Updated: July 9, 2023

Phlox plants are a popular choice for gardeners due to their vibrant colors and beautiful blooms. However, these plants can sometimes be plagued by an annoying pest called lerps. Lerps are small, scale-like insects that attach themselves to the leaves of phlox plants and suck out the sap, causing damage to the plant. If left untreated, lerps can weaken the plant and make it more susceptible to other diseases and pests. In this article, we will discuss some effective methods to get rid of lerps and keep your phlox plants healthy.

Identifying Lerps

Before we dive into the methods of getting rid of lerps, it’s important to know how to identify them. Lerps are small, oval-shaped insects that resemble scales or miniature seashells. They usually have a white or grayish color and can be found attached to the undersides of the leaves of phlox plants. Upon closer inspection, you may notice a sticky substance on the leaves, which is a telltale sign of lerp infestation.

Natural Methods

If you prefer to use natural methods to get rid of lerps on your phlox plants, there are a few options available:

1. Manual Removal

The simplest method of getting rid of lerps is by manually removing them from the affected leaves. You can use a soft brush or your fingers to gently scrape off the lerps from the leaves. Be sure to dispose of them properly to prevent reinfestation.

2. Neem Oil

Neem oil is a natural insecticide that can effectively control lerps on phlox plants. Mix neem oil with water according to the instructions on the bottle and spray it onto the affected leaves. The oil will suffocate the lerps and prevent them from further damaging your plants.

3. Insecticidal Soap

Insecticidal soap is another effective natural remedy for lerps. It works by breaking down the outer protective layer of the insects, leading to their demise. Dilute insecticidal soap with water and spray it onto the affected leaves. Repeat this process every few days until the infestation is under control.

Chemical Methods

If natural methods fail to eliminate the lerp infestation on your phlox plants, you may need to resort to chemical methods. 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 impacts on the environment. Always follow the instructions on the pesticide label and wear protective clothing when applying chemicals.

1. Systemic Insecticides

Systemic insecticides are absorbed by the plant and can control lerps from within. These insecticides are applied to the soil around the base of the phlox plant, and they are taken up by the roots. As the plant circulates sap, the systemic insecticide is distributed throughout the entire plant, killing lerps and other pests that feed on it.

2. Contact Insecticides

Contact insecticides are sprayed directly onto the affected leaves, killing lerps on contact. These insecticides typically contain chemicals such as pyrethroids or organophosphates. It’s important to choose a pesticide that is labeled for use on phlox plants and follow the recommended application rates.

Prevention Tips

Prevention is always better than cure when it comes to lerp infestations. Here are some tips to help prevent lerps from attacking your phlox plants:

  1. Regularly inspect your plants: Regularly inspecting your phlox plants can help you detect any signs of lerp infestation early on. Look for lerps on the undersides of leaves and check for sticky substances or wilting leaves.

  2. Maintain good plant health: Healthy plants are less likely to be affected by pests and diseases. Ensure that your phlox plants are well-watered, properly fertilized, and receive adequate sunlight.

  3. Promote biodiversity: Encouraging biodiversity in your garden can help control lerps naturally. Planting a variety of flowers and herbs can attract beneficial insects such as ladybugs and lacewings, which prey on lerps and other pests.

  4. Prune affected leaves: If you notice lerp-infested leaves on your phlox plants, promptly prune them off to prevent the infestation from spreading.

Conclusion

Lerps can be a nuisance for phlox plant owners, but with the right methods and preventive measures, you can effectively control and eliminate these pests. Whether you choose natural or chemical methods, it’s important to remain vigilant and take action at the first sign of infestation. By following the tips outlined in this article, you can keep your phlox plants healthy and beautiful year-round.
