A few weeks ago, I was hiking with my sister and my best friend, Thomas. We had stopped near an old wall covered with ivy when suddenly I felt a little prick under my ankle. Surprise! A tiny spider had bitten me. I then heard Sophie scream, “Destroy it quickly!” But I definitely didn’t want to burn the creature—a reaction I regret after reading some alarming myths. That morning, between the damp smell of the undergrowth and the distant song of cicadas, I realized it was time to untangle truth from falsehood.
Sommaire
Myth #1: “If it’s small, it’s not dangerous”
We often believe that the smaller the spider, the more harmless its bite. Yet, some microscopic species secrete formidable toxins. Take the example of Loxosceles reclusa, the brown recluse: it barely measures 7 mm, and its venom can cause severe skin necrosis. When I was a kid, my grandfather always told me, “It’s not the size that counts, it’s the dose!” Well, that’s exactly it; a small creature can have a very powerful venom.
Myth #2: “Red spiders are the most venomous”
Color attracts: we imagine the dreaded red spider as the most toxic of all. But the reality is different. Many harmless species display a reddish-brown or dull red color to camouflage themselves in soil or dead leaves. On the other hand, the Phoneutria fera from South America remains beige and black and is one of the most venomous. So yes, color can mimic a warning signal (aposematism), but it alone is not a guarantee of danger.
Myth #3: “Burning the bite deactivates the venom”
This is the classic grandmother’s advice: cigarette burn, lighter, 90° alcohol… We imagine that heat will neutralize the injected venom. Bad idea! First because you risk burning your skin, and second because the venom, once in the body, does not stay on the surface. It’s a bit like pouring boiling water on an oil stain: you can drown the surface, but the fire is already under the oil.
Myth #4: “You absolutely must cut the bitten area”
Another popular belief is that to prevent the spread of venom, you must make an incision around the bite. I admit this practice sends chills down my spine. Not only does it increase the risk of infection, but it does not guarantee the elimination of venom. In reality, a gentler method consists of cleaning with lukewarm water, applying a sterile dressing, and monitoring the progression. To learn more about how to recognize and effectively treat a spider bite, you can consult specialized guides.
Myth No. 5: « Venom always kills if you don’t act quickly »
In movies, we often see the character fade away within minutes after a deadly bite. Fortunately, reality is more nuanced. While some bites are potentially fatal (like certain black widows), most mainly cause pain, swelling, and mild fever. Severe cases require hospitalization, but luckily this is not the norm. My friend Julien, an emergency doctor, reminds me that much of the treatment’s success depends on appropriate medical care rather than initial panic.
Myth No. 6: « Grandma’s remedies are always enough »
Garlic, onion, lemon juice… There is a whole « remedy tree » found in households. However, while these preparations can relieve itching, they do not act on the toxin. In the countryside, my aunt Louise systematically applied cold butter on the bite to soothe the burning. It surely relieved the burning sensation, but not the spread of the poison. To truly neutralize the pain, it is better to use prescription anti-inflammatories and careful monitoring.

Rather than giving in to preconceived ideas, here is a simple method:
- Clean the area with fresh water and soap.
- Apply a sterile dressing and, if needed, a mild antiseptic.
