Quick Answer
Avoid getting bitten by leeches in wetlands by wearing protective clothing, using insect repellent, and keeping your skin dry. Leeches prefer areas with slow-moving water and tend to attach to skin that is already moist.
Prevention Techniques
When navigating wetlands, wear long pants, long-sleeved shirts, and closed-toe shoes to minimize exposed skin. This protective clothing can be layered under a waterproof jacket or poncho to prevent water from penetrating to your skin. Additionally, apply insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin and clothing.
Avoiding Leech Habitats
Leeches thrive in slow-moving or stagnant water with abundant vegetation. Steer clear of these areas by staying on raised banks or elevated platforms, such as boardwalks or tree roots. When walking through wetlands, try to stay on established trails to avoid wandering into leech-infested areas. If you must cross a wet area, do so quickly and carefully, avoiding prolonged exposure to water.
Additional Precautions
After navigating wetlands, inspect your skin regularly for leeches. Use a magnifying glass or a bright light to spot leeches, which can be as small as a grain of rice. If you do find a leech attached, use fine-tipped tweezers or a credit card to carefully remove it, taking care not to squeeze the leech and cause it to release its anticoagulant saliva.
