Small Holes in Venus Flytrap Traps: Prey Fighting Back

Beetles and Caterpillars Chew Their Way Out

Tiny holes on traps that have caught insects are usually exit wounds from:

• Weevils, stink bugs, cucumber beetles – hard‑bodied, plant‑eating insects.
• Caterpillars (like the “worm” you found) – soft‑bodied but persistent.

The trap reopens after digestion; the holes are from the prey’s escape attempts.

Treatment for Caterpillars

• Bacillus thuringiensis (BT) spray – organic, specific, bee‑safe.
• Systemic imidacloprid (Bayer) – only if not in bloom.

Monitor; if damage is minor, no treatment needed. The plant catches the pests, after all.
