An adult female Aphidius matricariae can infect up to 300 aphid prey in her life time. This parasitic wasp lays her eggs inside live aphid nymph prey. The eggs incubate in their unsuspecting hosts and hatch as ravenous larvae who eat their victim from the inside. Eventually the host aphid will die and mummify. The wasp then use the mummified aphid as a place to pupate eventually emerging as a winged adult ready to start the cycle over.

Dosage - The information given here is a general guideline. Release rates can be affected by the stage/size of the cannabis plant, climate conditions, and level of infestation.

For preventative applications use 0.25 A. matricariae per ft², repeating weekly. For small infestations use 1 wasp per ft² repeating weekly for a minimum of three weeks or until biological balance is achieved. For large infestations use 2 wasps per ft², repeating weekly for a minimum of 6 weeks or until biological balance is achieved.


Release Method

Your Aphidius matricariae will arrive packaged in plastic bottles with mummies being mixed with a sawdust carrier. Carefully remove the lid and gently transfer bottle contents to beneficial distribution boxes (recommended if in flower) or directly onto the leaves of the plants. For preventative applications distribute your A. matricariae evenly throughout your crop. For infestation applications place the wasp mummies near aphid hotspots.




We recommend releasing the mummies upon receipt.

If immediate release is not possible keep your A. matricariae in a dark place with a temperature of 6-8°c and relative humidity of 85% until the expiry date on the package.
