Aphidius ervi | Large Bodied Aphid Control
Target Pests
Pea aphids, potato aphids, lettuce aphids, rose aphids, and other large-bodied aphid species.
Product Description
Despite looking like tiny delicate flies, these parasitic wasps are aphid-hunting specialists. They seek out and lay eggs inside larger aphids and turning them into golden "mummies." Hatching begins within 5 days of receiving mummies. Release adults right away once they emerge. If you are not sure which type of aphids are present, try Aphid Double Mix or Aphid Triple Mix for broader spectrum aphid control.
Note: activity may slow during short day lengths (fall/winter), as this species can go dormant.
Introduction Rates
Release 1–5 insects per 10 sq. ft., weekly, for 2–3 weeks
Temperature range: 50–86°F
Rates are general guidelines. Actual needs vary by pest species, plant, and infestation level. Monitor both pests and released insects to gauge success.
Application
Sprinkle gently onto affected plants (never directly on soil). Leave the container open on its side for 24 hours so stragglers can emerge. Keep contents dry and undisturbed for a few days.
Pro Tips
- Remove yellow sticky traps for the first few days so you don't accidentally catch your new allies.
- Try our Hanging Release Boxes to concentrate wasps on infested areas while keeping them dry and mess-free.
- Look for round-holed golden mummies on leaves within 10–14 days. This is a sign the predators are working.
