Mealybugs
Mealybugs are soft-bodied, sap-sucking insects covered in a white, waxy coating. They cluster in leaf joints, on stems, and under leaves.
Posibles Causas
Introduction from Infested Plants
Why: Mealybugs commonly arrive on new plants purchased from nurseries or received from others.
Signs to check: White cottony masses appeared after introducing a new plant.
Warm Indoor Conditions
Why: Indoor warmth and lack of natural predators allow mealybug populations to grow unchecked.
Signs to check: Population grows steadily, no natural predators present indoors.
Overfeeding with Nitrogen
Why: Excess nitrogen produces soft, lush growth that is more attractive and vulnerable to mealybugs.
Signs to check: Plant has very lush, soft foliage, mealybugs concentrate on new growth.
Que Verificar
- 1Look for white, cottony clusters at leaf joints and stem bases
- 2Check leaf undersides and where leaves meet stems
- 3Look for sticky honeydew residue on and below the plant
- 4Inspect nearby plants for signs of spread
Que Puedes Hacer
- Isolate the plant from others immediately
- Dab individual mealybugs with a cotton swab dipped in 70% rubbing alcohol
- Spray the entire plant with insecticidal soap, focusing on crevices
- For heavy infestations, apply neem oil solution every 7-10 days
- Repeat treatments for at least 3-4 weeks, as eggs may survive initial applications
Cuando Buscar Ayuda
- Mealybugs are found on roots (root mealybugs require soil drench treatment)
- Plant is severely weakened with significant leaf drop
- Infestation keeps returning despite repeated treatments
Punto Clave
Mealybug treatment requires patience and persistence. Treat all crevices thoroughly and repeat applications to catch newly hatched nymphs.
