Prevention and Control Methods

Updated: May 8, 2023

Boston ferns are a popular choice for indoor and outdoor plants. They are known for their lush green foliage, which adds a natural touch to any space. However, like any other plant, Boston ferns are susceptible to pests that can damage the plant’s health and appearance. In this article, we will discuss the most common Boston fern plant pests, how to prevent them, and control methods to keep your ferns healthy and thriving.

Common Boston Fern Plant Pests

1. Mealybugs

Mealybugs are small, white insects that suck sap from the fern’s leaves and stems. They are usually found in clusters on the underside of the leaves and in the crevices of the plant. Mealybugs secrete a sticky substance called honeydew, which attracts ants and can cause fungal growth.

2. Scale Insects

Scale insects are tiny, oval-shaped pests that attach themselves to the fern’s leaves and stems. They feed on the plant’s sap and can cause yellowing of the leaves, stunted growth, and leaf drop. Scale insects secrete a waxy substance that protects them from predators.

3. Spider Mites

Spider mites are tiny pests that spin webs on the fern’s leaves and stems. They feed on the plant’s sap and can cause yellowing of the leaves, webbing, and leaf drop. Spider mites thrive in hot, dry conditions and can reproduce quickly.

4. Thrips

Thrips are small, slender insects that feed on the plant’s sap by piercing the leaves and sucking out the contents. They cause damage by creating tiny scars on the leaves, which can lead to discoloration and distortion.

Prevention Methods

Preventing pests from infesting your Boston ferns is crucial to keeping them healthy. Here are some simple prevention methods you can follow:

  • Inspect new plants: Always inspect new plants before bringing them home. Check for signs of pests or diseases.
  • Quarantine new plants: Keep new plants away from existing ones for a few weeks to ensure they are pest-free.
  • Clean surroundings: Keep the area around your ferns clean and free from debris.
  • Proper watering: Water your ferns correctly by avoiding overwatering or underwatering.
  • Proper lighting: Ensure your ferns receive adequate light but not direct sunlight.
  • Humidity levels: Maintain humidity levels between 50-60% by misting your ferns regularly or using a humidifier.
  • Good air circulation: Provide good air circulation by placing your ferns in an area with proper ventilation.

Control Methods

If you notice signs of pest infestation on your Boston ferns, it is essential to take immediate action. Here are some control methods you can use:

1. Manual Removal

Manual removal involves physically removing pests from your ferns using a soft-bristled brush or cotton swab dipped in rubbing alcohol. This method is effective for removing mealybugs and scale insects.

2. Neem Oil

Neem oil is a natural pesticide derived from neem trees. It works by disrupting the insect’s life cycle, preventing them from reproducing. Dilute neem oil with water according to the manufacturer’s instructions and spray it onto your ferns.

3. Insecticidal Soap

Insecticidal soap is a safe and effective pesticide made from natural ingredients like potassium salts of fatty acids. It works by suffocating pests like spider mites and thrips by covering their breathing holes. Dilute insecticidal soap with water according to the manufacturer’s instructions and spray it onto your ferns.
