Common Pests Affecting Old Man Cactus

  • Mealybugs
  • Scale Insects

  • Fungus Gnats

Mealybugs

Mealybugs appear as small, cotton-like clusters on the cactus surface. They feed on plant sap, weakening the cactus and causing deformities.

Troubleshooting Steps:

  • Isolate the affected plant to prevent spreading.
  • Use a cotton swab dipped in alcohol to remove visible bugs.
  • Apply insecticidal soap or neem oil to the affected areas.
  • Repeat treatment weekly until pests are eradicated.

Scale Insects

Scale insects look like small, rounded bumps on the cactus surface. They feed on sap and can cause yellowing or wilting.

Troubleshooting Steps:

  • Manually remove scales with a soft brush or cloth.
  • Apply horticultural oil or neem oil to suffocate the pests.
  • Ensure thorough coverage of all affected areas.
  • Repeat treatment as needed every 7-10 days.

Spider Mites

Spider mites are tiny, often red or yellow, and create fine webbing on the cactus. They suck plant juices, leading to stippling or discoloration.

Troubleshooting Steps:

  • Increase humidity around the plant if possible.
  • Wash the plant with a strong stream of water to dislodge mites.
  • Use miticide or insecticidal soap to treat infestations.
  • Repeat every 7 days until mites are gone.
