Venus Flytrap Deformed Traps and White Specks: Likely Aphids, Mealybugs, or Caterpillars

Venus flytrap with damage

Probable Culprits

Aphids, mealybugs, or whitefly — cause deformed traps, blackening new growth, white specks.
Caterpillar damage — chewed trap edges visible in photo.

Safe Treatment

Use carnivorous-plant-safe insecticides. Systemic options like acephate or imidacloprid (Bayer Rose & Flower) work well. Avoid insecticidal soaps—they break down into fertilizer-like compounds that harm sensitive plants (especially sundews and butterworts).
