Green Peach Aphids? Melon Aphids? This Wasp Has a Plan.

If you’ve already ID’d the culprit—green peach, melon, black bean, or lettuce aphids—then you don’t need another spray cycle. You need a predator that can find what you miss, and multiply while doing it.

Aphidius colemani is a specialist parasitoid wasp that targets small-bodied aphids. Each female injects one egg per aphid. Days later, you’ll start seeing swollen, tan-colored aphid mummies—evidence that the next generation is already working.

This isn’t passive prevention. It’s live, tactical suppression with zero residue and built-in reinforcement.

Aphidius colemani (Live Adult Wasps)

Specialist Biological Control for Green Peach, Melon, and Other Small Aphids

Each bottle contains live adult A. colemani wasps, ready to parasitize aphids as soon as they’re released. These wasps don't eat aphids. They use them to make more wasps.

Once established, they offer consistent, targeted pressure without sprays, re-entry windows, or chemical resistance.

Best For:

  • Green peach aphid (Myzus persicae)

  • Melon and cotton aphid (Aphis gossypii)

  • Black bean, lettuce, and apple aphids

  • High-turnover greenhouse or tent crops

  • Growers needing control with no surface impact or phytotoxicity

Note: A. colemani is not ideal for large-bodied aphids like Macrosiphum. For mixed infestations, pair with Aphidoletes aphidimyza or ladybugs.

What They Target

Aphid Species Controlled
Green peach aphid (Myzus persicae) Yes
Melon/cotton aphid (Aphis gossypii) Yes
Black bean aphid (Aphis fabae) Yes
Lettuce aphid (Nasonovia ribisnigri) Yes
Apple aphid (Aphis pomi) Yes
Other small-bodied aphids (40+ spp.) Yes
Large-bodied aphids (Macrosiphum, etc.) No – pair with other predators

How They Work

Step Timing
Female wasp lays egg in aphid On release
Egg hatches 3–5 days
Aphid turns into a tan mummy 5–10 days after parasitism
Adult wasp emerges ~14 days total
Population decline visible Within 7–10 days


Mummified aphids = it’s working. Releasing weekly = it keeps working.

How Much to Use

Setting Infestation Release Rate
Grow tent (2×4 ft) Light 5–10 wasps
Garden bed (100 sq ft) Moderate 10–50 wasps per 10 sq ft
Greenhouse or field crops Heavy 1,000–5,000 per acre


Repeat weekly for 2–3 weeks, or until suppression is clearly underway.

Environmental Conditions

  • Temperature: 64–81°F ideal

  • Humidity: Moderate to high preferred

  • Light exposure: Avoid direct sun on release—shade or canopy is best

  • Wind: Low airflow zones improve survival in field applications

Pro Tips

  • Start early. These work best before populations explode.

  • Don’t spray. Even soft sprays will kill your wasps.

  • Look for mummies. Tan, bloated aphids mean it’s working.

  • Reapply weekly if pest pressure is high or persistent.

  • Pair with Aphidoletes aphidimyza or ladybugs for mixed or large-bodied aphids.

  • If releasing outdoors, do so under plant cover and in early morning or evening.

Shipping & Storage

  • Ships overnight with live delivery guarantee

  • Use immediately on arrival

  • If needed, store at 39–46°F for up to 48 hours

  • Do not freeze or expose to heat or light

What You’ll Notice

  • A shift from active clusters to stalled colonies

  • The appearance of tan mummies in ~7 days

  • A drop in sticky residue and aphid excretion

  • Healthy new growth returning

  • No visible wasps (they’re small and focused)

You don’t need to see them. You’ll see the results.
