As a seasoned outdoor writer and adventurer with over a decade spent exploring the backcountry, I can confidently say that few things ruin a beautiful day faster than relentless deer flies. These persistent pests are notorious for their painful bites and ability to drive even the most dedicated outdoor enthusiast indoors. Finding an effective natural deer fly repellent is crucial for enjoying your time in nature. This guide will cover everything you need to know about these buzzing nuisances – from understanding their behavior to implementing strategies to keep deer flies away, including DIY solutions, commercial options, and preventative measures. We’ll even tackle how to kill deer flies when prevention isn’t enough, and explore the effectiveness of things like deer fly hats and deer repellent tape.
Before diving into repellents, it’s important to understand what makes deer flies so… determined. Unlike mosquitoes, both male and female deer flies feed on blood. They are strong fliers, capable of covering significant distances, and are most active during warm, sunny days. According to the Centers for Disease Control and Prevention, deer flies are attracted to dark clothing, movement, and carbon dioxide – just like mosquitoes, but they’re often less deterred by typical mosquito repellents.
The pain from a deer fly bite isn’t just psychological. Deer flies don’t simply pierce the skin; they slash it with their scissor-like mouthparts, creating a small wound. This causes significant irritation and bleeding, making them far more painful than a mosquito bite. The wound can also take longer to heal and is susceptible to secondary infection.
There’s a common myth that deer flies are attracted to blue. While some studies suggest a slight preference, it’s not as strong as often believed. They are more attracted to movement and dark colors. However, using blue deer fly tape can be a surprisingly effective trapping method, as the color does draw them in. We’ll discuss that more later.
Many outdoor enthusiasts prefer to avoid harsh chemicals, making natural deer fly repellent options highly sought after. While their effectiveness can vary, these methods can provide significant relief, especially when combined with other preventative measures.
Several essential oils have shown some repellent properties against deer flies. Here are a few blends to try (always dilute essential oils with a carrier oil like jojoba, almond, or coconut oil before applying to skin):
Important Note: Always perform a patch test before applying any essential oil blend to a large area of skin to check for allergic reactions. The Remedy Health website provides further information on essential oil safety.
Apple cider vinegar is another popular natural repellent. Dilute equal parts apple cider vinegar and water in a spray bottle and apply to exposed skin. Be cautious, as vinegar can be irritating to sensitive skin.
Steeping strong herbal teas (like catnip, rosemary, or lavender) and allowing them to cool can create a spray that offers some repellent effect. Strain the tea thoroughly before applying.
While DIY solutions can be helpful, sometimes you need the power of a commercially formulated deer flies repellent. Look for products containing ingredients like:
Read reviews carefully and choose products specifically labeled for deer fly protection. Remember that even natural repellents should be used as directed.
Sometimes, the best defense is a good offense – or, in this case, a good barrier. Here’s how to physically protect yourself:
A deer fly hat with fine netting is arguably the most effective way to protect your face and neck. These hats create a physical barrier that deer flies simply can’t penetrate. Look for hats with a dark-colored inner lining, as this can further deter flies. I personally recommend a hat with a wide brim for added sun protection.
Wear long sleeves and pants whenever possible. Light-colored clothing is generally preferred, but tightly woven fabrics offer the best protection regardless of color. Consider treating clothing with permethrin (follow label instructions carefully) for added insect repellent properties.
Deer repellent tape, often blue in color, is a sticky tape that you can wrap around your hat, arms, or legs. Deer flies get stuck to the tape, effectively removing them from your immediate vicinity. It’s a messy solution, but it can be surprisingly effective, especially in areas with high deer fly populations. Replacing the tape frequently is key.
Sometimes, despite your best efforts, deer flies will still find a way to bother you. Here’s how to kill deer flies and reduce their numbers in your area:
As mentioned earlier, deer fly tape or commercially available blue sticky traps can be highly effective. Hang them in areas where deer flies are prevalent, such as near wooded areas or water sources.
The classic method! A good old-fashioned fly swatter can be surprisingly effective, especially for targeting individual flies. However, it requires quick reflexes and can be tiring.
While I generally advocate for natural solutions, in some cases, insecticide sprays may be necessary. Use these products sparingly and follow label instructions carefully. Consider using a space spray designed for flying insects.
Beyond repelling and killing deer flies, you can take steps to reduce their populations around your property:
