How do gnats get into a refrigerator?

Gnats can enter a refrigerator through small gaps or openings, such as around the door seal or ventilation areas. They are often attracted to food residues or spills inside the fridge, particularly if produce or other organic materials are stored without proper sealing. Additionally, if items brought into the refrigerator contain gnat eggs or larvae, they can inadvertently introduce these pests. Keeping the fridge clean and sealing food properly can help prevent their entry.
