Discoid Roaches vs Dubia: The Florida-Legal Feeder Every Keeper Should Know
If you've spent any time in Florida's reptile world, you've heard it: "You can't use dubia roaches here." It's true - Blaptica dubia are banned in Florida. That leaves a lot of keepers wondering what the best legal feeder alternative is. The answer isn't some obscure workaround. It's the discoid roach (Blaberus discoidalis) - and it's not just legal, it's genuinely one of the best feeders out there. Here's the full comparison.
The Florida dubia ban: what the FWC says
Dubia roaches are classified as a conditional species under Florida Fish and Wildlife Conservation Commission (FWC) rules. Florida law prohibits importing, selling, possessing, or breeding them without a special permit - and those permits aren't issued to pet owners or feeder sellers.
The reasoning is straightforward: Florida's subtropical climate means escaped dubia could survive and establish outdoor populations. The state has already been devastated by invasive species - Burmese pythons, Cuban tree frogs, cane toads - so the FWC takes a precautionary stance on any non-native organism that could establish in the wild. Penalties can include confiscation and fines; enforcement varies by county, but the legal risk is real and entirely avoidable.
Discoid roaches are exempt because they're native or naturalized to the Caribbean and southern Florida region. No permit is needed to buy, sell, breed, or keep them in any U.S. state.
Nutrition: near-identical
This is the comparison most keepers care about first, and the answer is reassuring - the two species are almost the same at the feeding bowl:
| Nutrient | Discoid | Dubia |
|---|---|---|
| Protein | ~20% | ~23% |
| Fat | ~7% | ~7% |
| Moisture | ~65% | ~61% |
| Fiber (chitin) | ~3% | ~3% |
| Calcium (mg/100g) | ~20 | ~20 |
| Phosphorus (mg/100g) | ~26 | ~27 |
| Ca:P ratio | ~0.77:1 | ~0.74:1 |
Dubia have a slight edge in raw protein; discoids carry a bit more moisture, which helps reptile hydration. Everything else is virtually identical. Note that both are phosphorus-heavy (that inverted Ca:P ratio), so dust either one with calcium before feeding - neither is a calcium source on its own. The nutritional difference between the two species is statistically insignificant.
Behavior: the same great feeder traits
Both species share the qualities that make feeder roaches so much better than crickets:
| Behavior | Discoid | Dubia |
|---|---|---|
| Climbs smooth surfaces? | No | No |
| Can fly? | No (males flutter only) | No (males flutter only) |
| Noise | Silent | Silent |
| Smell | Virtually none | Virtually none |
| Escape risk | Near zero | Near zero |
| Bite risk | None | None |
| Activity level | Slightly more active | Slightly calmer |
The only meaningful difference: discoids tend to be a touch more active and faster-moving, which some keepers find triggers a stronger feeding response - the extra movement catches a reptile's eye. Dubia are marginally calmer to handle during colony maintenance. Neither difference affects feeding outcomes.
Breeding speed
If you plan to breed your own colony, reproductive rate matters:
- Dubia reproduce faster - about 20-40 nymphs per litter with a 28-35 day gestation at optimal temperatures, so a colony becomes self-sustaining relatively quickly.
- Discoids are slower - roughly 25-35 nymphs per litter with about a 60-day gestation, so building a productive colony takes more patience.
Both are ovoviviparous (live birth), need similar breeding temperatures (85-95°F), and have similar care. Dubia's faster turnover gives breeders an edge - but that advantage is meaningless if you live somewhere dubia are illegal. And for keepers who buy feeders rather than breed them, reproductive rate is irrelevant.
Cost
Pricing is generally comparable at similar sizes from reputable breeders. Discoids can run slightly more in some markets because their slower reproduction means breeders produce fewer per cycle - though that gap has narrowed as discoid production scaled up nationwide.
The real cost consideration isn't price per roach - it's legal risk. In Florida, possessing dubia means risking confiscation and fines. There's no per-roach price that makes that worthwhile when a legally identical, nutritionally equivalent option exists.
Why you haven't heard more about discoids
Discoids were simply overshadowed early - dubia took the spotlight first. But discoids match them on shape and size range, don't climb or fly, are odorless and clean when raised well, are naturally high in moisture and protein, gut-load easily, and are legal in all 50 states. They're not just an alternative - in many cases they're a straight upgrade.
Great for these animals
Discoids are a staple feeder for a wide range of pets: bearded dragons, blue tongue skinks, ackie and savannah monitors, leopard and (adult) crested geckos, chameleons, tarantulas, and amphibians like pacman and tree frogs. They're even gaining ground with exotic-mammal owners looking for enrichment feeders.
Bottom line
Don't think of discoids as a backup plan for dubia - think of them as the Florida-approved upgrade. They're clean, quiet, nutritious, escape-proof, and legal everywhere. Whether you're a first-time keeper, a serious breeder, or running a shop, discoids deliver all the benefits of a feeder roach without the legal baggage.
