How to Get Rid of Borers on Dew Plant

Updated: May 2, 2022

Dew plants, also known as drosera, are unique and fascinating carnivorous plants that are commonly grown in gardens and homes. These plants are known for their sticky leaves that trap and digest insects. Unfortunately, dew plants are also susceptible to borers, which can damage and kill the plant. Borers are small insects that bore into the stem of the plant and feed on the sap, causing the plant to weaken and eventually die. In this article, we will discuss different methods to get rid of borers on dew plants.

Identifying Borers on Dew Plants

Borers are tiny insects that can be difficult to spot, but there are a few signs to look out for. One of the most common signs of borer infestation is wilting leaves or stems that appear to be dying off. You might also notice small holes or tunnels in the stem of the plant. If you suspect your dew plant has borers, it’s essential to act quickly to prevent further damage.

Natural Methods for Getting Rid of Borers

There are several natural methods for getting rid of borers on dew plants. These methods are safe for both the plant and the environment.

1. Neem Oil

Neem oil is an excellent natural insecticide that can effectively kill borers. Mix one tablespoon of neem oil with a quart of water and spray it directly onto the affected areas of the plant. Repeat this process every two weeks until the borers have been eliminated.

2. Diatomaceous Earth

Diatomaceous earth is a natural powder made from fossilized diatoms that can be used as an insecticide. Sprinkle a thin layer of diatomaceous earth on the soil around the base of the plant. This will create a barrier that will prevent borers from crawling up into the plant.

3. Beneficial Nematodes

Beneficial nematodes are microscopic worms that can be used to control a variety of pests, including borers. Mix the nematodes with water and spray them directly onto the soil around the base of the plant. The nematodes will then burrow into the soil and attack any borers that try to feed on the plant.

Chemical Methods for Getting Rid of Borers

While natural methods are generally safer for the environment, sometimes chemical methods are necessary to get rid of borers on dew plants.

1. Insecticidal Soap

Insecticidal soap is a safe and effective way to kill borers without harming the plant. Mix one tablespoon of insecticidal soap with a quart of water and spray it directly onto the affected areas of the plant. Repeat this process every two weeks until the borers have been eliminated.

2. Systemic Insecticides

Systemic insecticides are chemicals that are absorbed by the plant and kill insects that feed on it. These types of insecticides are effective against borers but can be harmful to beneficial insects and pollinators. Use systemic insecticides only as a last resort and follow all safety precautions.

Preventing Borers on Dew Plants

Preventing borers on dew plants is much easier than getting rid of them once they’ve infested your plant. Here are some tips for preventing borers on dew plants:

  • Inspect your plants regularly: Check your dew plants for any signs of wilting or damage. Catching a borer infestation early can prevent further damage to your plant.
  • Keep your plants healthy: Healthy plants are less susceptible to pests and diseases. Make sure your dew plants receive proper sunlight, water, and nutrients.
  • Clean up debris: Remove any dead leaves or debris from around your plants. This will prevent pests from breeding in the area.
  • Plant companion plants: Companion plants such as marigolds and lavender can help repel pests from your garden.

However, by identifying the signs of infestation early and taking preventative measures, you can keep your plant healthy and thriving. Use natural methods whenever possible, and only resort to chemical methods as a last resort. With a little bit of care and attention, you can enjoy the unique beauty of your dew plant for years to come.
