The heartleaf ice plant (Mesembryanthemum crystallinum) is a popular succulent plant that is known for its stunning, shimmering leaves. However, one common problem that can plague this plant is the presence of slaters. Slaters, also known as sowbugs or woodlice, are small crustaceans that are often found in damp environments, such as potted plants. While they do not cause significant damage to the heartleaf ice plant, their presence can be unsightly and unwanted. In this article, we will discuss effective methods to get rid of slaters on heartleaf ice plants.

Identify the Problem

Before taking any action, it is important to confirm that your heartleaf ice plant is indeed infested with slaters. Slaters are small, grayish-brown creatures that resemble tiny armadillos. They have segmented bodies and multiple sets of legs. You may notice them crawling around the base or underneath the leaves of your heartleaf ice plant.

Remove Excess Moisture

Slaters thrive in damp environments, so it is crucial to eliminate excess moisture around your heartleaf ice plant. Avoid overwatering the plant and ensure proper drainage by using well-draining soil and a pot with drainage holes. Additionally, make sure to remove any standing water or wet debris from the plant’s surroundings.

Organic Control Methods

If you prefer to use organic methods to get rid of slaters on your heartleaf ice plant, there are several options available:

1. Diatomaceous Earth

Diatomaceous earth is a natural substance made from the fossilized remains of diatoms. It is highly effective in controlling slaters as it damages their exoskeletons, leading to dehydration and death. Sprinkle a thin layer of food-grade diatomaceous earth around the base of your heartleaf ice plant, focusing on areas where slaters are most active. Reapply after rain or watering.

2. Coffee Grounds

Coffee grounds have been found to repel slaters due to their high acidity. Simply sprinkle used coffee grounds around the plant’s base to deter slaters from approaching. This method is not only effective but also provides additional nutrients to the soil.

3. Copper Tape

Slaters are known to avoid copper surfaces as it gives them a slight electric shock. Attach a strip of copper tape around the pot or container of your heartleaf ice plant to create a barrier that slaters will not cross.

Chemical Control Methods

If organic methods do not provide satisfactory results, you may consider using chemical control methods. It is important to note that these methods should be used as a last resort and with caution:

1. Insecticides

There are various insecticides available on the market that are specifically designed to control slaters and other pests. Look for products that contain active ingredients such as pyrethroids or carbaryl. Follow the instructions provided by the manufacturer and apply the insecticide according to the recommended dosage and frequency.

2. Bait Traps

Bait traps can be an effective way to control slaters without using harsh chemicals. Place commercially available bait traps near the heartleaf ice plant, focusing on areas where slaters are most active. These traps contain an attractant that lures slaters in and kills them.

Prevention Tips

Prevention is always better than cure when it comes to pest control. Here are some preventive measures you can take to minimize the chances of slater infestations on your heartleaf ice plant:

  • Regularly inspect your plants for any signs of pests, including slaters.
  • Keep your heartleaf ice plant clean by removing fallen leaves and debris.
  • Avoid overwatering and ensure proper drainage to eliminate excess moisture.
  • Increase air circulation around the plant by spacing out multiple plants or using a fan.
  • Avoid using excessive amounts of organic matter, such as mulch or compost, which can attract slaters.

By following these prevention tips and implementing the appropriate control methods, you can effectively get rid of slaters on your heartleaf ice plant. Remember to choose the method that aligns with your preferences and always prioritize the health and well-being of your plants.
