Leech Control in a Large Private Pond

Leeches in a 33-acre camp pond are tough to eliminate. Chemicals are prohibitively expensive and risky for swimmers.

Best: Consult a fish veterinarian (e.g., Dr. Eric Johnson in US, or Stijn Verbinnen/Maarten Lammens/Greta van de Sompel in Belgium) for safe, targeted treatment.

No easy DIY fix for this scale.
