    Hello Allen –

    Neem oil acts as an insect growth regulator and is mildly toxic to trichogramma wasps. Also, it has been shown to have no adverse effects on the development of the parasitoid inside pest eggs. However, because neem applications deter oviposition — parasitization — we feel that it should be avoided when releasing the tiny wasps.

    Note: Azadirachtin, a major component of neem oil, breaks down quickly in the environment and should not persist for longer than 3-7 days.

    Hope this helps!
