Final answer:
The tiny bugs crawling on human faces are likely common dust mites, tiny organisms about half a millimeter in size. Reducing dust mite populations involves thorough cleaning, using allergen-impermeable covers, washing bedding in hot water, maintaining low humidity, and using HEPA filters when vacuuming.
Step-by-step explanation:
The tiny creatures you are referring to are likely the common dust mites, which are indeed so small they are barely visible without magnification. Dust mites are microscopic organisms that live in household dust and feed on organic debris, such as human skin cells. The size of a dust mite is approximately half a millimeter, and while they may seem alarming, they are a typical part of the indoor environment.
Although it is impossible to completely eradicate dust mites from your home, as they are ubiquitous and can survive in even the cleanest environments, regular and thorough cleaning can help reduce their numbers. It's important to note that the proteins found in dust mite feces can trigger asthma attacks in some individuals, which is why managing their presence can be particularly important for those with asthma and allergies.
To reduce the number of dust mites, consider using allergen-impermeable covers for mattresses and pillows, washing bedding in hot water regularly, and maintaining a low humidity level in your home. Additionally, vacuuming with a HEPA filter and dusting with damp cloths can help control dust mite populations.
