Preventing and Treating Spider Mites on Flowering Houseplants

Why Spider Mites Target Gardenias, Plumeria, and Jasmine

Spider mites prefer flowering plants with tender foliage. They’re microscopic, hide on leaf undersides, and form visible webs only when populations explode.

Effective Treatment

1. Spray thoroughly with insecticidal soap, neem oil, or Hot Pepper Wax.
2. Cover 100% of leaf and stem surfaces—top, bottom, crevices.
3. Use gloved fingers to work solution into all areas.
4. Repeat in 5–7 days to catch hatchlings.
5. Weekly inspections catch early infestations ("dust" on leaf undersides).

Prevention

• Quarantine and spray new/outdoor plants before bringing inside.
• Provide optimal light and watering—healthy plants resist mites.
• Increase humidity (mites hate moisture).

Early detection and complete coverage are the keys to control.
