When to worry about a guide spider bite?


Spiders are often considered unattractive, intrusive, and unpleasant by many Americans. For individuals with arachnophobia, their fear of spiders may stem from an instinctive response, as spiders have long been associated with illness and infections.

Encountering these leggy intruders can quickly provoke feelings of panic, serving as a reminder that nature surrounds us despite our best efforts to keep it at bay. While we usually strive to maintain a safe distance from spiders, an unfortunate encounter—such as crushing them under a shoe or unknowingly disturbing them beneath a stored blanket—can result in the dreaded spider bite.

Despite our deep-seated fear and aversion, it is essential to determine when to worry about a spider bite and when it necessitates immediate medical attention.

What does a spider bite look like?

Spider bites often resemble regular insect bites, presenting as a red, painful bump on the skin that may itch. In cases where the bite is harmless, this is typically the only symptom experienced. However, it is crucial to be mindful of other symptoms that may arise if bitten by a black widow or brown recluse spider, as there are two specific reasons to pay attention to them.

Symptoms of black widow spider bite

If bitten by a black widow spider, the pain can extend from the bite area to the stomach, back, or chest. Certain individuals may also encounter intense abdominal cramps and excessive sweating either localized at the bite site or throughout the affected body part.

If you suspect a black widow spider bite, it is crucial to seek immediate medical help. It is especially important to be cautious with children and elderly adults, as these bites can have severe consequences for them.

Symptoms of  brown recluse spider bite

Bites from a brown recluse spider exhibit different effects compared to those from a black widow. The pain surrounding the bite gradually worsens within the initial eight hours. The bite mark itself may darken and transform into a deep skin ulcer as the surrounding tissue becomes necrotic.

If you suspect a bite from a brown recluse spider, it is crucial to seek immediate medical assistance. It is particularly important to exercise caution with children and elderly adults, as these bites can have severe consequences for them.

Although infrequent, occurrences of black widow and brown recluse spider bites do happen. Most of the time, spiders do not bite unless they feel startled or threatened, as their venom is primarily intended for subduing prey rather than harming humans who would prefer to avoid an encounter with these dangerous creatures.
