How to Get Rid of Spider Mites in Gayfeather Plant

Updated: May 1, 2022

Gayfeather plants, also known as Liatris, are beautiful additions to any garden. However, they are susceptible to spider mites, which can quickly damage and kill the plant if left untreated. Spider mites are tiny pests that feed on the sap of the plant, leaving behind yellowed leaves and webbing. In this article, we will discuss how to identify spider mites and how to get rid of them in gayfeather plants.

Identifying Spider Mites

Spider mites are tiny pests that are difficult to see with the naked eye. They are usually less than 1mm in size and can be red, brown, or yellow. The first sign of spider mites is usually small yellow or white spots on the leaves of the gayfeather plant. As the infestation worsens, the leaves may turn yellow and fall off. You may also see small webs on the plant, which is a sign that spider mites are present.

Getting Rid of Spider Mites

If you suspect that your gayfeather plant has spider mites, it is important to take action quickly to prevent further damage. Here are some steps you can take to get rid of spider mites:

Step 1: Isolate the Infected Plant

The first step in getting rid of spider mites is to isolate the infected plant from other plants in your garden. This will prevent the infestation from spreading to other plants.

Step 2: Remove Infected Leaves

Next, remove any leaves that show signs of spider mite infestation. This will help prevent the infestation from spreading further.

Step 3: Spray with Water

Spraying the plant with water can help dislodge the spider mites and wash away their webs. Use a strong stream of water to thoroughly spray the leaves and stems of the plant.

Step 4: Apply Insecticidal Soap

Insecticidal soap is a safe and effective way to get rid of spider mites. Simply mix the soap with water according to the instructions on the label and spray the plant thoroughly. Be sure to cover both the tops and bottoms of the leaves.

Step 5: Use Neem Oil

Neem oil is another natural remedy for spider mites. Mix neem oil with water according to the instructions on the label and spray the plant thoroughly. Neem oil works by disrupting the feeding and reproduction of spider mites.

Prevention Tips

Preventing spider mites from infesting your gayfeather plants is much easier than treating them once they are already present. Here are some tips to help prevent spider mite infestations:

  • Keep your plants healthy by providing them with adequate water, sunlight, and nutrients.
  • Regularly inspect your plants for signs of pest infestations, including spider mites.
  • If you notice an infestation, take action quickly to prevent it from spreading.
  • Avoid over-fertilizing your plants, as this can make them more susceptible to pest infestations.


Can spider mites harm humans?

No, spider mites do not pose a threat to humans. However, they can cause significant damage to plants if left untreated.

Can I use chemical pesticides to get rid of spider mites?

Chemical pesticides can be effective in getting rid of spider mites, but they can also harm beneficial insects and pollinators. We recommend using natural remedies, such as insecticidal soap or neem oil, first.

How often should I inspect my plants for pest infestations?

We recommend inspecting your plants at least once a week for signs of pest infestations, especially during the growing season. Early detection is key to preventing the infestation from spreading.

In conclusion, spider mites can be a frustrating pest to deal with, but with these tips, you can get rid of them and prevent future infestations in your gayfeather plants. Remember to act quickly if you notice an infestation and take preventive measures to keep your plants healthy and pest-free.
