Adalia bipunctata larvae
Raised in our controlled-atmosphere rearing rooms, Adalia bipunctata ladybug larvae are renowned for their exceptional effectiveness against aphids.
They remain on the plants into which they have been introduced, rapidly controlling aphid colonies.
Their efficacy on a large number of aphid species makes them a versatile control solution, effective in gardens and green spaces as well as in market gardening, arboriculture and ornamental crops, in greenhouses, tunnels or open fields.
A single larva eats up to 600 aphids during its cycle

How to use larvae against aphids?
Pre-release preparation
For a good ladybug action:
- Be sure of the presence of aphids.
- Avoid all pesticide treatments for 3 weeks prior to release.
- Limit the number of ants on your plants.
Storage
Our recommendations for keeping ladybugs:
- Keep them cold, dark and draught-free (in the fridge or in cold storage at 5 or 6°C).
- Even in this situation, do not keep them for more than 3 days.
The release
A successful release guarantees good results:
- Release ladybugs at the end of the day or on overcast days.
- Introduce them directly onto attacked plants.
- Avoid treating plants with pesticides for the next 3 weeks.
Follow-up
Check that the ladybug larvae are working properly:
- Keep a close eye on aphid colonies and the general condition of the plant.
- You'll know that the number of larvae is sufficient if, after 1 to 2 weeks, the aphid colonies fade and the plant regains vigor.

Your questions
Can larvae be released before aphids appear (preventive control)?
No, because in the absence of aphids, the larvae die off quickly.
Should ants be prevented from climbing on the plant before release?
Strongly recommended: ants protect aphids and can reduce the effectiveness of larvae.
Will the larvae leave the treated plant?
No: they'll stay until they reach adulthood.
Will the adults from the larvae remain in the garden or in the crop?
Yes, if there are still aphids present.
Will the adults from the larvae return the following year?
It's hard to know, but if the environment is very diverse (hedges, flowers, refuges, etc.), ladybugs can settle in naturally and return every year.
Should larvae be released every year?
Not necessarily: if aphids are generally very present and cause significant damage, it's advisable to introduce larvae every year to balance out the situation.
Can adults be introduced at the same time as larvae?
Yes, and recommended when the infestation is already well established or the area to be treated is large.
Can larvae be introduced when infestation is high?
Yes, but 2 or 3 days before release, it is advisable to reduce aphid populations by spraying with water or using a gentle, non-toxic treatment for ladybugs and other beneficial insects (black soap, ....).
