Ferns are a common houseplant and garden favorite, but they are not immune to pests. One of the most damaging pests that affect fern plants is borers. These tiny insects can cause severe damage to fern plants by tunneling into the stems and leaves, causing wilt, stunted growth, and even death. Fortunately, there are several ways to get rid of borers on fern plants.

Identify the Borer

The first step in getting rid of borers is to identify them correctly. Borers are usually small, slender insects that have long antennae and wings. They lay their eggs on the surface of the fern plant, and when the eggs hatch, the larvae bore into the plant’s tissue. You can identify borers by looking for small holes in the plant’s stem or leaves, sawdust-like debris at the base of the plant, or yellowing or wilting leaves.

Natural Remedies

One way to get rid of borers on fern plants is to use natural remedies. Here are some natural remedies you can use:

Neem Oil

Neem oil is a natural insecticide that is effective in getting rid of borers. Mix neem oil with water and spray it on the fern plant’s leaves and stems.

Garlic

Garlic is another natural remedy that can help get rid of borers. Crush some garlic cloves and mix them with water. Spray this mixture on the fern plant.

Diatomaceous Earth

Diatomaceous earth is a natural powder made from fossilized diatoms. Sprinkle a thin layer of diatomaceous earth around the base of the fern plant. The powder will stick to the borers’ bodies, causing them to dehydrate and die.

Chemical Treatments

If natural remedies do not work, you may need to use chemical treatments to get rid of borers on fern plants. Here are some chemical treatments you can use:

Insecticides

Insecticides such as carbaryl or malathion are effective in getting rid of borers. Mix the insecticide according to the manufacturer’s instructions and spray it on the fern plant’s leaves and stems.

Systemic Insecticides

Systemic insecticides are absorbed by the fern plant and transported throughout the plant’s tissue. This means that when the borers feed on the plant, they ingest the insecticide and die. Apply systemic insecticide to the soil around the fern plant.

Prevention

Preventing borers from attacking your fern plants is better than trying to get rid of them. Here are some preventative measures you can take:

Keep Your Fern Plant Healthy

A healthy fern plant is less likely to be attacked by borers. Make sure your fern plant is getting enough water, light, and nutrients.

Monitor Your Fern Plant

Regularly inspect your fern plant for signs of borers. If you notice any holes or sawdust-like debris, take action immediately.
