Coffee Plant Mealybugs: Systemic Insecticide Best for Outdoor Hedge

Your 6-7 foot coffee hedge has mealybugs (white powdery, orange crawlers when rubbed) protected by ants. Two approaches:

Option 1: Alcohol-Soap Spray (For Indoor/Accessible)

• 50% water / 50% rubbing alcohol + 1 tsp dish soap per liter
• Twice weekly for 2 MONTHS
• Kills crawlers and adults on contact
• Must continue for full hatch cycles

Option 2: Systemic Insecticide (BEST for Hedge)

• Bayer Advanced 12-Month Tree & Shrub Protect & Feed
• Mix per label, water into soil around hedge
• Systemic uptake → kills mealybugs + prevents return for 12 MONTHS
• Also fertilizes
• Walmart, Lowe's, garden centers, or online

Ant Connection

Ants "farm" mealybugs for honeydew. Systemic kills mealybugs → ants leave. Spray alone won't break this cycle effectively on a large hedge.

If Bayer Unavailable

Local garden center: "My hedge has mealybugs" → they'll recommend effective local product + application method.

The systemic is worth finding—it solves the problem completely with one application.
