Short answer: yes — for many insect-eating reptiles, Dubia roaches are one of the best staple feeders you can offer. They are meaty and protein-rich, easy for most pets to chase and eat, simple to gut-load, and far easier to live with than many other feeder insects. They are not magic, though. Like every feeder, Dubias still need to be the right size, gut-loaded, dusted appropriately, and fed as part of a varied diet.
This refreshed 2026 guide combines our original reptile-wide overview with the best bearded-dragon advice from our older “Quick Look” post, updates a few claims that were too absolute, and walks through the benefits, the limits, and how to feed Dubias well.
Why Dubia Roaches Are Good Feeders for Reptiles
A nutritious staple — with one important caveat
Dubias are valued because they are meaty, relatively soft-bodied for a roach, and rich in protein compared with many common feeders. That makes them useful for growing juveniles and for insect-eating adults that need satisfying prey. The caveat is calcium. Like most feeder insects, Dubias naturally contain more phosphorus than calcium. So do not rely on the roach alone for calcium. Gut-loading and dusting are what turn a good feeder into a well-rounded meal.
Easy to digest for many reptiles
Dubias have a favourable meat-to-shell balance for many reptiles, which is one reason keepers often find them easier to feed than harder, crunchier prey. Digestibility still depends on the individual animal, the size you offer, and whether temperatures and lighting are right for digestion. If your pet is gagging, regurgitating, straining, or not passing stool, stop guessing about feeders and talk to a reptile veterinarian.
Made for gut-loading
Whatever is in the feeder ends up in your pet. Dubias eat readily and will take roach chow plus safe fresh produce, which makes them especially easy to gut-load for 24–48 hours before feeding. That is the whole idea behind our guide to how to gut-load Dubia roaches: fill the roach with better food, then let your reptile eat the roach.
A size for almost every life stage
From small nymphs for babies to larger roaches for adults, Dubias grow through a useful range of sizes. That range is a big reason they work for bearded dragons at every stage — baby, juvenile, and adult — as well as for many geckos and other insect-eaters. At Dragon's Diet, Medium Dubias are 3/8"–1/2". Always judge a feeder against your own animal rather than age alone, using the eye-gap rule below and our Dubia roach size chart.
Movement that encourages hunting — without the chaos
Dubias move enough to get a reptile interested, but they are slower and less frantic than crickets. For a timid bearded dragon, that can make feeding time less startling. For a confident hunter, a smooth-sided feeding dish keeps the roaches in view so the chase stays fun instead of turning into a hide-and-seek game around the enclosure.
Dubia Roaches for Bearded Dragons
Bearded dragons are the pet most people have in mind when they ask about Dubias, and for good reason. In the wild, dragons eat a changing mix of insects and vegetation. In captivity, they rely entirely on you to build that balance. A healthy dragon diet is therefore never “just roaches.” Dubias can be an excellent insect staple, alongside appropriate greens and vegetables and a supplement routine that fits your dragon's age and UVB setup. Our complete bearded dragon diet plan puts the whole picture together.
- Babies and young juveniles: small, appropriately sized Dubias offered in controlled feeding sessions, with daily greens introduced from the start.
- Older juveniles: gradually larger roaches as the eye gap grows, while greens become a bigger share of the bowl.
- Adults: Dubias as one part of a varied insect rotation, with leafy greens and vegetables making up most of the diet.
Exact amounts vary with size, appetite, body condition, and your veterinarian's advice. Watch the animal in front of you, not just a chart.
When you are ready to try them, our live Dubia roaches are the product page this guide supports — pick the size from the chart first, then order.
Benefits for Keepers, Not Just Reptiles
- Quiet. No chirping.
- Low odour when kept clean. A dry, well-maintained bin should not smell strongly; odour usually means it needs cleaning or less moisture.
- Easy to contain. Dubias cannot climb smooth plastic or glass, jump, or truly fly. Adult males have wings and can flutter to soften a fall, but they are not flying around your house.
- They do not bite people or pets in the way some other feeders can, which makes tong-feeding and dish-feeding calmer.
- Long-lived and hardy. With basic food, hydration, and warmth, Dubias generally stay alive far longer than crickets, so less of your feeder budget dies in the bin.
- Unlikely to breed loose in a typical home. Dubias are tropical and need sustained warmth and humidity to reproduce. That does not mean “let them loose” — contain them carefully — but a single escape is unlikely to become an infestation.
- Simple basic care. Egg crate, chow, a safe hydration source, and regular tidying cover most of it. Our Dubia roach care guide covers housing for keeping or breeding.
Which Reptiles and Other Pets Can Eat Dubia Roaches?
- Lizards: bearded dragons, many chameleons, tegus, water dragons, collared lizards, anoles, and many skinks including blue-tongue skinks
- Geckos: leopard geckos, crested and gargoyle geckos (as an occasional insect offering alongside their prepared diet), African fat-tailed geckos, day geckos, and tokay geckos
- Frogs and toads: Pacman frogs, White's tree frogs, African bullfrogs, and fire-bellied toads, sized carefully
- Turtles: some omnivorous species such as box turtles, as part of a species-appropriate diet — not as a staple for primarily herbivorous turtles
- Arachnids: many tarantulas and scorpions
That list is a starting point, not a feeding prescription. Species, age, and health change what “appropriate” means. If your pet is very small, elderly, unwell, or a species you do not see discussed in a trusted care guide, check with a reptile or exotic veterinarian first.
Are There Downsides? Yes — Here Are the Honest Ones
- They still need preparation. An ungut-loaded, undusted Dubia is a missed opportunity.
- They can burrow and hide. Use a smooth-sided feeding dish or tong-feeding.
- Allergy is possible. Use tongs, wash your hands, consider gloves for bin cleaning, and talk to your doctor if you develop symptoms.
- Legal and shipping restrictions apply in some places. Check local rules and the shipping information on the product page before you order.
- Variety still matters. See our comparison of Dubia roaches vs. crickets.
- Cost and size mistakes. If you are between sizes, size down.
Choosing the Right Size: The Eye-Gap Rule
Use this simple rule every time: never offer a feeder wider than the space between your pet's eyes.
- Look at your pet head-on and estimate the distance between the eyes.
- Compare the roach's width — not just its length — to that gap. Dubias are broad and flat.
- When in doubt, choose the smaller size.
For reference, Dragon's Diet Medium Dubias are 3/8"–1/2". For the full table, use the Dubia roach size chart rather than guessing from age alone. Re-check every few weeks for growing juveniles.
Making Every Roach Count: Gut-Load, Dust, Store
Gut-load for 24–48 hours. Feed the roaches a quality roach chow plus safe fresh produce, with water crystals instead of an open water dish. Full step-by-step: how to gut-load Dubia roaches.
Dust right before feeding. Lightly coat the roaches with an appropriate calcium supplement immediately before serving. How often, and whether to use calcium with D3, depends on species, age, and UVB.
Store them simply. Keep Dubias in a ventilated, smooth-sided container with egg crate, dry chow in one spot and hydration in another. For longer keeping or breeding, follow our Dubia roach care guide.
Bottom Line
Are Dubia roaches good feeders for reptiles? For bearded dragons and many other insect-eating reptiles, yes — they are nutritious, manageable, and easy to prepare well. The formula is simple: right size, gut-loaded, dusted, and offered as part of a varied, species-appropriate diet.
If you want to put that into practice, you can order Dubia roaches online after checking the size chart — and if you are new to keeping them, bookmark the care and gut-loading guides above for the first week.
Are Dubia Roaches Good Feeders? FAQ
Are Dubia roaches good feeders for bearded dragons?
Yes. Dubia roaches are a nutritious, easy-to-manage staple feeder for many bearded dragons when they are the right size, gut-loaded, and dusted as part of a varied diet. Babies, juveniles, and adults can all eat Dubias — just match the roach to the space between your dragon's eyes.
Are Dubia roaches better than crickets?
They have some practical advantages: Dubias are quieter, easier to contain, slower-moving, and generally easier to keep alive between feedings. Crickets are more active and can suit pets that respond to faster prey. Many keepers use Dubias as a staple and rotate other feeders for variety.
Do Dubia roaches have enough calcium?
Like most feeder insects, Dubias contain more phosphorus than calcium, so they should not be relied on for calcium on their own. Gut-load them for 24–48 hours and dust them with an appropriate calcium supplement before feeding, following a schedule that fits your pet's age, species, and lighting.
What size Dubia roach should I feed?
Choose a roach no wider than the space between your pet's eyes, and size down if you are unsure. At Dragon's Diet, Medium Dubias are 3/8"–1/2". Our Dubia roach size chart gives size guidance by reptile and life stage.
Can Dubia roaches infest my house?
Dubias are a tropical roach that needs sustained warmth and humidity to breed, and they cannot climb smooth surfaces, jump, or truly fly. An escaped roach is therefore unlikely to start a breeding infestation in a typical home, but you should still contain them carefully and check local rules.
Which reptiles can eat Dubia roaches?
Many insect-eating lizards, geckos, frogs and toads, some turtles, tarantulas, and scorpions can eat appropriately sized Dubias. Suitability and portion size depend on the species, so check a species-specific care guide or ask a reptile veterinarian if you are unsure.
