  • aphids on milkweed

    Created by Fred Laird on May 12, 2015 at 9:05 am

    Hello –

    We raise Monarch butterflies and have a major outbreak this year of aphids on our milkweed crop. Does your soap manage the aphids without affecting the eggs and caterpillars of the Monarch.

    Thanks,
    Your response will be appreciated.

    Insecticidal soap works via dehydration and is short lived in the environment. However, it is not specific to aphids. If you could spot treat the aphid colonies, rather than blanket spraying, you would minimize any damage to the monarch butterflies, larvae and eggs. In fact, once insecticidal soap dries it is no longer effective. I’ve included a link to our Aphid Control page.

    Hope it helps!
