I have Crepe Myrtles on both sides of my front porch entrance. During the summer, these are normally plagued by Japanese beetles feasting on their leaves. This year, however, there are almost no beetles.
My blessing turned to dismay when literally hordes of common houseflies are all over my Myrtles. They appear to be not only stripping the flowered buds, but the flowers are very pale pink, when normally vivid pink.
Anyone experiencing problems with Crepe Myrtles this year? Any advice for the hordes of flies? I've been swatting relatively few, compared to the vast numbers of them (flies).
I tried the soapy water this evening. Seems the flies are attracted to the sweet, excretions from the hard to see aphids on the leaves. On close examination, I can see the aphids moving with a squirt of the soapy water! Also, the flies didn't appreciate the water spray. I'm gonna repeat this several times. I have several of the sticky strips hanging very nearby, They seem to help. Thanks for all your help. I was fearing having to remove my Myrtles.

I also mix 1 tablespoon of liquid soap in a quart of water in a spray bottle. Spray for almost any insects in garden & flowers. Good luck.

You can get yellow sticky traps that will attract small insects and trap them. Or you can spray them with insecticidal soap, being sure to get the underside of the leaves. Good luck.
