Maple Trunk Holes: Sapsucker Damage with Merit Insecticide Deterrent

Observation

One of 13 2-year-old maples: water running down trunk, small holes. Others unaffected.

Diagnosis: Woodpecker/Sapsucker Holes

• Maples = thin bark → easy sap flow from minor damage
• Two scenarios:
• Bird after insect in bark
• Sapsucker drills holes → sap flows → insects feed → bird eats insects

Treatment: Merit (Imidacloprid) Spray

• Spray hole areas on bark
• Systemic absorption into bark/wood
• Kills insects in bark
• Prevents insect attraction to sap
• Bird leaves when food source gone

Why This Works

Targets the insect-bird food chain rather than bird directly. Merit's systemic action protects wound area during healing. Thin-barked maples especially vulnerable to sap loss from repeated wounding.
