Professor Reveals Face-Dwelling Mites on Irish Radio Show

Listeners of RTÉ Radio 1’s The Brendan O’Connor Show were left both shocked and intrigued when Professor Christine Loscher, an expert in immunology at Dublin City University (DCU), revealed that tiny mites live on human faces. This surprising discussion took place on the morning of March 23, 2024, during a segment focused on allergies and common household pests.

Prior to discussing facial mites, the conversation began with the topic of dust mites, microscopic creatures that thrive in homes with warm and humid conditions. Professor Loscher explained that these spider-like organisms feed on shed human skin cells, multiplying in bedding, carpets, and even children’s toys. Their waste contains proteins that can trigger allergic reactions, leading to symptoms like sneezing and watery eyes, particularly during cleaning or changing sheets.

The professor highlighted the alarming reproductive capacity of female dust mites, which can lay as many as 200 eggs at a time. This rapid population growth often peaks in winter when homes are sealed and heating systems are activated. According to Loscher, dust mites prefer cozy, humid environments such as pillows, duvets, and sofas, where skin cells accumulate.

As the discussion progressed, O’Connor posed a question that shifted the focus to another type of mite. “Are there mites that live directly on people’s bodies?” he asked. Professor Loscher’s response confirmed the unsettling reality: “Yes, we have little mites that live on our face.”

These mites are known as Demodex mites, and they require a human host to survive. Professor Loscher elaborated, stating, “They tend to live a lot on the face; they tend to be kind of in your eyelashes; and they tend to cause a lot of irritation on the face, around the eyes.” She noted that these microscopic parasites can be transmitted from person to person through physical contact.

The implications of her statements left O’Connor visibly unsettled. “Okay, I can’t take any more. Thank you very much for that, Professor Christine Loscher. I’m now wiping imaginary mites off my face,” he humorously remarked, before cutting to a break.

This revelation about the existence of Demodex mites serves as a reminder of the unseen organisms that share our living spaces, prompting listeners to reconsider their daily hygiene practices. The discussion illustrates the importance of understanding how common household pests can impact health, particularly for those with allergies or sensitive skin.
