Figs don’t contain worms, but some figs do contain the remnants of a tiny wasp. The fig and its pollinating wasp have co-evolved one of nature’s tightest partnerships: the wasp pollinates the fig’s internal flowers, and the fig provides a place for the wasp’s offspring to develop. What people sometimes see inside a fig and mistake for a worm is usually a dead wasp or, more often, nothing at all, because the fig has already broken it down by the time you eat it.
Why Wasps End Up Inside Figs
Figs are unusual fruits. What looks like a single fruit is actually an inside-out cluster of tiny flowers, all enclosed in a fleshy shell. The only way pollen can reach those flowers is through a narrow opening at the bottom called the ostiole. Fig-pollinating wasps, which are roughly 1 to 2 millimeters long, squeeze through this opening to lay their eggs inside. The passage is so tight that the wasps lose their wings and parts of their antennae on the way in. They don’t come back out.
Once inside, the female wasp pollinates the flowers and lays eggs in some of them. Each wasp larva develops by consuming the contents of one would-be seed. After the offspring mature and mate inside the fig, the new females collect pollen, exit through the ostiole, and fly to another fig tree to repeat the cycle. The original mother wasp, however, dies inside the fig.
This is where the “worms in figs” idea comes from. The small, pale wasp larvae developing inside the fig could look worm-like to someone who cut open an unripe or wild fig at the wrong stage. But these aren’t parasitic worms. They’re part of a pollination system that has existed for roughly 80 million years.
Most Grocery Store Figs Never See a Wasp
The figs you buy at a supermarket almost certainly developed without any wasp involvement. Common commercial varieties like Brown Turkey and Hardy Chicago produce fruit through a process called parthenocarpy, meaning the fruit develops from unfertilized flowers without pollination. No wasp enters the fig, no eggs are laid, and no remnants are left behind. These varieties dominate grocery store shelves and home gardens in most of the United States and Europe.
Some fig types, known as Smyrna and San Pedro varieties, do require wasp pollination to produce fruit. California’s Calimyrna fig (a Smyrna type grown for drying) is the most commercially significant example. Growers actually introduce pollinator wasps deliberately to ensure these trees set fruit. If you eat dried Calimyrna figs, a wasp entered each one during its development.
What Happens to the Wasp Inside
Even in wasp-pollinated figs, you’re not eating an intact insect. Figs produce an enzyme called ficin, a protein-digesting compound that breaks down the wasp’s body after it dies inside. By the time the fig ripens, the wasp has been almost entirely decomposed and absorbed into the fruit’s tissue. You won’t find a recognizable insect when you bite into a ripe fig. The crunchy bits you feel are seeds, not wasp parts.
The occasional dark or slightly different-textured seed you notice is just that: a seed. Some seeds were pollinated and are viable, while others developed without fertilization. Neither contains insect material in any form you could detect by taste or texture.
FDA Standards for Insect Content in Figs
Like all agricultural products, figs can pick up insects during growing and processing. The FDA maintains specific thresholds for allowable insect content in fig products. For whole figs, the action level is reached when 10% or more of the fruit pieces are insect-infested, moldy, or contaminated. For fig paste, the threshold is 13 or more insect heads per 100 grams. Below these levels, the product is considered safe and normal for a food that grows outdoors.
These standards exist for virtually every fruit, grain, and spice. Figs aren’t unusually buggy compared to other produce. The guidelines simply reflect the reality that some level of insect contact is unavoidable in agriculture and poses no health risk.
Crunchy Seeds vs. Actual Insects
If you’ve bitten into a fig and felt something unfamiliar, the explanation is almost always seeds. A single fig can contain hundreds to over a thousand tiny seeds, and their texture varies depending on the variety and ripeness. Fresh figs tend to have softer seeds, while dried figs concentrate those seeds into firmer, more noticeable crunchiness.
The stringy fibers you sometimes see when pulling apart a dried fig are vascular tissue from the fruit itself, not anything insect-related. And the hollow center common in many fig varieties is simply the interior cavity where the flowers once faced inward. None of these normal features indicate the presence of worms or insects.
If you’re specifically concerned about eating wasp-pollinated figs, stick to common varieties like Brown Turkey, Celeste, or Kadota, all of which fruit without pollination. If you enjoy Calimyrna or other Smyrna-type dried figs, the wasp involvement is real but the enzyme digestion is thorough. What you’re eating is fig.
