Last fall our household of two people invested in a small, 3-tiered, commercially-available wormery that came with all components (bedding, lime, worms). All seemed to be going well until we brought it inside to protect it from sub-zero (C) winter temperatures. It was at this point that a colony of what looked like white spider mites (the same size as, though far less active than, the red ones) exploded in the wormery and inhabited the inner lid and surface of the kitchen scraps. The mites appear to like warm damp conditions so we did our best to control them by keeping the wormery aerated and by physically removing the mites regularly, although these efforts had little effect. The worms still seemed to be 'healthy', but when draining the reservoir, I often found several dead worms in the liquid. Once outdoor temperatures turned mild enough, the wormery went back outside. At this point, the mite population decreased, but this was accompanied by a mass worm die-off resulting in failure of the wormery. We followed advice that came with the kit (not adding onion or too many acidic scraps; added newspaper to absorb water; added eggshells to keep the pH balanced; drained the reservoir regularly; kept temperature as stable as possible). Searching through wormery-related online forums resulted in no helpful advice.
Has anybody had a similar experience and knows why this might have happened?
