- Check the undersides of stems for small brown bumps.
- Look for sticky residue on the leaves or the surface below the plant.
Likely causes
Mealybugs
Most likelyHow to tell: You will see small white cottony masses tucked into the stem joints. They suck the sap and leave behind a sticky residue.
What to do: Dip a cotton swab in rubbing alcohol and dab it directly onto each bug to kill them instantly. Repeat this process every 3 to 5 days until you see no more signs of insects.
Scale insects
PossibleHow to tell: These look like small brown or tan bumps that do not move. They attach firmly to the stem surface.
What to do: Gently scrape them off with your fingernail or a soft brush. Wipe the stems down with a mild soap and water solution once a week for a month.

When to worry
If the infestation covers more than half the plant, it is very difficult to save. A few bugs are manageable if you catch them early.
Stopping it coming back
Wipe your plant down with a damp cloth every month to remove dust and discourage pests. Keep new plants away from your collection for 2 weeks to ensure they are bug free.

Questions people ask

- Yes, neem oil is effective, but be careful to apply it in the evening to avoid burning the stems in direct sun. Spray it lightly over the entire plant.
- Will these bugs spread to my other plants?
- Yes, mealybugs move easily from plant to plant. Isolate your Mistletoe cactus immediately until it is completely clear.
