Jacobs Ladder (Polemonium caeruleum) is a beautiful flowering plant that adds charm and color to any garden. However, like many other plants, it can fall victim to pests such as slaters. Slaters, also known as woodlice or pill bugs, are small crustaceans that feed on decaying organic matter and can cause damage to plants if their population becomes too large.

If you’ve noticed slaters on your Jacobs Ladder plant, it’s important to take action to prevent further damage. In this article, we will discuss several effective methods to get rid of slaters and protect your plant.

Identify the Problem

Before taking any action, it’s essential to confirm that the pests you’re dealing with are indeed slaters. Slaters are small, oval-shaped creatures with a segmented body and seven pairs of legs. They are typically gray or brown in color and have a hard exoskeleton.

Inspect your Jacobs Ladder plant closely for the presence of slaters. Look under leaves, in crevices, and around the base of the plant. If you find these pests, it’s time to take action.

Natural Solutions

  1. Remove debris: Slaters are attracted to decaying organic matter, so clearing away any fallen leaves or dead plant material around your Jacobs Ladder can help reduce their population. Regularly clean up the area around the plant and dispose of the debris in sealed bags or compost bins.

  2. Adjust watering practices: Slaters thrive in moist environments. To discourage their presence, avoid overwatering your Jacobs Ladder plant. Allow the soil to dry out slightly between waterings.

  3. Introduce natural predators: Some insects, such as ground beetles and centipedes, feed on slaters. Introducing these predators into your garden can help control the slater population naturally. You can attract these beneficial insects by planting diverse, native plants that provide them with food and shelter.

  4. Use diatomaceous earth: Diatomaceous earth is a natural powder made from fossilized algae. It works by dehydrating and damaging the exoskeleton of slaters, eventually leading to their demise. Sprinkle a thin layer of diatomaceous earth around the base of your Jacobs Ladder plant to create a barrier that will discourage slaters from approaching.

Chemical Solutions

If the natural methods mentioned above fail to control the slater population on your Jacobs Ladder plant, you may need to resort to chemical solutions. It’s important to note that chemical pesticides should be used as a last resort and with caution, as they can harm beneficial insects and have negative effects on the environment. Always read and follow the instructions provided by the manufacturer before applying any chemicals.

  1. Insecticidal soap: Insecticidal soap is a low-toxicity option that can effectively eliminate slaters. Spray a diluted solution of insecticidal soap onto the affected areas of your Jacobs Ladder plant, paying close attention to the undersides of leaves where slaters often hide. Repeat the application as necessary until the slaters are gone.

  2. Pyrethrin-based insecticides: Pyrethrin-based insecticides are derived from chrysanthemum flowers and are considered relatively safe for use in gardens. These insecticides target a wide range of pests, including slaters. Follow the instructions on the product label and apply as directed.

  3. Chemical bait traps: Chemical bait traps can be an effective way to lure and kill slaters. These traps contain a poisonous substance that attracts slaters, causing them to ingest it and subsequently die. Place these traps near your Jacobs Ladder plant, following the instructions provided by the manufacturer.

Preventing Future Infestations

Once you’ve successfully eliminated the slaters from your Jacobs Ladder plant, it’s important to take preventative measures to avoid future infestations. Here are a few tips to help keep your plant healthy and pest-free:

  • Regularly inspect your Jacobs Ladder for signs of pests.
  • Practice good garden hygiene by removing fallen leaves and debris promptly.
  • Avoid overwatering, as moist conditions attract slaters.
  • Encourage beneficial insects by planting a diverse range of native plants in your garden.
  • Monitor other plants in your garden for signs of slaters and take prompt action if necessary.

By following these steps, you can effectively get rid of slaters on your Jacobs Ladder plant and prevent them from causing further damage. Remember, it’s important to be patient and persistent when dealing with pests, as it may take some time to fully eradicate them.
