Pest identification
What's eating my pacifica vinca?
Aphids
Signs: Colonies on new shoots and flower buds cause curled leaves, distorted growth, and sticky honeydew; sooty mold follows.
Control: Knock off with a firm water jet; apply insecticidal soap or neem oil spray. Ladybirds and lacewings provide effective ongoing biological control.
Thrips
Signs: Silvery streaks or flecking on petals and leaves; flowers show brown edges and distorted petals; thrips rasp tissue and suck sap.
Control: Remove heavily infested blooms; spray with neem oil or spinosad on a 7-day cycle. Blue sticky traps help monitor and reduce adult numbers.
Whitefly
Signs: Clouds of tiny white insects fly up when plants are disturbed; leaves yellow and become coated in sticky honeydew.
Control: Use yellow sticky traps; spray leaf undersides with insecticidal soap or neem oil weekly. Ensure good air circulation between plants.
Spider mites
Signs: Pale stippling and fine webbing on leaves in hot, dry weather; leaves yellow and drop if unchecked.
Control: Rinse foliage; apply neem oil or insecticidal soap every 7 days for 3 weeks. Keeping soil consistently moist reduces mite pressure.

Pacifica Vinca pests — FAQ
What is eating my pacifica vinca?
Pacifica Vinca (Catharanthus roseus 'Pacifica') is a heat-tough bedding annual most commonly damaged by aphids and thrips. Whitefly and spider mites also strike in warm conditions. Outdoors, caterpillars occasionally chew the foliage. The naturally pest-resistant alkaloids in Catharanthus deter many insects, making pest pressure generally manageable with prompt spot treatment.
