At Logee’s, we have turned our attention to using beneficial insects, or known in the industry as IPM (integrated pest management). Today’s post is about treating for Western Flower Thrip. Western Flower Thrip is a prevalent pest in most garden centers and seen on outdoor plants. We recently had an outbreak in our new 19,000 sq. foot production greenhouse and this is what we did.
The home gardener can treat thrip, spider mite and white fly with predatory pests. I’m one of those gardeners that like convenience. For the past three years I’ve treated all my indoor plants with predatory insects and after two applications each year, I easily solve the problem.

The bugs for the home gardener come in tubes. Simply sprinkle the bugs, packing material and all on your indoor plant’s leaves. The bedding or sand-like substance in the tube is what carries the beneficials. It looks like sand on your leaves but is necessary so the beneficial insects can crawl out of their packing material and onto the leaves to find and consume the bad bugs.
Keep in mind, that these bugs are microscopic, only stay on the plants, will not crawl around in your house or on the furniture and in my opinion is easier than spraying. After several weeks, wipe off the sand-like material.
