Flies are a nuisance. You have probably seen flies both indoors and outdoors, buzzing around and landing on kitchen counters and right on your food. There’s a good chance you also already know flies are unsanitary because they tend to land on garbage, feces and other dirty objects. This causes the flies to pick up bacteria, which they can transfer to food and cooking surfaces which can create health risks for you. But did you know some fly species bite?
Several species of fly need blood in order to reproduce and will gladly bite humans to get this blood. These flies need the proteins to create eggs. When it comes to pest control, Western Exterminator pest control technicians are experts in most fly species, including biting flies. We can help you get rid of flies in your home and around your property. Contact your local Western Exterminator office today.
Flies do not need to consume blood in order to live. So, why do flies bite in the first place? Most species of flies prefer other food sources, such as nectar from plants. However, for reproduction, flies need the proteins found in animal blood in order to mate and produce eggs.
Flies have special mouthparts like mosquitoes, fleas, ticks and bed bugs, allowing them to pierce the skin and access blood vessels. They also inject anticoagulants contained within their saliva, which allows the blood to flow freely into their bodies.
Why do flies bite humans? As noted above, biting flies like horseflies or black flies need the protein in blood to produce eggs and complete their life cycle. Human skin offers easy access to blood vessels, especially in warm weather when more skin is exposed. Some people may also be more attractive to flies due to body heat, sweat, or scent.
If you’re experiencing biting flies on your property, our fly pest control services can help address the problem.
Fly bites do carry some potential health risks. Some viruses and bacteria can be carried by the insects in their systems, which can be transmitted to humans and animals via their saliva. Fortunately, the biggest risks tend to affect other animals. Horse flies, for example, can carry anthrax, which they can transmit to sheep or cattle. However, some species of biting flies can transmit diseases such as:
The bites of black flies, stable flies, and horse flies can be painful to humans, and those sensitive to insect bites and stings can experience allergic reactions.
It can depend on the species, but most bites involve a sharp, painful sting. Flies slice or pierce the skin to draw blood, leaving behind a red bump, rash, or welt. The bite area may become itchy, swollen, or even bruised. In rare cases, bites may lead to infection or a severe allergic reaction, especially if the fly introduces bacteria into the site of the bite.
Some flies can spread illnesses like rabbit fever (Tularemia) or affect the lymph nodes, though this is uncommon. If you notice symptoms like fever, wheezing, or spreading redness around the affected area, speak with a healthcare provider.
While people often find that treating fly bites with cold packs and/or antihistamine is sufficient, you should always seek medical attention if symptoms get worse.
Fly bites may look different depending on the species involved. Since each species of fly is a little different, it can depend on where you are and which fly has chosen you for its blood meal.
So why do flies bite before it rains? The simple answer is that fly behavior changes with the weather. When the air gets more humid or pressure drops, flies become more active. These conditions often signal rain. Female flies may bite more often to feed before sheltering from the storm.
In some parts of the United States, this can lead to a noticeable rise in fly bites right before bad weather hits. While this behavior isn’t fully understood, experts believe weather shifts may trigger instinctive feeding.
Using light repellents like picaridin can help reduce bites, but for longer-term protection, speak to one of our pest control experts about fly management at your home or business.
