Bug food for pets was never Plan A — it’s the last resort for insect producers to stay afloat. They blame EU bureaucracy. “I wake up every morning for the fish, not to feed the pets,” said Sébastien Crépieux, CEO of Invers, a French insect producer based in Auvergne-Rhône-Alpes that grows mealworms in cooperation with local farmers. He explains that most insect producers started with the idea of replacing protein in fishmeal used to feed farmed fish with a more sustainable source — such as insects. Fishmeal is usually made from fish processing waste and forage fish like anchovies or sardines, and contributes to overfishing and biodiversity loss. In 2017, the European Commission approved the use of insect protein in aquaculture feed to address that issue. In 2022, it also allowed insects to be used in feed for pigs and poultry. For many in the field, that was a big step forward. “We all developed based on this concept,” said Crépieux. “But unfortunately, the Commission never banned fishmeal, so we’re still competing with a resource taken freely from the ocean at a very low price. Fishmeal imports into Europe must be controlled — we’re really killing the ocean,” he added. According to the 2024 United Nations Food and Agriculture Organization report, 10 percent of fish populations were fished at unsustainable levels in the mid-1970s. The number has almost quadrupled in 2021 to 37.7 percent of stocks. The ambitious EU monitoring rules on fisheries, which came into force last January, introduced electronic tracking systems for vessels and minimum sanctions for violations of the common fisheries policy — but failed to include limits on how much forage fish can be diverted to fishmeal. That’s where insect-based pet food comes in. “If we had to compete by selling our production as fish feed, we would already be dead,” said Crépieux. That is why he, like some other producers, shifted his focus to pet food. FEEDING PETS WITH BUGS Insect-based pet food — marketed as hypoallergenic and more sustainable — remains a niche product embraced mostly by true enthusiasts. Traditional pet food, made from meat or vegetable byproducts or grains, still dominates more than 99.5 percent of the market. According to Crépieux, it’s unlikely this type of pet food will ever become mainstream unless major brands like Purina or Acana adopt it.

I think animals, unlike us, know what’s good for their health — they really eat it,” he said, adding that his cats are happy with this alternative protein. However, green NGOs like Eurogroup for Animals and Compassion in World Farming have questioned its true environmental benefits. “Farming insects has a higher sustainability impact than most traditional pet food ingredients … most insects are not sourced from Europe,” said Francis Maugère of Eurogroup for Animals. “If you want to rear them here, you can — but you must keep them at high temperature and humidity, which comes with financial and energy costs,” he added. The group also argues that there’s insufficient scientific evidence to support the hypoallergenic claims. “The sustainability of insect-based pet food is highly questionable — from insect welfare standards, to the need for diets based solely on byproducts rather than cereals and soy, to its high carbon footprint due to heating requirements,” said Phil Brooke, research and education manager at Compassion in World Farming. FEDIAF, which represents the European pet food industry, called insect-based pet food “one of several promising innovations” in the drive to diversify sustainable protein sources. Cecilia Lalander, a professor at the Swedish University of Uppsala specializing in insect use in waste management, believes using insects for pet food is “not the best use of resources.” “If we’re replacing pet food made from animal byproducts — like slaughter waste, which is already a good use of waste — then it’s really not sustainable,” she said. THE UNSUSTAINABLE LOOP Lack of fishmeal regulation isn’t the only source of frustration for insect producers. The EU classifies insects as farmed animals and prohibits using kitchen waste to feed them. As a result, insects are often raised on the same food processing byproducts — like wheat bran or brewery grains — that are already suitable for feeding pigs and cattle, making insects an unnecessary extra step in the food chain. Lalander argues this is inefficient and unsustainable. “The reason the insect industry can’t be as sustainable as it could be is entirely due to regulations,” she said. Following the mad cow disease (BSE) outbreak in the 1990s, the EU implemented strict rules to prevent a recurrence. It banned the use of processed meat in livestock feed, and ruled that farmed animals — including insects — may not be fed catering waste, as it could contain traces of meat. However, Lalander points out that insects cannot develop or transmit prions, the infectious proteins responsible for BSE, and that health risks are minimal. “The system the EU opposed was the most closed loop imaginable — giving feed originating from the same species, even if they were dead or sick,” she said. “What we propose is using post-consumer food waste to feed insects, which are then used to feed animals.” The European Commission, for its part, disagrees with the view that feeding insects with catering waste is risk-free. “The risks are not limited to BSE and prions only … but related to several transmissible animal diseases,” a Commission official said in response to a POLITICO inquiry. Catering waste may transmit several animal diseases such as African or classical swine fever, foot and mouth disease or avian influenza, the official said, while catering waste has been identified as a possible or likely source of infection in several outbreaks of these diseases in the EU. “Due to the nature of the insects which are living in their feed and are contaminated with their feeding substrate, only feeding substrate already declared safe for farmed animals has been authorized,” added the Commission official, who spoke on condition of anonymity. Several scientific studies have found, however, that these risks can be avoided if food waste is treated properly before feeding it to insects. Such treatment can include fermentation, heat treatment, or drying to remove harmful pathogens that can be found in unprocessed food waste. Lalander argues that regulatory barriers aren’t the only challenge circular business models like the insect one are facing. Long-standing market expectations, shaped by cheap, linear production systems that overlook environmental costs, also pose a significant obstacle. “In a circular business model you pay for every step of the production. But if you look at the world market predominantly it’s a linear economy which means you take product and then you have a waste and that’s it,” Lalander said. She points out that expecting insect feed to be as cheap as fishmeal and soy is unrealistic, noting that “the cost for using soy and fish meal comes in the environmental impact.” Crépieux ended his conversation with POLITICO on a grim note. “Everything sustainable always loses. It’s always easier to take from nature, which is free,” Crépieux said.
