What's eating my dionaea muscipula 'cupped trap'?
Aphids
Signs: Dense colonies on petioles and around trap rims; sticky honeydew residue; stunted growth
Control: Remove manually with tweezers or rinse with distilled water; submerge plant in distilled water for 24–48 hours to drown colonies
Fungus gnats
Signs: Larvae damage rhizome in waterlogged sphagnum; adults are the early visible warning sign
Control: Use BTi drench (Bacillus thuringiensis israelensis); add yellow sticky traps near the tray; avoid standing water deeper than 1 cm

Control: Increase ambient humidity; rinse foliage with distilled water regularly; isolate the plant to prevent spread to nearby carnivores
