Catalpa Worm Farming: Trees First, Then Eggs—Not Incubators

You Can’t Hatch Catalpa Worms in an Incubator

Catalpa worms (catawba worms) are caterpillars of the catalpa sphinx moth. They require fresh catalpa leaves daily—no artificial diet works.

Real‑World Approach

1. Your 210 trees are the foundation.
2. Collect egg masses from wild trees with prior infestations (Feb–Mar).
3. Attach to your trees; caterpillars emerge and feed.
4. Harvest mature caterpillars for bait.
5. Freeze excess for off‑season sales.

Moth Source

No reliable commercial moth/egg suppliers. Network with bait shops, local anglers, or extension agents to find wild egg sources.
