Your geraniums (Pelargoniums) are leggy, leaves dying from edges upward, tops wrinkled and bubbling. You sprayed insecticide, but pests aren't the issue. Here's the fix:
Geraniums must be cut back sharply in late winter/early spring to force bushy growth. Cut every stem to 3–4 inches above soil, just above a node. It looks brutal, but they'll rebound fast in increasing light.
"Wrinkled, bubbled, brown edges" suggests overwatering, poor drainage, or root rot—not insects. Insecticide was unnecessary and may stress the plant further. Email a photo if unsure.
If pots are old, repot in fresh, well-draining mix. Give maximum sun (south window). Water only when top inch is dry.
Prune hard, root cuttings, fix the culture—your geraniums will be compact and flowering by summer.
