Worm harvesting apparatus and method for recovering worms from their accompanying habitat soil, utilizing worm gathering projections, on the interior of a drum rotatable about a substantially horizontal axis, to gather worms from accompanying soil disposed in the lower portion of the drum as such soil cascades upon itself during drum rotation and in turn to carry such worms to the upper portion of the drum for gravity release thereat from such projections to permit gravity deposition of the worms in a collecting receptacle disposed in the drum.
