🧠 How to Identify White Bugs Correctly
Ask yourself:
- Do they fly when disturbed? → Likely whitefly
- Are they fluffy and cotton-like? → Mealybugs
- Are they clustered on new growth? → Aphids
- Are they in the soil and jumping? → Springtails
Correct identification is key to effective treatment.
🌿 Natural Control Methods
- Remove pests by hand where possible
- Wash plants with water to dislodge insects
- Encourage beneficial insects outdoors
- Improve airflow and reduce overcrowding
- Avoid overfeeding with nitrogen
Healthy plants are far less attractive to pests.
❌ Common Mistakes to Avoid
- Treating without identifying the pest
- Overusing chemical sprays
- Ignoring early signs
- Treating once instead of repeating
- Overwatering plants
Most treatments need repeating every 7–10 days.
