This podcast episode (Nicole Johnsey Burke, May 29, 2025) argues that buying mass‑market/mailed ladybugs is ineffective and potentially harmful, and instead explains how to attract and sustain native ladybug populations by creating the right habitat. Key claims: commercially sold ladybugs are often harvested from high‑elevation western U.S. hibernation sites and shipped long distances (causing rapid dispersal); gardeners should provide three things—food, places to raise young, and overwintering shelter—to host all life stages (eggs, larvae, pupae, adults). Practical recommendations include planting dill/flowering cilantro/parsley/fennel (carrot family), cosmos, marigolds, yarrow, and alyssum; leaving some plants/pests (aphids) so larvae have food; avoiding insecticides (including neem oil) and synthetic fertilizers that deter ladybugs; and leaving stems/seedheads for winter shelter. Notable numeric claims from the host: adult ladybugs eat ~50 aphids/day (up to ~5,000/season); a larva can eat up to ~400 aphids before maturing.
