1. Understanding Gnats and Their Attraction

1.1 What Exactly Are Gnats?

Gnats are tiny, two-winged flies belonging to several families within the order Diptera. These small insects are often mistaken for fruit flies or mosquitoes, but they have distinct characteristics and behaviors. According to the University of California, Agriculture and Natural Resources, gnats are typically attracted to moisture, decaying organic matter, and carbon dioxide.

1.2 Why Are Gnats Attracted to Faces?

Several factors attract gnats to human faces:

• Moisture: Gnats are drawn to moisture, including sweat, tears, and saliva. The areas around the eyes, nose, and mouth provide the perfect environment for them.

• Carbon Dioxide: Like mosquitoes, gnats are attracted to the carbon dioxide that humans exhale. The face, being the primary source of exhalation, becomes a focal point.

• Lachrymal Fluids: As mentioned in The Gazette, gnats are attracted to the lachrymal fluids that keep our eyes lubricated.

• Odor: Body odor and fragrances from perfumes or lotions can also attract gnats.

1.3 Types of Gnats Commonly Found

Different types of gnats exhibit slightly different behaviors. Some common types include:

• Fungus Gnats: These are often found indoors, especially near houseplants. They thrive in moist soil and decaying organic matter.

• Fruit Flies: While technically not gnats, fruit flies are similar in size and behavior. They are attracted to ripe and fermenting fruits and vegetables.

• Eye Gnats: These are particularly drawn to the moisture around the eyes. They are known to transmit certain eye diseases.

• Buffalo Gnats (Black Flies): These are more aggressive and can bite, causing itching and swelling. According to Mississippi State University Extension, buffalo gnats thrive in flowing water and can be a nuisance in late spring and early summer.

2. Health and Safety Concerns
