaters are attracted to damp environments with plenty of organic matter. Therefore, removing any debris, fallen leaves, or decaying plants near your licorice plant can help deter these pests.

2. Improve Drainage

Slaters thrive in moist conditions, so improving drainage around your licorice plant can make the environment less favorable for them. Ensure that the soil is well-drained and not overly saturated. Consider adding organic matter or sand to improve the soil’s drainage capacity.

3. Create a Barrier

Creating a physical barrier around your licorice plant can help prevent slaters from reaching the plant. You can use materials like copper tape, diatomaceous earth, or petroleum jelly to create a barrier that slaters are unlikely to cross. Apply the chosen material around the base of the plant or on the rims of pots if your licorice plant is in a container.

4. Natural Predators

Introducing natural predators into your garden can be an effective way to control slater populations. Certain animals, such as birds, frogs, and toads, feed on slaters and can help keep their numbers in check. Consider attracting these predators to your garden by providing suitable habitats or installing bird feeders.

5. Organic Insecticides

If the above methods do not provide adequate control, you can resort to organic insecticides to eliminate slaters on your licorice plant. One effective option is a product containing spinosad, which is derived from a naturally occurring soil bacterium. Follow the instructions on the label carefully when applying any insecticide and avoid using it excessively.

6. Traps

Trapping slaters can also be an effective method to reduce their population on licorice plants. You can create homemade traps using materials such as rolled-up newspaper or empty tuna cans filled with dampened soil or vegetable scraps. Place these traps near your licorice plant, and the slaters will be attracted to them. Check the traps regularly and dispose of captured slaters away from your garden.

7. Handpicking

While it may not be feasible for large infestations, handpicking slaters off your licorice plant can be an effective control method for smaller populations. Wear gloves and manually remove the pests from the leaves and stems of your plant. Drop them into a bucket of soapy water to prevent them from returning to your garden.

8. Regular Maintenance

Regularly inspecting your licorice plant for signs of slaters and taking prompt action when you spot them is crucial for effective control. Regular maintenance, such as removing dead leaves, keeping the area clean, and providing proper watering, will also help create an environment less favorable for slaters to thrive.

Conclusion

While slaters may not pose a significant threat to licorice plants, their presence can be bothersome. By following these eight methods, you can effectively control slater populations on your licorice plant and maintain its health and beauty. Remember, prevention and early intervention are key to preventing any pest infestations in your garden.
