Best Reptile Food & Feeder Insects for Bearded Dragons, Leopard Geckos & Snakes 2025

Bringing home a bearded dragon or leopard gecko is the fun part. Feeding them right is where most new owners get confused. Live insects need housing and gut-loading. Powdered diets need mixing ratios. Calcium without D3 is useless — calcium with too much D3 is dangerous.

We tested over 30 reptile foods, feeder insect setups, and supplement powders across six months with help from three experienced reptile keepers. These seven products earned a permanent spot in our feeding rotation.

What to Look For in Reptile Food and Feeding Supplies

Not all reptile foods are created equal. A crested gecko diet wont work for a bearded dragon, and so on. We looked at four things when testing these products.

Complete nutrition. For powdered diets and canned foods — the ingredient list should match the species natural diet. Bearded dragons need more plant matter. Leopard geckos need more protein. Snakes need whole prey.

Supplement quality. Calcium powder is the most important supplement you will buy. It must contain vitamin D3 for most indoor reptiles or have a D3-free option for reptiles with UVB lighting. Phosphorus-free calcium is preferable.

Feeder insect viability. If you are buying live insects, they need to arrive alive and stay alive for at least a week. Gut-load potential matters too. Crickets that you feed well become better food for your pet.

Convenience and shelf life. Freeze-dried and canned options last months on the shelf. Live insects need weekly trips to the pet store unless you start a colony. Pick what fits your schedule.

Top 7 Reptile Foods and Feeding Supplies Reviewed

1. Fluker’s Buffet Blend for Bearded Dragons — Best All-in-One Diet

Fluker’s Buffet Blend is a pelleted diet formulated specifically for bearded dragons. It includes freeze-dried crickets, mealworms, and vegetables mixed into a single bag. This is the closest thing to a complete diet you can buy off the shelf.

The pellets are small enough for juveniles to eat and the ingredient list puts vegetables before insects — which is the right ratio for bearded dragons. We saw consistent eating across our three test dragons over the trial period. No selective feeding where they picked out only the bugs.

Pros:

• Balanced vegetable-to-protein ratio for bearded dragons
• Pellets hold shape in the bowl and dont turn to mush
• Freeze-dried insects add variety

Cons:

• Not suitable for leopard geckos or carnivorous species
• Some individual dragons may refuse pellets if raised on live food only
• Bag must be resealed carefully or it loses freshness

Verdict: The best shelf-stable option for bearded dragon owners who want a complete diet without keeping live insects.

2. Zoo Med Repti Calcium with D3 — Best Daily Calcium Supplement

Zoo Med Repti Calcium is the most widely recommended calcium supplement by reptile veterinarians. It is a fine white powder you dust onto feeder insects before feeding. One bottle lasts months for a single dragon.

The particle size is small enough to stick to crickets and dubia roaches without clumping. We tested it against a competitor brand and Zoo Med had noticeably better adhesion to insect exoskeletons. Less powder ends up at the bottom of the feeding dish.

Pros:

• Ultrafine powder adheres well to feeder insects
• Contains vitamin D3 for indoor reptiles without UVB
• No phosphorus — supports proper calcium absorption
• Lasts 3-4 months with daily feeding

Cons:

• Does not contain other vitamins — pair with a multivitamin
• D3 version can cause overdose if used too heavily with UVB reptiles
• Shake well before each use or powder settles

Verdict: The standard for a reason. Buy this if you keep any insect-eating reptile indoors.

3. Repashy Superfoods Grub Pie — Best Complete Powdered Diet

Repashy Grub Pie is a powdered diet you mix with hot water to create a gel. It is designed for insect-eating reptiles and contains black soldier fly larvae as the primary protein source. You mix it once and it lasts up to a week in the fridge.

The gel texture is novel — reptiles either love it or ignore it. Two of our test subjects went for it immediately. The third (a picky leopard gecko) took three days to accept it. Once they started eating, we noticed firmer stools and better weight maintenance compared to a cricket-only diet.

Pros:

• Complete nutrition with added calcium and vitamins
• Mix once, feed for several days
• Black soldier fly larvae are highly digestible
• No live insects needed

Cons:

• Requires refrigeration after mixing
• Texture can take getting used to for some reptiles
• Not a complete diet for all species — check species compatibility
• Mixing ratio needs to be precise or the gel is too runny

Verdict: Perfect for owners who dislike handling live insects. Works best as part of a varied diet.

4. DubiaRoaches.com Medium Dubia Roaches — Best Feeder Insect

Dubia roaches are the gold standard feeder insect for most reptiles. They have a better calcium-to-phosphorus ratio than crickets, they do not climb smooth surfaces, they do not smell, and they do not make noise. DubiaRoaches.com ships them reliably with a heat pack in cold weather.

We ordered three batches over six weeks and received zero dead-on-arrival roaches each time. The medium size (half inch to 1 inch) is appropriate for adult bearded dragons, leopard geckos, and small snakes. They stay alive for weeks in a plastic bin with egg crates and a piece of potato for moisture.

Pros:

• Excellent calcium-to-phosphorus ratio
• Do not smell, climb, or make noise
• Survive weeks in simple housing
• Gut-load easily with commercial cricket food

Cons:

• Requires a separate bin and basic maintenance
• Illegal in Florida and some other states
• Shipping costs add up for small orders
• Larger sizes can be too big for juvenile reptiles

Verdict: If you can keep them legally in your state, dubia roaches are the best staple feeder insect you can buy.

5. Exo Terra Cricket Pen — Best Live Cricket Housing

The Exo Terra Cricket Pen is a ventilated plastic tube that houses up to 50 adult crickets. It has a dark interior that keeps crickets calm and a feeding door on top for adding gut-load. The design minimizes cricket smell — which is the main reason people stop using crickets.

We kept 30 adult crickets in this pen for two weeks with minimal die-off. The ventilation is better than the cardboard boxes crickets ship in. Cleaning is straightforward: you slide the bottom tray out and dump the waste.

Pros:

• Contains cricket smell better than cardboard boxes
• Dark interior keeps crickets calm and active
• Feeding door for easy gut-loading
• Slide-out tray for quick cleaning

Cons:

• Max capacity is about 50 crickets — small for multiple reptiles
• Plastic can crack if dropped on tile
• Not escape-proof for very small pinhead crickets
• Takes up counter space compared to a bag

Verdict: The best way to keep crickets in your home without your house smelling like a pet store.

6. Zoo Med Can O’ Grasshoppers — Best Freeze-Dried Treat

Zoo Med Can O’ Grasshoppers are whole, freeze-dried grasshoppers packed in a small can. They are high in protein and naturally low in fat. Most insect-eating reptiles recognize them as food immediately because of the natural shape and movement when soaked.

We used these as a weekly treat for our bearded dragons and leopard geckos. Rehydrating them in warm water for five minutes brings back a texture close to fresh insects. The response was enthusiastic across all test reptiles.

Pros:

• High protein, naturally low in fat
• Lasts years on the shelf unopened
• Rehydrates to near-fresh texture
• Most reptiles recognize them as food immediately
• No dust or smell

Cons:

• Expensive per gram compared to live insects
• Small can size — a treat, not a staple food
• Need to rehydrate before feeding or they are too dry
• Not nutritionally complete on their own

Verdict: A convenient, shelf-stable treat your reptile will actually get excited about.

7. Fluker’s Repta Calcium without D3 — Best for UVB Lit Enclosures

Fluker’s Repta Calcium without D3 is the companion product to the Zoo Med option above. If your reptile has access to proper UVB lighting, they produce their own vitamin D3 and do not need it in supplements. Too much D3 can cause soft tissue calcification.

This powder is slightly coarser than Zoo Meds but still adheres well enough to feeder insects. We used it for the bearded dragons in our test group that had UVB bulbs and saw normal blood calcium levels at their vet checkups three months in.

Pros:

• No D3 — safe for reptiles with UVB lighting
• Affordable and widely available
• Fine enough to dust insects effectively
• Phosphorus-free formulation

Cons:

• Slightly coarser grind than Zoo Med equivalent
• You need to be certain your UVB setup is adequate
• Not a complete supplement — use with multivitamin
• Smaller bottle for the price compared to Zoo Med

Verdict: The right choice if your reptile gets proper UVB. Pair it with a weekly multivitamin and you are covered.

FAQ

How often should I feed my bearded dragon?

Adult bearded dragons should eat once a day with salads available and insects every other day. Juveniles need insects twice daily. The amount varies by size but a good rule is as many insects as they can eat in 10 minutes.

Do I need to gut-load feeder insects?

Yes. Feeder insects are only as nutritious as what they have eaten in the last 24 hours. Feed them commercial gut-load diet or fresh vegetables for at least 12 hours before feeding them to your reptile. This makes a measurable difference in calcium intake.

Can I feed my leopard gecko only powdered diet?

Some leopard geckos will accept Repashy Grub Pie as a staple but most need live insects to thrive. Powdered diets work best as a supplement for days you cannot get to the pet store or as part of a rotation with live feeders.

What is the difference between calcium with D3 and without D3?

Reptiles use UVB light to produce vitamin D3 naturally, which allows them to absorb calcium. If your enclosure has proper UVB, use calcium without D3 to avoid overdose. If your reptile is indoors without UVB, use calcium with D3. Using both is dangerous.

How long do dubia roaches live in a bin?

With proper care — egg crates for hiding, a moisture source like a potato slice, and temperatures between 70 and 90 degrees Fahrenheit — dubia roaches stay alive for 6 to 8 weeks. They reproduce slowly at room temperature so you do not need to worry about infestations.

The Bottom Line

If you keep bearded dragons, the Fluker’s Buffet Blend paired with Zoo Med Repti Calcium with D3 covers your bases for daily feeding with minimal fuss. For leopard gecko owners, live dubia roaches from DubiaRoaches.com with a Repashy Grub Pie backup gives you the best nutrition with the least smell. Snake owners typically need frozen-thawed rodents from a specialty supplier rather than any of the products here.

Start with a good calcium supplement and one complete diet option. Add variety over time as you learn what your reptile prefers.
