Berkley Gulp! Earthworm

Yes, unlike traditional soft plastics made from PVC, the Berkley Gulp! Earthworms are manufactured from a proprietary, water-soluble, and biodegradable polymer. This means the bait will naturally break down in the water if lost, reducing environmental pollution. Berkley specifically designed the material to release heavy scents rapidly while maintaining this eco-friendly profile.

These soft baits are primarily marketed for catching panfish like bluegill and crappie, as well as largemouth and smallmouth bass. The natural earthworm profile and heavy scent dispersion mimic real forage, making them highly effective for trout as well. Anglers frequently rig them on small jig heads or drop-shot rigs to target suspended fish.

Because the biodegradable material is softer and more brittle than standard plastic worms, they cannot be rigged Texas-style as effectively without tearing. Instead, they are best fished on a small jig head, a drop-shot hook, or wacky rigged. Anglers must be careful when casting, as aggressive strikes can easily shred the delicate material.

The powerful scent dispersion relies on the water-soluble polymer remaining highly hydrated, so baits must be kept in their original Gulp! liquid brine. If a Gulp! Earthworm dries out completely in the sun or open air, it will harden permanently and lose its biodegradable scent-release properties. Keeping the jar tightly sealed ensures the baits remain soft and effective.
