Quick Answer
Chemical repellents can be effective against horseflies, but it's essential to use them safely and follow guidelines to minimize risk to skin and health.
Choosing the Right Repellent
When selecting a chemical repellent for horseflies, look for products containing DEET (20-30%), picaridin (20%), or oil of lemon eucalyptus (30%). These concentrations are generally considered safe and effective. Apply repellents only to exposed skin and clothing, avoiding eyes, mouth, and open wounds.
Application and Safety Precautions
Apply repellents according to the product’s instructions, typically 15-30 minutes before heading outdoors. Reapply every 4-6 hours or after swimming or excessive sweating. Wear protective clothing, including long sleeves, pants, and a hat, to reduce exposure. Avoid using multiple repellents simultaneously, as this can increase the risk of adverse reactions. Wash skin and clothing thoroughly after returning indoors.
Additional Prevention Strategies
In addition to using chemical repellents, incorporate other prevention methods into your hunting routine. These include wearing light-colored clothing, which makes it easier to spot horseflies, and avoiding areas with standing water, where horseflies are more common. Use a fan or other airflow devices to keep horseflies at bay, and consider using a mesh screen or net to protect your face and neck.
