Horseflies Explained

Horseflies have earned a reputation with their painful bites and relentless pursuit of blood meals. But have you ever wondered why these insects bite and how they got their peculiar name?

‍

Horseflies, scientifically known as Tabanidae, belong to a family of true flies notorious for their painful bites. Unlike mosquitoes with a piercing proboscis, horseflies have scissor-like mouthparts designed to cut into flesh.

‍

Like mosquitoes, female horseflies require blood to develop their eggs. Using specialized sensors, the female flies search for body heat, exhaled carbon dioxide, and visual cues to find their next meal.

‍

Interestingly, not all horseflies are bloodsuckers. Male horseflies feed on nectar and other plant juices, not needing to find blood to sustain them. However, when feeling threatened, they may also resort to biting as a defensive mechanism.

‍

But why are they called horseflies?

‍

‍

The name "horsefly" might suggest a preference for horses, but these insects are equal-opportunity biters. While horseflies do bite horses, they are not exclusive to them. They will bite many animals, including cattle, deer, and humans– targeting whatever warm-blooded host is available.

Can You Be Allergic to Horsefly Bites?

Horsefly bites can cause various responses in humans; some may even be allergic to horsefly bites! For example, you may experience the following symptoms after a nasty run-in with one of these pests.

‍

• Localized Reactions: Most people will have localized reactions to horsefly bites. These reactions typically include pain, itching, redness, and swelling at the bite site. These symptoms are not considered an allergic reaction but are the body's natural response to the bite.
• Systemic Allergic Reactions: Individuals may sometimes experience systemic allergic reactions to horsefly bites. These reactions can include hives, generalized itching, difficulty breathing, swelling of the face or throat (angioedema), dizziness, and even anaphylaxis in severe cases. Anaphylaxis is a life-threatening allergic reaction that requires immediate medical attention.
• Secondary Infections: Horsefly bites can become infected if bacteria enters the broken skin. While not an allergic reaction, secondary infections can occur and may require medical treatment.

‍

Not everyone who is bitten by a horsefly will have an allergic reaction. Allergic reactions to insect bites, including those from horseflies, are relatively rare but can be severe when they occur.

‍

If you suspect you are experiencing an allergic reaction to a horsefly bite or have a history of severe allergic reactions to insect bites, seek medical attention promptly!

Treating an Allergic Reaction to a Horsefly Bite

Treating an allergic reaction to a horsefly or insect bite should be taken seriously. Take a look at our tips to know what to do if you have an adverse response to a bite.

‍

• Seek Medical Help Immediately: If you or someone you are with experiences symptoms of a severe allergic reaction (anaphylaxis), such as difficulty breathing, swelling of the face or throat, dizziness, or a rapid drop in blood pressure, call 911 or seek emergency medical assistance immediately. Anaphylaxis is a life-threatening condition that requires immediate intervention.
• Use an Epinephrine Auto-Injector (if prescribed): If the person experiencing the allergic reaction has been prescribed an Epinephrine auto-injector (an EpiPen), it should be administered according to the instructions. Epinephrine can help reverse the symptoms of anaphylaxis and is the first-line treatment for severe allergic reactions.
• Administer Antihistamines: If you're experiencing mild allergy symptoms, use over-the-counter antihistamines like Benadryl to relieve itching and discomfort. Just make sure to follow the dosage instructions on the package. But if you know you have severe allergies, you must consult a doctor and seek emergency help.

‍

After you've taken steps to alleviate the initial reaction and received clearance from a medical professional, follow these tips to prevent further pain or infection from a horsefly bite.

‍

• Apply Cold Compress: A cold compress (a clean cloth soaked in cold water or an ice pack wrapped in a cloth) to the affected area can help reduce swelling and relieve itching.
• Elevate the Affected Area: If possible, raise the area where the bite occurred. For example, elevate the leg if the bite is on the leg.
• Avoid Scratching: It's essential to avoid scratching the bite as this can worsen the reaction and increase the risk of infection.
• Topical Steroids (if prescribed): A healthcare provider may sometimes prescribe topical corticosteroids to reduce inflammation and itching associated with the bite.
• Monitor for Signs of Infection: Keep an eye on the bite site for any signs of infection, such as increased redness, warmth, pus, or worsening pain. If infection is suspected, seek medical attention.
• Follow Up with an Allergist: After experiencing an allergic reaction to a horsefly bite, consulting with an allergist or immunologist is essential. They can perform allergy testing, assess the severity of the allergy, and provide guidance on prevention and management, which may include carrying an epinephrine auto-injector.

‍

Remember that allergic reactions to insect bites can vary in severity, so it's crucial to err on the side of caution and seek medical attention for any significant or concerning symptoms.
