Green lacewing larvae are what you reach for when the aphids are already there. They ship as incubated eggs, timed to hatch about 24 hours after they arrive — so instead of waiting on a fresh egg stage, you get larvae right at the point they emerge hungry and start hunting. The nickname "aphid lion" is earned: aphids are what these larvae are built to clear, and they'll work leaf by leaf through an active population. They'll opportunistically pick at other soft-bodied pests they bump into — thrips, mealybug crawlers, spider mites, whitefly — but don't buy them for those. They're not a reliable treatment for anything but aphids; for the others you want the specialist. This is the pick for active aphid outbreaks and hot spots on high-value plants — when you want the problem handled now, not weeks out. Common Name: Green Lacewing Larvae (aphid lions) Target: Aphids. That's the job. Other soft-bodied pests may get eaten incidentally, but lacewing larvae are not a dependable treatment for thrips, mealybug crawlers, spider mites, or whitefly — use the specialist for those. Format: Incubated eggs in a protective carrier material, timed to hatch about 24 hours after delivery. Best For: Curative treatment of active aphid outbreaks and hot-spot cleanup on high-value plants. Key Advantage: Timed to hatch on arrival. The eggs are pre-incubated, so larvae emerge and start feeding about a day in — no long wait for a fresh egg stage.
