Twisted Dionaea Leaves and Ant Infestation: Copper Wire Toxicity and Bait Solutions

Twist ?

Dionaea

Gabriel (non-native English) asked about twisted leaves on a large Dionaea in terrarium (14h light, 88% humidity, 79–90°F day/68°F night). Used copper wire to stake leaves. Wants to kill ants everywhere.

Copper Wire = Toxic

Jacob Farin (covering for Jeff): Copper is toxic to all plants. If staked into soil, it's the likely cause of decline. Plant may recover if root damage isn't severe.

Dormancy Factor

Some D. binata forms (dichotoma, T-form) need winter rest. Without it, they lose spring vigor.

Ant Control

Bait stations (e.g., Terro liquid baits). Ants farm aphids—treat aphids too.

Follow-Up: Bayer Product Test

Bayer

Gabriel bought a Bayer product (pyrethrins + sulfur). Jacob: Should be fine—avoid insecticidal soaps. Test on one plant 2 days before full application. Unlisted wetting agents can cause issues.

Good Growing!
