Can Bearded Dragons Eat Discoid Roaches?
Yes, discoid roaches are an excellent staple feeder for bearded dragons and a Florida-legal alternative to dubia. Learn nutrition, sizing, and feeding.
Discoid roaches are one of the best staple feeders available for bearded dragons, offering high protein, low fat, easy digestion, and a calcium-to-phosphorus ratio that beats crickets. They cannot climb smooth surfaces or fly, so they are simple to contain, and they are the standard staple roach for keepers in Florida where dubia roaches are restricted.
The verdict: Excellent staple. Yes, feed discoid roaches freely. They are high in protein, low in fat, easy to digest, and have a better calcium-to-phosphorus ratio than crickets. They cannot climb glass or fly, and they are Florida-legal where dubia are not.

Discoid roach nutrition for bearded dragons
Discoid roaches, sometimes called false death's head roaches, are a soft-bodied feeder that is high in protein and low in fat. Their exoskeleton is thinner and easier to digest than that of many hard-shelled insects, so their chitin load is manageable. Most importantly, their calcium-to-phosphorus ratio is far more favorable than crickets, which makes balancing the diet easier.
Like the closely related dubia roach, discoids are an ideal staple. They are quiet, do not smell strongly, do not bite your dragon, and are simple to keep because they cannot climb smooth surfaces. They still need a light calcium dusting for growing dragons, but they start from a much better mineral baseline than crickets or mealworms.
| Factor | Discoid roaches |
|---|---|
| Protein | High |
| Fat | Low |
| Chitin | Moderate, thinner shell, digestible |
| Ca:P ratio | Better than crickets, lightly dust |
| Best role | Everyday staple insect |
Why discoids are easy to keep
One reason discoid roaches are so popular is how manageable they are as a colony. They cannot climb smooth glass or plastic and they do not fly well, so a smooth-sided bin keeps them contained with no risk of household infestation. They need warmth and humidity to breed, conditions that do not occur in a typical home, so escapees do not spread. They are also legal in Florida, unlike dubia roaches, which is why many Florida keepers rely on them.
How to feed discoid roaches
- Size each roach no longer than the space between your dragon's eyes.
- Gut load the roaches on greens and vegetables before feeding.
- Lightly dust with calcium for growing dragons on your normal schedule.
- Offer them in a dish or release a few at a time, since they move more slowly than crickets.
- Keep your colony in a smooth-sided, ventilated, warm bin.
How often to feed discoid roaches by life stage
- Hatchlings and babies (0 to 5 months): small nymphs offered several times a day, eaten freely in short sessions.
- Juveniles (5 to 18 months): a frequent staple once or twice a day as greens grow in the diet.
- Adults (18 months and up): a handful a few times a week within an insect rotation, alongside a diet that is roughly 80 percent greens.
Risks to watch for
- Sizing: respect the eye-gap rule even with soft roaches to avoid impaction.
- Over-reliance: even a top staple should be part of a varied rotation.
- Colony care: a poorly kept colony produces less nutritious feeders, so keep them fed and warm.
A balanced bearded dragon diet is roughly 80 percent insects for babies and 80 percent leafy greens for adults. Discoid roaches are one of the very best insects to build that protein portion around, especially for Florida keepers.

Frequently Asked Questions
Are discoid roaches good for bearded dragons?
Yes, discoid roaches are an excellent staple feeder. They are high in protein, low in fat, soft enough to digest easily, and have a far better calcium-to-phosphorus ratio than crickets. They cannot climb smooth surfaces or fly, which makes them easy to contain. For keepers in Florida, where dubia roaches are restricted, discoids are the go-to staple roach.
What is the difference between discoid and dubia roaches?
Both are excellent staple feeders with very similar nutrition and a favorable calcium-to-phosphorus ratio. The main practical difference is legality: dubia roaches are banned in Florida, while discoid roaches are legal there and are the standard staple roach for Florida keepers. Discoids grow a bit larger and are sometimes called false death's head roaches. For feeding purposes, you can use them interchangeably.
Can discoid roaches infest my house?
It is very unlikely. Discoid roaches cannot climb smooth vertical surfaces like glass or plastic and do not fly well, so escapees struggle to spread. They also need warmth and humidity to breed and do not thrive in typical home conditions the way pest roaches do. Kept in a smooth-sided bin, a discoid colony stays contained and will not become a household pest.
What size discoid roach should I feed?
Use the space between your dragon's eyes as your maximum size guide. Discoid roaches come in many sizes from tiny nymphs to large adults, so you can match them precisely to your dragon. Small nymphs suit babies and juveniles, while adult dragons can take larger roaches. As always, when in doubt, choose the smaller size to avoid impaction.
Do discoid roaches still need calcium dusting?
Discoid roaches have a better calcium-to-phosphorus ratio than crickets, but they still tilt slightly toward phosphorus, so dusting growing dragons with calcium is still recommended. You will not need to dust as heavily as with poorer feeders. Continue including calcium with D3 and a multivitamin on the schedule that fits your UVB lamp and your dragon's age.
How many discoid roaches can a bearded dragon eat?
Because they are lean and nutritious, discoid roaches can form the backbone of the insect diet. Babies and juveniles can eat appropriately sized roaches in frequent short sessions, while adults take a handful a few times a week. Their healthy profile makes them one of the easier feeders to use generously without the fat worries of treat insects.
