The Bug You Didn't know You Were Eating

How tiny bugs became the world's favorite dye

Imagine stumbling upon a bunch of tiny bugs crawling on a cactus and thinking, “Hey, these would be perfect for my next cake!” Sounds strange, right? But that’s pretty much what happened with cochineal, a small insect that has shaped the world’s favorite color—brilliant red.


Long before Europe knew about cochineal, the Aztecs and Mixtec people of Mesoamerica had already figured out the secret. They discovered that by crushing these little critters, they could produce an incredibly vibrant red powder. This powder was then mixed with water to make a dye so striking that it became a symbol of power, used in ceremonial clothing, art, and everything fancy. 


This dye was far superior to anything else available in the world—it didn’t fade easily, and the color was intense, unlike the muddy reds produced by other dyes.


When Hernán Cortés arrived in the Americas during the Spanish conquest in the early 16th century, he was dazzled—not just by gold and silver but by the rich, colorful textiles that the Aztecs had. Among all these treasures, the cochineal dye stood out. Cortés, ever the opportunist, recognized the value of this "red gold" and sent news of it back to Spain. And just like that, cochineal went from being a Mesoamerican secret to a European obsession.


The Spanish, of course, wanted to keep the source of this incredible dye to themselves. They tightly guarded the secret—tiny insects on prickly pear cacti—and turned cochineal into one of the most lucrative exports of the Americas, second only to silver. Suddenly, everyone in Europe wanted the vivid scarlet that cochineal could provide. Kings and queens, the church, and the wealthy were all clamoring for the brilliant red fabric that symbolized prestige and wealth.


But it wasn’t just about clothing. Once cochineal made its way into Europe, people quickly realized its potential for food and cosmetics. Confectioners started experimenting, using it to color candies, pastries, and syrups. Unlike many other dyes of the time, cochineal was non-toxic, which made it perfect for anything people wanted to eat or drink. The same deep red that decorated royal robes could now color your cake, too!


The craze continued for centuries. Even today, cochineal is used in foods and cosmetics—those red candies or that crimson lipstick? Chances are they owe their brilliant hue to these little bugs.
