Sticky Droplets on Nepenthes After Hail Damage: Pest Check and Sap Exudation

An Omaha grower's Nepenthes 'Poi Dog' was devastated by hail, losing all but two leaves. After moving indoors to a SE corner with afternoon sun, new growth appears but sticky droplets cover stems and leaves. Asks if this indicates pests (aphids were on yard vines).

Initial Inspection

Photo shows no visible pests. Check with hand lens for:

• Whitish scale at leaf joints (scale insects)
• Tiny, elongated insects (thrips)

These are the most common Nepenthes pests. If found, treat with recommended insecticides (see video podcast).

Follow-Up: Beneficial Insects and Sap

Grower found a jumping spider and fungus gnats in soil—neither harms the plant. The sticky droplets are likely nectar/sap from earlier hail damage; damaged tissue often exudes fluid during repair. First new pitcher may be deformed from the trauma.

Action

Monitor. Precautionary insecticide spray (using recommended products) won't harm the plant. Video on insecticides: YouTube link
