Silkworms vs Dubia Roaches: Which Feeder Is Better?
Silkworms vs Dubia Roaches: Supplement vs Staple
Silkworms and dubia roaches (or their legal equivalent, discoid roaches) are both premium feeder insects — but they serve fundamentally different roles. Roaches are the daily protein staple. Silkworms are the premium low-fat supplement. Understanding this distinction means using each feeder for what it does best.
| Category | Silkworms | Discoid/Dubia Roaches |
|---|---|---|
| Primary role | Low-fat supplement | Daily protein staple |
| Protein | 9% | 20-23% |
| Fat | 1% | 7% |
| Moisture | 83% | 65% |
| Chitin | None | Moderate |
| Gut-loadable? | No (eats only mulberry) | Excellent |
| Shelf life | 1-2 weeks (needs food) | Weeks-months (minimal care) |
| Serrapeptase | Yes | No |
Not an Either/Or Decision
This comparison is not about choosing one over the other — it is about understanding that they serve different functions in the same feeding rotation. Roaches provide the protein foundation that fuels daily activity and growth. Silkworms provide the low-fat premium supplement that prevents obesity, supports hydration, and delivers the unique serrapeptase enzyme.
A reptile eating only roaches misses the ultra-low-fat nutrition and serrapeptase that silkworms provide. A reptile eating only silkworms gets insufficient protein for muscle growth and maintenance. Together, they complement each other perfectly.
The Complete Rotation
- Daily: Discoid roaches (protein — 20%, gut-loaded, calcium-dusted)
- 2-3x/week: Silkworms (1% fat, 83% moisture, serrapeptase, zero chitin)
- 1-2x/week: BSFL (9,340 mg/kg calcium — no dusting)
- 1-2x/week: Hornworms (85% moisture, 3:1 calcium, appetite stimulation)
Note: Dubia roaches are banned in Florida. Discoid roaches are the legal equivalent with nearly identical nutrition — legal in all 50 states.
