  • lacewings & ladybugs for whitefly

    Created by Dean on

    Can you release both the lacewings and ladybugs at the same time for whitefly control in a hobby (200 sq ft) greenhouse in Colorado?

    Dean –

    Yes that would work! Ladybugs move in quickly and will consume many of the immature stages and then, in many cases, move on. Lacewing tend to stick around a bit longer providing long-term control. I’ve provided a link below.

    You may also want to consider Encarsia formosa. These tiny parasitic wasps are the most cost effective biological control agent to control greenhouse whiteflies.

    Hope this helps!
