How do I get rid of pests on my Staghorn Fern?

Staghorn Ferns can occasionally attract pests like mealybugs that hide in the nooks of the fronds. Finding them early is the key to keeping your plant healthy and pest free.

Check these first

  1. Inspect the base of the fronds where they meet the shield.
  2. Look for sticky residue on the leaves or the surface below the plant.
  3. Check nearby plants to see if the infestation has spread.

Likely causes

  1. Mealybugs

    Most likely

    How to tell: You will see small, white, cottony masses tucked into the base of the fronds. The plant might also look sticky or show stunted growth.

    What to do: Dip a cotton swab in rubbing alcohol and touch it directly to the pests to kill them on contact. For larger infestations, spray the plant with a mild insecticidal soap.

  2. Scale Insects

    Possible

    How to tell: These look like small, brown, hard bumps on the undersides of the fronds. They do not move and can be mistaken for part of the plant.

    What to do: Gently scrape the bumps off with your fingernail or a soft brush. Follow up by wiping the fronds with a cloth soaked in diluted neem oil.

Stopping it coming back

Questions people ask

Can I use heavy pesticides?
Avoid harsh chemicals, as Staghorn Ferns are sensitive. Stick to gentle options like insecticidal soap or rubbing alcohol.
Will the pests kill my plant?
If left untreated for a long time, pests can drain the plant of nutrients and cause it to decline. Catching them early prevents this.
