Chickens naturally eat insects, and dried black soldier fly larvae (BSFL) make a great high-protein and calcium treat.
These dried grubs (also called “fly grubs” or “chicken snacks”) are safe, sustainable, and full of nutrients. BSFL typically has 35-45% protein and 3-4% calcium.
This is much more calcium than mealworms. Gardens and homesteaders use BSFL as an “antimicrobial, gut-healthy superfood,” which they say strengthens eggshells and improves overall flock health.
Here in this article, we compare and review the top 11 dried BSFL products on Online USA (all 4-star+ rated), then provide a full buyer’s guide: nutrition facts, feeding tips, benefits for layers, chicks, molting hens, safety, and FAQs.
Dried black soldier fly larvae (BSFL) are a high-protein, high-calcium treat that chickens absolutely love. This guide includes our top picks with pros/cons, a comparison table, and answers to questions about feeding, nutrition, and safety so you can choose the best BSFL treat for your flock.

9. Fluker’s Culinary Coop Dried Soldier Worms (16 oz)
Fluker’s Culinary Coop is a familiar name in pet foods that also offers BSFL treats. The 16 oz pouch is much smaller than the others, but it is loaded with “essential nutrients,” as the label says.
It has protein, calcium, and even omega-3. “The percentages aren’t on the front, but we estimate protein at about 35-40% and calcium at about 4% (similar to the multiple of mealworms).
It can even be used by reptile owners, chickens, and ducks. We find this product very convenient for trying BSFL without buying large bags. Fluker’s is a Best Choice product with thousands of purchases, so you know the quality is proven.
The packaging is USDA compliant, and the brand name is known and trusted. We do note that it is expensive relative to weight. Still a nice introduction to BSFL, or a treat for smaller flocks.
Key Features:
- Pack of 16 oz (resealable pouch)
- Labeled “Packed with Protein and Calcium, Omega-3”
- High-quality brand (Fluker’s is known for reptile feed)

Cons: Small size (higher $/lb), less economical, Missing explicit macros on pouch
Our Verdict: Fluker’s is great for pet chicken owners who want a trusted, small-format treat. It won’t feed an army, but it works well for training or as a supplemental treat. The 4.8-star reviews show chickens like it. This is our pick for convenience and brand trust, even if you sacrifice some economy.
10. Hatortempt Dried BSFL (5 lb)—Organic Larvae
And last but not least, Hatortempt’s smaller 5 lb pack (same brand as #1). Nutrition is the same formula. 40% protein, 4% calcium. The benefit here is a smaller and cheaper size.
The larvae are the same as the 10 lb batch, hand- inspected and organic fed. For the flocks wanting quality from Hatortempt but can’t handle 10lb at a time, we mention it primarily.
The flavor and the company style are still enjoyed by chickens. The 5lb version is usually about half the price of the 10lb, which makes it a decent deal per pound. Great for a small coop or starting out.
Key Features:
- Same formula as Hatortempt 10 lb (40% protein, 4% Ca)
- 5lb box/pouch, zippable inside bag
- Organic-fed larvae, no GMO or hormones
- Easy portioning for small flocks
- Great intro product for newcomers
Pros: High protein/calcium, trusted Hatortempt brand, resealable box, ideal for small orders
Cons: 5 lb (limited quantity), price per pound is slightly higher, similar formulation to 10 lb
Our Verdict: If you liked Hatortempt’s quality but need a smaller bag, this is the one. You don’t lose any nutritional benefit compared to the 10 lbs. We recommend this for the first-time chicken keeper or as a gift to friends. Use it just like the 10 lb—a little goes a long way to boost egg and feather health.
Buyer’s Guide
What Are Black Soldier Fly Larvae (BSFL)?
Black soldier flies (Hermetia illucens) are beneficial insects whose larvae are often used as animal feed. Dried BSFL are nothing but the dehydrated larvae of these flies. They are preferred for fast breeders, can be grown on organic waste, and provide a rich source of nutrients for feed. BSFL gives your chickens the natural diet they would forage in the wild for insects and grubs in a convenient package. When dried, BSFL is a crunchy treat that has a long shelf life.
Why Chickens Love Them
Chickens love insects naturally—BSFL are meaty and have a mild, nutty flavor that’s irresistible. Larvae are rich and energy-dense due to their high fat content. Many chicken keepers say that poultry will eagerly eat BSFL even after refusing other treats. BSFL also contains lauric acid, which has natural antimicrobial properties that can support gut health. Chickens love BSFL, as it’s a nutritious, tasty treat that is similar to what they would eat in nature.
Nutritional Profile (per 100 g dry BSFL)
- Protein: ~40–45% – Very high compared to standard feed or mealworms. Essential for muscle growth and feathering.
- Fat: ~25–35% – A healthy fat that provides energy. Lauric acid (14-carbon fat) in BSFL is antimicrobial.
- Calcium: ~3–4% – Over 80× more than mealworms, critical for eggshell formation.
- Phosphorus: ~0.5–1% – Supports bone health (uncommon in insect feeds at high levels).
- Amino Acids: BSFL provides essential amino acids (lysine, methionine, etc.) crucial for growth. They are especially lauded for arginine and leucine content, aiding tissue repair.
BSFL has high digestibility and a balanced amino acid profile, which contribute to feather regrowth and muscle development. For instance, one study showed BSFL to contain all essential amino acids and be easily digested by poultry.
Benefits for Different Needs
- Laying Hens: BSFL’s calcium and protein can contribute to strengthening eggshells and increasing egg size. Laying hens require around 4g of calcium per day. One serving of BSFL doesn’t provide all of that, but every little helps to prevent thin shells. Good quality protein also helps to maintain peak layer and general condition.
- Growing Chicks: Chicks younger than ~3 weeks should not be fed large BSFL (may cause digestive upset) After 4-6 weeks, small amounts of powdered or ground BSFL can be useful for rapid growth. Once their crops are stronger, small dried grubs are a favorite of chicks. It’s starter-level protein.
- Feather-molting chickens: Hens require extra protein during the molt. This is ideal for BSFL (about 40% protein). It helps birds grow feathers back faster. It helps the immune system in stress.
- Free-Range Flocks Even free-range flocks can benefit from BSFL during the winter or lean season. A handful of dried larvae guarantees consistent nutrition (especially calcium when they can’t forage for insects).
- Winter Feeding: BSFL meals provide chickens with a taste of their natural diet when insects are scarce. The extra fat also gives calories for warmth.
- Training Treats: BSFL’s crunchy size and strong smell make them ideal for training (e.g. recall or behavior reinforcement). Most chickens will work gladly for a morsel of these grubs.
How to Feed:
Portion Size:
A general rule of thumb is about 20 grams (approx. 1/2 oz) per adult chicken per day (roughly 10-20 larvae depending on size). This can be given as a single treat or divided into morning and evening.
How often:
BSFL should be occasional treats and not the bulk of the diet. Mix with regular feed 2-3 times weekly or give as a free choice treat. Overfeeding any high-fat treat can cause dietary imbalance.
Mixing:
Sprinkle them on the ground, put them in a dish, or mix them in mash. Crushed dried larvae can also be sprinkled on the feed for added protein.
Watch Birds:
Aggressive birds may hog treats, so use feeders or split batches to prevent bullying.
Young Chicks:
Do not feed dried BSFL to chicks under ~3 weeks (their crop may be too small; wait till ~4 weeks and introduce gradually). If using, crush very fine or mix sparingly with starter.
Other Poultry:
Ducks, geese, and quail can all safely eat BSFL, but in portions relative to size (quail only a few grubs).
Feeding Chart (Example for 10 chickens, per feeding):
- Brood of Chicks (4+ weeks): 1–2 Tbsp total (crushed/dry larvae mixed in).
- Small Flock (5 chickens): 3–4 Tbsp of whole dried larvae, 2–3×/week.
- Medium Flock (10 chickens): 3/4 cup of dried larvae per day (mixed into feed or offered alone).
- Large Flock (20 chickens): 1.5 cups per day, or unlimited if self-fed in a treat dispenser.
Storage Tips and Shelf Life
Dried BSFL keep like dried mealworms. Store in an original sealed pouch or in an airtight container, away from moisture. Storing in a cool, dry pantry is fine; no refrigeration needed. Properly sealed, they can last 1-2 years (check packaging for best-by). Fats can oxidize over time, so if it smells stale/rancid, it’s time to replace it. Keep it from getting damp. Mold will kill the larvae.
Common Mistakes
- Overfeeding: Too much BSFL can cause birds to become fat or have a calcium/phosphorus imbalance. Treat quantities only.
- Feeding chicks too early: Don’t feed whole or dried insects to chicks until they are 4–6 weeks old. Too much protein given too early in very young chicks may cause choke or loose poop.
- Calcium Needs Ignored: BSFL doesn’t provide calcium, so keep on feeding your layers grit or oyster shell.
- Cross-Contamination: Always use clean utensils and bowls; dried larvae are shelf-stable, but once they get wet with saliva/poop, they can spoil.
- Not Mixing: BSFL should be kept in a tray or mixed with feed, not scattered everywhere (which can attract rodents) to avoid mess and pests.
When Not to Feed
- Day-old chicks (too rich).
- Already obese birds: Treats add calories; use sparingly if birds are overweight.
- Illness. If a hen is very weak or sick, plain feed is best until she comes back to her appetite again. (Some vets even recommend BSFL for convalescence, as they are highly digestible.)
- With Soft Tissue Medications: If treating birds with specific medicated feed, check whether the added protein and calcium levels could interact.
Mealworms vs. Black Soldier Fly Larvae
- Protein: Mealworms are ~50% protein, a bit more than BSFL’s ~40%.
- Fat: Mealworms ~25% fat vs. BSFL ~28% (BSFL have more fat).
- Calcium: BSFL contains a lot more calcium (~3-4%) than mealworms (~0.07%). This improves BSFL for eggshell support.
- Amino Acids: Both are good, but BSFL has more lauric acid (antimicrobial).
- Cost & Sustainability: Mealworms are readily available but need to be fed with grain. They are raised on waste and have a lower carbon footprint.
- Chicken Preference: Not all chickens like BSFL, but many flocks prefer the crunch. Both can add variety to the diet.
Organic vs. Conventional BSFL
Some brands (Hatortempt, Joyprotyn) mention larvae fed on organic waste or produce. Others just say “sustainably farmed.” Practically all dried BSFL are free of pesticide residues because the larvae do not uptake anything from the food (they convert waste into biomass). The main difference is whether the brand’s feedstock is organically certified. This is primarily a marketing point. For backyard use, the nutritional differences are not relevant. What matters most is purity (no filler), and all of the suggested products are pure.
Whole vs. Crushed Larvae
Most products are made from whole dried larvae, which the chickens naturally crack open and eat. Crushing is optional; it allows dusting their feed but can reduce palatability and make a mess. Larvae as a whole promote foraging behavior. Unless you are disguising them in feed for picky eaters, we recommend giving the whole BSFL to allow chickens to peck them.
Fresh vs. Dried Larvae
Many feed producers use fresh (live or frozen) BSFL, but dried larvae are far more convenient for backyard hobbyists. Dried larvae are easier to store and have a long shelf life. Drying does not significantly degrade protein or calcium, so dried BSFL are just as nutritious in terms of nutrient content. Dried BSFL is best for everyday feeding. (Live larvae are preferable for BSF farm growth, not required for chickens.)
Identifying High-Quality BSFL Products
- Ingredients: Must be 100% black soldier fly larvae. No additives. No fillers. No herbs.
- Packaging: Resealable bag or pouch is ideal. Thick, food-safe material keeps them fresh.
- Odor and Cleanliness: BSFL should smell neutral, a little sweet. Any musty or rancid odor indicates spoilage. Dust (fine powder) and debris should be absent from the product.
- Certifications: Some brands test for both pathogens and heavy metals. Trusted companies may use the wording “USDA inspected” or similar.
- Brand Reputation: Check out popular poultry feed brands or pet treat companies with positive reviews. Look for the “Best Choice” or “Best Seller labels.
- Storage Advice: The company should advise storing it in a cool, dry place. Quality dried insects can be stored for up to two years.
Avoiding Low-Quality Products
Beware of:
- Low-priced bulk “worm” bags: These sometimes contain mealworms, silkworms, or fillers instead of 100% BSFL.
- No ingredient label: If the product doesn’t clearly say “black soldier fly larvae,” skip it.
- Expired or Moist Packages: Any clumping or mold means it’s gone bad.
- Suspiciously low prices: Very cheap options may have poor production standards or be selling off last year’s stock (check date).
- Vendor Information: Only buy from sellers with clear contact info or high seller ratings to ensure you get fresh product.
The Science Behind BSFL Feeding
- Calcium and Eggshells: Laying hens need over 4 g of calcium in their daily diet and use roughly 2.2 g of calcium per egg. Thin shells are caused by lack of calcium. Convenient calcium supplement. The addition of BSFL has been shown to improve shell quality.
- Protein Requirements: Laying hens need ~16-18% protein, more if molting or growing. Broilers require ~22%. BSFL, ~40% protein, is a good supplement. Research shows BSFL protein is highly digestible, rich in essential amino acids, and beneficial for feather and muscle development.
- Natural Diet: Chickens naturally forage for insects, and BSFL mimics this behavior. Studies from universities indicate that feeding live or dried larvae does not impact on bird health or meat quality. In fact, eating insects can be good for your gut health. Insect protein can be used efficiently by poultry, a review in Poultry Science says.
- Immune Support: Lauric acid from BSFL is antimicrobial. One study found that BSFL larvae reduce harmful bacteria (like Salmonella) in feed substrates. So feeding BSFL may help control pathogens in the coop environment.
- Bone Health: The phosphorus and fat are also good for bone mineralization. Birds that are fed BSFL tend to have stronger bones during molt and fewer broken bones.
- Molting & Immunity: BSFL’s protein levels allow for new feather synthesis during the molting process. Micronutrients and lauric acid can also help improve immune response, which can come in handy when hens are vulnerable in cold/flu seasons.
- Sustainability Note: Not directly nutritional, but many studies tout BSFL as an eco-friendly feed ingredient (they can be fed on waste and have low water use), which goes hand-in-hand with sustainable poultry farming best practices.
Safety Tips
- Feeding to Chicks: Do not feed dried BSFL to chicks under ~4 weeks. Their crops (storage pouch) and kidneys are not ready for high protein/calcium. Wait until about 6 weeks for the whole grubs, or mash very small amounts into chick starter if needed.
- Feeding to Other Poultry: Ducks, turkeys, and quail can eat BSFL with similar benefits. Give quail tiny portions (they eat fewer grubs).
- Avoid Overfeeding: Too many treats can lead to obesity or fatty liver disease. Treats (including BSFL) should make up no more than ~5–10% of the diet.
- Storage Safety: Always keep BSFL sealed. Old, rancid larvae can cause digestive upset. If larvae ever smell rotten, throw them out. During warm weather, store in the freezer (unopened) to prevent fat oxidation.
- Mold & Rancidity: Rare in dried BSFL if stored well, but if moisture gets in the bag, throw it away. Moldy insects can kill chickens.
- Pests: Dried larvae can attract mice or rats if spilled. Feed in the coop or use a sealed treat dispenser. Clean up leftovers promptly.
- Allergies: Poultry handlers with insect allergies should use gloves. Though dried, BSFL can still cause reactions if you handle it a lot.
Frequently Asked Questions
Q: Are black soldier fly larvae better than mealworms for chickens?
A: Both BSFL and mealworms have their benefits. Mealworms have slightly higher protein (~50% vs. ~40%), but BSFL have much more calcium (3–4% vs. ~0.07%). For layers needing calcium, BSFLs are usually better. Nutrient-wise, BSFL also contains beneficial fats and lauric acid. Many keepers feed a mix of both for a varied diet.
Q: Can chickens eat too many BSFLs?
A: Yeah. And overfeeding any high-fat treat can cause overweight chickens. Too much calcium can also affect other minerals. Offer small portions (see chart above) a few times a week, not at every meal.
Q: How many larvae should chickens eat daily?
A: A common guideline is around 20 grams (~10-15 medium larvae) per adult hen per day if used as a supplement. Change with flock size: More birds = more total, but the per-chicken amount is similar. Very young chicks get crumbs, not whole grubs.
Q: Can baby chicks eat dried larvae?
A: Very young chicks (under 4 weeks) should not be fed whole dried larvae. Their digestive systems aren’t prepared. You can start with tiny crumbles (~2-3% of the diet) at ~4 weeks or wait till ~6 weeks for whole pieces.
A: Yes, generally. Calcium in BSFL (in particular) and protein can improve egg size and shell strength over time. BSFL aren’t a miracle fix, but many keepers report more consistent egg-laying and fewer cracked shells after adding them. The added protein also helps keep hens in better body condition for laying.
Q: Are BSFL high in calcium?
A: Yes. Dried BSFL have several percent calcium (about 80 to 100 times more than mealworms). This makes them a great natural source of calcium, particularly for laying hens. But you should still provide oyster shell or grit for the full calcium requirement.
Q: Can BSFL replace chicken feed?
A: Nope. BSFL is a treat/supplement, not a full feed. They contain no carbs and some vitamins. They are a source of protein and calcium, but you will still need a balanced poultry feed for overall nutrition. Think of BSFL more as a vitamin-packed snack than a staple chow.
Q: Are dried larvae safe if they look old?
A: Look for musty or sour smells, which indicates rancidity or mold. If they smell funky or are sticky/damp, toss them. Dried larvae should be hard and odorless when properly stored. Always buy products before their shelf life (most have a 1-2 year expiration.)
Q: Can ducks or turkeys eat BSFL?
Q: Yeah. Ducks love BSFL, especially, and the nutrient profile is good for waterfowl as well. Turkeys and quail can also eat these safely (quail only in tiny amounts). Treat these species the same way—use BSFL as an occasional protein-rich supplement in their diet.
Q: How should dried BSFL be stored?
A: Store in a cool dark place (pantry or cupboard) and keep the lid tight. Store in a cool place. Once opened, reseal tightly or transfer to an airtight container. Shelf-stable, but heat or humidity can shorten their life. Unopened bags can be frozen for long-term storage.
Q: Do BSFL attract rodents?
A: Any dried pet food left sitting out can attract rodents. To avoid this, feed BSFL in the coop or in a container inaccessible to rodents and clean up any spills. Otherwise, BSFL are a dry product and are no more uniquely susceptible to pest issues than any other dry feed.
Q: How long do dried larvae last?
A: Most manufacturers guarantee a shelf life of 1-2 years. They will remain edible for that length of time if kept properly (sealed, cool, and dry). Protein and fat content may deteriorate after the date. The safest course is to buy what you will use within a year.
Final Verdict
Premium chicken treats and dried black soldier fly larvae provide natural appeal and superior nutrition. Hatortempt (10 lb) was a standout for quality and value for large flocks from our reviews.
Joyprotyn and Adaman were top for protein/calcium content. Sansect and I Love Worms gave excellent boosts of calcium in forms that were easy to feed, and the lesser-known Larvevo was high in protein in a neat package. All of the recommended products have high ratings and positive reviews from coop keepers.
All these BSFL goodies are actually good for your hens. For layers, prefer high-calcium varieties (Adaman, SANSECT). Protein – Buntie, Larvevo, for broiler or active flock. For budget picks, WormsFarm and I Love Worms offer big bags at good prices.
If you’re a beginner, Fluker’s or Hatortempt 5 lb are gentle introductions (small size, no overwhelm). Just make sure they’re fresh and you give the right amount.
With the information in this guide, you’ll be able to confidently select an online-available BSFL product that meets your flock’s needs. Whatever you choose, remember: these larvae are meant as a supplement—feed responsibly and enjoy healthier, happier chickens.
