Why Pet Makers Are Switching to Insect Protein

Walk into any independent pet supply shop in Austin or Portland right now and you’ll notice something odd on the shelves: kibble bags with pictures of black soldier fly larvae on the front, positioned right next to the salmon and chicken options. A year ago, those bags were tucked in the corner near the raw food freezers — almost apologetically. Today, they’re at eye level. That shift didn’t happen by accident.

Here’s the thing most coverage of this trend gets wrong: the story isn’t really about sustainability, even though that’s what everyone leads with. The real driver is something far more practical — allergy management. A growing number of pet owners have dogs and cats with protein sensitivities, and they’ve burned through beef, chicken, lamb, even venison. Insect protein is what’s called a “novel protein,” meaning most pets’ immune systems have never encountered it before, which makes it genuinely useful for elimination diets. The eco-angle is real, but it’s not what’s moving product off shelves week after week. Itchy dogs are.

1. The Numbers That Convinced Skeptical Buyers

Industry analysts tracking the alternative protein pet food segment have reported consistent double-digit growth over the past three years, with some estimates putting the global insect-based pet food market on track to surpass $1.5 billion USD by the late 2020s. That’s not a niche anymore. Major pet food trade shows — the kind held in Chicago and Atlanta every year — started dedicating full exhibit halls to insect protein brands around 2023. By 2025, several regional grocery chains had started stocking at least one insect-based option alongside conventional premium lines.

What changed? Two things happened almost simultaneously. First, regulatory clarity improved in the US — the Association of American Feed Control Officials (AAFCO) updated its ingredient definitions to formally recognize certain insect meal sources, which gave manufacturers a cleaner path to labeling compliance. That matters enormously when you’re trying to get a product into Petco or PetSmart. Second, the cost of black soldier fly larvae meal dropped as production scaled up, narrowing the price gap between insect-based formulas and mid-range chicken-based kibble. Not closed — insect protein still commands a premium — but narrow enough that a segment of pet owners started actually buying it rather than just reading about it.

2. What’s Actually in the Bag: A Quick Breakdown

Most commercial insect-based pet foods use one of three primary sources: black soldier fly larvae (Hermetia illucens), mealworms (Tenebrio molitor), or crickets (Acheta domesticus). Black soldier fly larvae dominate the market right now, mostly because they’re efficient to raise — they can be fed organic waste streams, which keeps production costs lower — and they have a favorable amino acid profile for dogs. The crude protein content in dried black soldier fly larvae meal typically runs between 37% and 45%, which is competitive with chicken meal.

For cats, the picture is more complicated. Cats are obligate carnivores with specific amino acid requirements — taurine being the big one — and early insect-based formulations struggled here. Brands that cracked the cat market generally did it by supplementing insect protein with additional taurine rather than relying on the insect meal to carry the full nutritional load. Some still haven’t gotten the cat formula right, which is why you’ll see far more insect-based dog food on shelves than cat food, at least for now.

3. A Real Transition: What One Small Brand’s First Year Looked Like

A small pet food startup based in Colorado — one I’ve followed since they were selling at farmers’ markets out of coolers — launched their first insect-based dog kibble line in early 2024. They used black soldier fly larvae as the primary protein, sourced from a domestic farm in North Carolina. The first batch sold out in six weeks, mostly to people who’d already tried everything else for their allergic dogs. But the second production run sat longer. Why? Two reasons, both instructive.

One: the bag design led with the sustainability message. “Better for the planet.” Pet owners who were buying for allergy management felt like the product wasn’t speaking to them — they didn’t care about the planet angle in that moment, they cared about their dog stopping to chew its paws at 2 a.m. The brand redesigned the packaging to lead with “novel protein for sensitive dogs” and sales picked back up. Two: the price point — around $72 for a 20-pound bag — created sticker shock when people could find chicken-based limited ingredient diets for $45. The brand introduced a smaller trial size at $22, and that became their best-selling SKU. Not because people were cheap, but because they wanted to test their dog’s response before committing.

The lesson here isn’t that insect protein is a tough sell. It’s that the messaging has to match the actual problem the buyer is trying to solve. And sometimes the buyer needs a smaller first step.

4. What’s Not Working — And Why

I’ll be direct here, because there’s a lot of wishful thinking floating around in the insect protein pet food space.

• Leading with the gross-out rebuttal doesn’t work. Brands that spend the first half of their website convincing you that insects aren’t disgusting are losing. Buyers who are already open to insect protein don’t need the pep talk, and buyers who aren’t won’t be converted by a listicle about how crickets are eaten in Thailand. Lead with the problem you solve.
• Positioning as a premium lifestyle product misses the real buyer. Some brands have gone heavy on the “artisanal, small-batch, sustainable” angle — beautiful photography, muted earth tones, the whole thing. That attracts a buyer who will switch to the next trendy ingredient in eighteen months. The stickiest customers are the ones with allergic pets. They’re loyal because the product actually works for their animal, not because it aligns with their values.
• Ignoring veterinary channels is a real mistake. Veterinary dermatologists and internists are the ones sending clients on elimination diet journeys. Brands that have no vet outreach, no sample programs, no presence at veterinary continuing education events — they’re leaving the most motivated buyers on the table. A vet who recommends insect protein for a patient with food allergies creates a customer who will buy that product for the next ten years.
• Expecting the cat market to mirror the dog market is premature. The formulation challenges are real. Launching a cat food before the nutritional profile is dialed in — and then getting a bad review on a pet nutrition forum because a cat lost weight on the food — can crater a brand’s reputation in a tight community faster than almost anything else.

5. The Supply Chain Reality Most Brands Don’t Talk About

Here’s a part of the insect protein story that gets glossed over in the breathless coverage: domestic insect farming at scale is still young, and supply chains are fragile. A temperature spike at a production facility can wipe out a larval population. One supplier going offline can leave a pet food company scrambling for ingredient substitutes mid-production run — which creates labeling headaches and potential regulatory issues if a substitute ingredient wasn’t already approved in the formula.

Brands that are building real resilience are doing a few specific things: contracting with multiple farms rather than relying on a single supplier, maintaining a buffer inventory of dried meal (which has a shelf life of roughly 12 months when stored correctly), and investing in supplier relationships early rather than treating insect farms like commodity vendors. The companies that approached insect protein as just another ingredient swap — plug it in, run the numbers, move on — have had rougher experiences than those that got deeply embedded with their farming partners.

There’s also a geographic dimension. The US insect farming industry is concentrated in a handful of states, and transportation adds cost and complexity. Some brands have made the strategic decision to co-locate their manufacturing close to their insect farm supplier, which adds logistical constraints but reduces supply chain risk. It’s not the most exciting part of the story, but it’s where a lot of the competitive advantage actually lives.

6. Where the Big Players Are — and Why They’re Moving Slowly

The major multinational pet food companies have been watching this space carefully. A few have made quiet acquisitions of smaller insect-based brands rather than developing in-house. Others have filed ingredient patents and formulation trademarks that suggest active R&D without public product launches. The hesitation isn’t lack of interest — it’s risk calculus. A brand that sells hundreds of millions of dollars in chicken-based kibble every year isn’t going to disrupt its own supply chain and retailer relationships without clear evidence that insect protein can scale without margin erosion.

What would accelerate their move? Two things: a sustained period of chicken or beef price volatility that makes insect protein look cost-competitive across larger volumes, and a major study — from a veterinary university, a government agency, or a well-regarded independent research body — demonstrating long-term health outcomes for dogs on insect-based diets. The anecdotal evidence from pet owners is strong. The peer-reviewed long-term data is still thin. Filling that gap is probably the single most important thing the insect protein industry could invest in right now.

7. The Consumer Who’s Actually Buying This Stuff

From what I’ve observed at pet expos, in online communities, and in conversations with independent pet store owners, the current buyer breaks into roughly three groups. First, the allergy-management buyer — described above, highly motivated, not particularly price-sensitive once they find something that works. Second, the environmentally conscious buyer who is already buying sustainable products across categories and sees insect protein as consistent with that worldview. Third — and this one surprises people — the raw feeding community, a subset of which has started incorporating dried insect-based toppers and treats as a complement to raw meat diets, partly for the amino acid diversity and partly because insect-based treats are shelf-stable in a way that raw isn’t.

That third group is interesting because they’re not the obvious target, but they’re vocal advocates online, and in the pet world, online advocacy — a detailed post in a breed-specific Facebook group, a thread on a raw feeding subreddit — still drives meaningful purchase behavior. A handful of insect protein brands have figured this out and are quietly sending samples to influential community members in these spaces. It’s old-school influencer marketing, but it works when the product is genuinely solving a problem.

Start Here This Week

If you’re in the pet food industry — whether you’re a buyer at a regional chain, a formulator at a startup, or a veterinarian fielding allergy questions — three small moves are worth doing before anything else.

First: Get a sample of at least two commercially available insect-based pet foods and actually read the ingredient panel and guaranteed analysis side by side with a comparable conventional limited-ingredient diet. The differences are more instructive than any white paper.

Second: Spend thirty minutes in a pet allergy or food sensitivity forum — there are active ones on Reddit and Facebook — reading what pet owners say when they talk about switching to novel proteins. You’ll hear the real objections, the real wins, and the real confusion faster than any focus group will tell you.

Third: If you’re a vet or vet tech, ask your next food allergy case whether they’ve heard of insect protein as a novel protein option. The answer will tell you exactly how much education still needs to happen — and where you can actually add value.

The shelf space is shifting. The question is whether the industry moves deliberately or just reacts when the space gets crowded.
