Spider Mites
Spider mites are tiny arachnids that suck plant sap, causing stippled, discolored leaves. They thrive in warm, dry conditions and can multiply rapidly.
Mogliche Ursachen
Low Humidity / Dry Air
Why: Spider mites prefer dry conditions and populations explode in low-humidity environments.
Signs to check: Problem is worst during winter with indoor heating, other plants nearby may also be affected.
Warm Indoor Temperatures
Why: Warm conditions speed up spider mite reproduction cycles, leading to rapid population growth.
Signs to check: Plant is in a warm room, mite damage progresses quickly over days to weeks.
Introduction from New Plants
Why: Spider mites can hitchhike on new plants brought into the home.
Signs to check: Problem started after adding a new plant, mites found on the newcomer as well.
Was prufen
- 1Look for fine webbing on leaf undersides and between stems
- 2Hold a white paper under a leaf and tap — look for tiny moving specks
- 3Check for stippled or speckled discoloration on leaf surfaces
- 4Inspect all nearby plants as mites spread easily
Was du tun kannst
- Isolate the affected plant immediately
- Spray the entire plant with a strong stream of water to dislodge mites
- Increase humidity around the plant — mites dislike moist conditions
- Apply insecticidal soap or neem oil, covering undersides of all leaves
- Repeat treatment every 5-7 days for at least 3-4 weeks to break the lifecycle
Wann Hilfe suchen
- Heavy webbing covering large portions of the plant
- Leaves are turning brown and falling off rapidly
- Mites have spread to multiple plants despite treatment
Wichtigste Erkenntnis
Spider mites are persistent but manageable. Increase humidity, treat consistently over several weeks, and inspect regularly to prevent reinfestations.
