Gnats and fruit flies have a lot in common—namely that they are both really tiny, gross and annoying. Although gnats and fruit flies look similar at first glance (or swat, as it were), it’s relatively easy to distinguish between the two if you look a little closer. According to the pest experts at Orkin, fruit flies and gnats differ in terms of color and body shape; they’re also drawn indoors for different reasons.
Fruit flies look a lot like a miniature version of the common house fly in terms of body shape—meaning that they’re relatively round with prominent, bulging eyeballs (ew). In terms of color, fruit flies tend to fall somewhere on the tan-dark brown spectrum. Gnats, on the other hand, tend to have pointier bodies and dangling legs (think: miniature mosquito); they also have far less noticeable eyes and are almost always dark gray to black in color.
Still not sure what you’re dealing with? Gnats feed on fungus and hang around soil, so they often enter the home by way of potted plants—and once they’re inside, that’s where you’re most likely to find them hanging out. Fruit flies, as their name suggests, are attracted to fruit—particularly the overripe or fermented variety. That said, both these pesky creatures procreate at an alarming rate.
