White Flies

Could you please tell me how to get rid of white flies?

One of the ironies of gardening is that often some of the smallest pests can create the biggest nuisance. White flies are a prime example. They plague many of our favorite plants such as gardenias, angel’s trumpets and even tomatoes!

You can see the evidence of their damage in the lack of vigor in the plant and the sickly yellow discoloration of the leaves.

You can tell that you have white flies by doing a simple test. Just shake the foliage of the plant and if a cloud of white insects fly out then you’ve spotted the culprit. I was able to get this infestation of white flies under control with repeated applications of an insecticidal soap.

Now, for this to work best, you really need to soak the underside of the leaves and the top of the plant all the way down to the base. My second line of defense is to use sticky, white fly traps. They are basically adhesive strips that are yellow in color. The yellow color is attractive to white flies and other insects so they’re drawn to land on it, stick, and eventually die.

You can pick these up at your local garden center and they’re easy to install.
