ToggleNothing ruins outdoor fun faster than a swarm of biting black flies. These pests can quickly disrupt backyard barbecues, family gatherings, and any time spent enjoying the Florida sunshine. At On Demand Pest Control, we understand the frustration of dealing with black flies and are here to help.
Black flies, often mistaken for house flies, are not only annoying but can also leave itchy, painful bites. Female black flies require blood meals to lay their eggs, which they often deposit near flowing water or damp surfaces. Their lifecycle—from egg to adult—varies depending on environmental factors like water temperature and food availability. Once mature, female black flies seek their next blood meal, leaving behind bites that can cause swelling and irritation. In rare cases, black fly bites can even lead to black fly fever, with symptoms such as fever, nausea, and swollen glands.
If you’re wondering how to get rid of black flies in your Florida yard, you’ve come to the right place. Read on to learn more about these pests and how On Demand Pest Control can provide effective solutions to keep your outdoor spaces comfortable and pest-free.
What Makes Black Flies Dangerous?
Black flies differ significantly from common house flies in behavior and the problems they cause:
House Flies: These pests breed in filth, spread diseases like dysentery and diarrhea, and contaminate food.
Black Flies: They breed in flowing water or on damp surfaces. While not known to spread deadly diseases in North America, their bites can cause severe itching, swelling, and irritation. In rare cases, black fly fever may occur, leading to fever, nausea, and swollen glands.
Black flies are tiny, measuring about one-eighth of an inch in length, with a hump-backed appearance. They are sometimes called “buffalo gnats” or “turkey gnats.” Although not all species bite humans, even non-biting types can swarm around your face, crawling into your eyes, nose, and ears, making them unwelcome visitors to your yard.
How to Get Rid of Black Flies in Your Yard
Black flies typically breed near running water, such as rivers, streams, and lakes. However, they can fly 7 to 10 miles from their breeding grounds, making them a nuisance even for those who don’t live near water.
Here are some practical steps you can take to control black flies in your yard:
1. Eliminate Breeding Grounds
Remove Standing Water: Regularly empty items like birdbaths, flowerpots, and buckets that can collect water.
Clean Gutters: Ensure your gutters are clear of debris to prevent water from pooling.
2. Use Physical Barriers
Install Fans: Black flies are weak fliers and struggle to land in areas with moving air. Adding fans to your patio or outdoor seating areas can help.
Wear Protective Clothing: Light-colored, long-sleeved shirts and pants can deter bites. Hats with netting provide additional protection.
3. Apply Natural and Chemical Repellents
Use Essential Oils: Citronella, lemongrass, and lavender oils can help repel black flies naturally.
Insecticides: For more severe infestations, professional-grade insecticides can target larvae and adults effectively.
Preventing Black Flies Long-Term
Prevention is the key to keeping your yard black-fly-free year-round. Here are some tips to maintain a pest-free environment:
-
Maintain Landscaping: Keep shrubs and grass trimmed to reduce hiding spots for black flies.
-
Inspect Outdoor Areas: Check for signs of black fly activity regularly, especially near water features or damp areas.
