- Look for tiny white specks moving slowly on the foliage.
Likely causes
Mealybugs
Most likelyHow to tell: Look for small, white, cottony masses tucked into the leaf axils or along the base of the leaves. You might also see a sticky residue called honeydew on the foliage.
What to do: Dab the bugs with a cotton swab dipped in rubbing alcohol to kill them on contact. For a larger infestation, spray the entire plant with insecticidal soap every 7 days until they are gone.
Scale insects
PossibleHow to tell: This is less common for this plant, and usually happens if the plant is stressed by low light. Look for small, hard, brown bumps that look like tiny shells on the leaves.
What to do: Gently scrape the bumps off with your fingernail or a soft brush. Wipe the leaves down with a cloth soaked in diluted neem oil to prevent them from returning.

When to worry
If the plant is covered in sticky honeydew or leaves are starting to yellow and curl, take action immediately. A few isolated bugs are easy to manage, but a full infestation can weaken the plant quickly.
Stopping it coming back
Keep your pineapple in bright, direct sun to keep it strong and resistant to pests. Regularly wipe the leaves with a damp cloth to remove dust and check for early signs of intruders.
