Gladiolus Pest Management: Aphids, Ants, and Leaf Damage Control

Ants + "Fly Eggs" on Glads = Aphid Farm. Here's the Treatment.

The ants aren't the problem—they're farming aphids for honeydew. The "fly eggs" are aphid nymphs. The leaf chewing? Could be caterpillars or thrips.

Aphid Control (Primary Issue)

1. Blast: Strong water jet daily × 3 days. Knocks off aphids, washes honeydew.
2. Soap: Insecticidal soap (Safer's, etc.) every 3-5 days × 2 weeks. Cover undersides.
3. Pyrethrin: If severe, 2 applications 5 days apart. Last resort.

Ant Management

• Control aphids → ants leave (no honeydew)
• Tanglefoot on stake bases blocks ant highways
• Borax bait stations AWAY from plants

Leaf Chewers

• Inspect at night with flashlight (caterpillars feed nocturnally)
• Hand-pick. Bt (Bacillus thuringiensis) for caterpillars.
• Thrips: silver streaks, distorted flowers. Spinosad if severe.

Prevention

• Space plants for air flow
• Water soil, not foliage
• Remove plant debris
• Rotate glad locations yearly

Start with water blasts today. Aphids reproduce fast—don't wait.
