1. Understanding Black Flies and Their Behavior
To effectively combat black flies, it’s crucial to understand their behavior and habitat. Black flies, also known as buffalo gnats or turkey gnats, are small insects that thrive in fast-flowing water sources. Knowing when they’re most active and where they breed can help you take preventive measures.
1.1 What Are Black Flies?
Black flies (Simuliidae) are tiny, blood-sucking insects that can be a significant nuisance, especially in wooded areas near rivers and streams. They are known for their persistent biting and the irritating welts they leave behind.
According to Penn State Extension, black flies are most abundant in areas with clean, flowing water, which is essential for their larvae to develop. Adult black flies are typically 1/8 inch long and can fly several miles from their breeding sites.
1.2 When Are Black Flies Most Active?
Black flies are most active during daylight hours, particularly in the late morning and early afternoon. Their peak season is typically from mid-May to July, depending on the region and weather conditions.
“Black fly season generally corresponds with warmer weather and the availability of fast-flowing water,” explains entomologist Dr. Doug Pfeiffer from Virginia Tech. “Understanding this timing is key to minimizing exposure.”
1.3 Where Do Black Flies Breed?
Black flies breed in clean, fast-flowing water such as rivers, streams, and brooks. The female black flies lay their eggs on submerged rocks, vegetation, or other surfaces in these waterways. The larvae attach themselves to these surfaces and feed on organic matter in the water.
A study by the University of New Hampshire found that controlling black fly populations requires targeting their breeding sites. “Effective black fly management involves identifying and treating breeding sites with larvicides that are safe for the environment,” the study noted.
2. Effective Strategies to Repel Black Flies
Several strategies can help you repel black flies and minimize their bites. These range from wearing protective clothing to using natural and chemical repellents.
2.1 Protective Clothing: Covering Up
One of the simplest and most effective ways to prevent black fly bites is to wear protective clothing. Covering as much skin as possible reduces the areas where black flies can bite.
2.1.1 Long Sleeves and Pants
Wearing long-sleeved shirts and pants is essential when spending time outdoors during black fly season. Choose light-colored clothing, as black flies are attracted to dark colors.
“Light-colored clothing can make you less attractive to black flies,” advises the Maine Forest Service. “Covering exposed skin is your first line of defense.”
2.1.2 Hats with Netting
Black flies often swarm around the face, making a hat with attached netting a valuable asset. These nets provide a physical barrier, preventing black flies from reaching your face and neck.

“A head net is a must-have for anyone spending time in areas with high black fly populations,” says outdoor expert Emily Johnson. “It provides instant relief and protection.”
2.2 Natural Repellents: Harnessing Nature’s Power
Several natural repellents can help keep black flies away. These options are often preferred by those looking to avoid harsh chemicals.
2.2.1 Vanilla Extract
Vanilla extract is a popular natural repellent. Applying a small amount to your skin can help deter black flies. Its pleasant scent is a bonus for many users.
“Vanilla extract is a surprisingly effective repellent,” notes herbalist Sarah Thompson. “It’s safe for most people and has a nice fragrance.”
2.2.2 Lavender Oil
Lavender oil is another natural option with a pleasant scent. Its insect-repelling properties can help keep black flies at bay. Dilute lavender oil with a carrier oil, such as coconut or almond oil, before applying it to your skin.
According to a study in the Journal of Economic Entomology, lavender oil has shown repellent activity against various insects. “Lavender oil contains compounds that interfere with the insect’s sense of smell, making it difficult for them to locate their host,” the study explains.
2.2.3 Pine Extract
Extract from pine branches can also act as a natural repellent. Breaking open a young pine branch and rubbing the moisture from inside on your skin can provide some protection.

“Pine extract contains compounds that are naturally repellent to black flies,” explains forester John Davis. “It’s a simple and effective remedy when you’re out in the woods.”
2.3 Chemical Repellents: DEET and Permethrin
When natural repellents aren’t enough, chemical repellents containing DEET or permethrin can provide stronger protection.
2.3.1 DEET
DEET (N,N-Diethyl-meta-toluamide) is a common ingredient in insect repellents. It is effective against a wide range of insects, including black flies. However, its effectiveness against black flies can vary.
“DEET is a reliable repellent, but its effectiveness against black flies can be unpredictable,” cautions Dr. Mark Hansen, an entomologist at the University of Florida. “Some people report that DEET sprays even attract black flies.”
2.3.2 Permethrin
Permethrin is another chemical repellent that is more likely to be effective against black flies. It is often used to treat clothing and gear, providing a longer-lasting barrier.
“Permethrin-treated clothing can significantly reduce your risk of black fly bites,” advises the CDC. “However, permethrin is more toxic than DEET and should be used with caution.”
2.4 Avoiding Attractants: Reducing Your Appeal
Black flies are attracted to certain scents and substances. Avoiding these attractants can help reduce your risk of being bitten.
2.4.1 Sweet-Smelling Perfumes and Lotions
Avoid wearing sweet-smelling perfumes, lotions, and fabric softeners when outdoors. These scents can attract black flies and other biting insects.
“Black flies are drawn to sweet fragrances,” warns dermatologist Dr. Lisa Garner. “Opt for unscented products when spending time outdoors.”
2.4.2 Sugary Foods and Drinks
Indulging in candy or soft drinks outdoors can also attract black flies. The sugar in these items can make you more appealing to insects.
Soft Drink – Cola
“Sugary substances can act as a magnet for black flies,” notes nutritionist Amy Collins. “Choose healthier, less sugary options when you’re outside.”
2.5 Physical Barriers: Creating Bug-Free Zones
Creating physical barriers can help keep black flies away from your immediate environment.
2.5.1 Fans
Using a fan can create a wind barrier that makes it difficult for black flies to fly near you. This is a chemical-free way to keep them away from your porch or outdoor seating area.
“Fans are surprisingly effective at deterring black flies,” says outdoor living expert Tom Stevens. “The moving air disrupts their flight patterns and keeps them away.”
2.5.2 Window Screens and Bug Zappers
Ensure that your windows and doors have screens to prevent black flies from entering your home. Bug zappers can also help reduce the number of black flies in your yard, but their effectiveness can be limited.
According to a study by the University of Delaware, bug zappers primarily attract and kill non-biting insects. “While bug zappers may kill some black flies, they are not a reliable method for controlling their populations,” the study concludes.
3. Home Remedies to Keep Black Flies Away
Several home remedies have been suggested to repel black flies. While their effectiveness can vary, many people find them helpful.
3.1 Apple Cider Vinegar
Apple cider vinegar (ACV) is an old-time remedy that some people believe helps repel black flies. Taking a tablespoon of ACV three to four times a day, starting several days before your outdoor activity, may help your skin ward off biting insects.

“Apple cider vinegar can alter your body odor, making you less attractive to black flies,” explains holistic health practitioner Dr. Megan Edwards. “However, it’s important to consult with your doctor before starting any new supplement regimen.”
3.2 Garlic
Eating garlic is another home remedy that some people use to repel black flies. The sulfur compounds in garlic are believed to make your skin less appealing to insects.

“Garlic contains allicin, a compound that can be released through your skin and act as a natural repellent,” notes nutritionist Rachel Miller. “Eating a clove of garlic a day may help keep black flies away.”
3.3 Essential Oil Blend
Creating a blend of essential oils known for their insect-repelling properties can be an effective home remedy. Mix essential oils like eucalyptus, tea tree, and citronella with a carrier oil and apply to your skin.
“Essential oils can provide a natural and pleasant-smelling alternative to chemical repellents,” says aromatherapist Laura Peterson. “Just be sure to dilute them properly to avoid skin irritation.”
4. Soothing Black Fly Bites
Despite your best efforts, you may still get bitten by black flies. Knowing how to treat the bites can help relieve the itch and prevent infection.
4.1 Washing the Affected Area
Wash the affected area with soap and warm water as soon as possible after being bitten. This helps remove any saliva or other irritants left by the black fly.
“Washing the bite area is the first step in preventing infection,” advises nurse practitioner Susan Baker. “Use a gentle soap and avoid scrubbing too hard.”
4.2 Avoiding Scratching
Avoid scratching the bites as much as possible. Scratching can break the skin, increasing the risk of infection.
“Scratching can lead to secondary infections, which can prolong the healing process,” warns dermatologist Dr. Michael Davis. “Try to resist the urge to scratch.”
4.3 Topical Treatments
Apply a topical agent to soothe the itch. Options include aloe vera, witch hazel, calamine lotion, and antihistamine creams.
4.3.1 Aloe Vera
Aloe vera has soothing properties that can help relieve the itch and inflammation caused by black fly bites.
“Aloe vera is a natural anti-inflammatory that can provide quick relief from itching,” says herbalist Emily Carter. “Apply it liberally to the affected area.”
4.3.2 Witch Hazel
Witch hazel is a natural astringent that can help reduce swelling and inflammation. Apply it to the bite area using a cotton ball.
“Witch hazel can help dry out the bite and reduce inflammation,” explains pharmacist David Wilson. “It’s a gentle and effective remedy.”
4.3.3 Calamine Lotion
Calamine lotion is a classic remedy for insect bites. It contains zinc oxide, which helps soothe the skin and relieve itching.
“Calamine lotion is a go-to remedy for insect bites,” notes dermatologist Dr. Sarah Johnson. “It creates a protective barrier on the skin and reduces itching.”
4.3.4 Antihistamine Creams
If the itching persists or is very bad, an antihistamine cream may be needed. These creams block the histamine response that causes itching.
“Antihistamine creams can provide significant relief from itching,” advises allergist Dr. Robert Miller. “However, they should be used sparingly and according to the instructions.”
5. Public Health Measures for Black Fly Control
In some areas, public health agencies implement measures to control black fly populations. These efforts often focus on targeting black fly larvae in their breeding sites.
5.1 Larvicides
Larvicides are used to treat rivers and streams where black flies breed. These treatments target the larvae, preventing them from developing into adult flies.
“Larviciding is an effective method for controlling black fly populations,” explains environmental scientist Dr. Lisa Thompson. “However, it’s important to use larvicides that are safe for other aquatic organisms.”
5.2 Community Programs
Some communities have established programs to monitor and control black fly populations. These programs may involve regular surveys of breeding sites and the application of larvicides.
“Community-based black fly control programs can be very successful,” notes public health official Michael Davis. “They require collaboration between residents, local government, and public health agencies.”
