Here is a White Fly on a Trumpet Vine in my garden. If the picture will enlarge, you can get a better view.
The Preying Mantis is a natural enemy to the white fly so if you see a Preying mantis in your garden, leave it be to do its job of eradicating your garden from White flies.
I have marigolds planted in the garden but they do not seem to be keeping the flies off my Trumpet Vine! Look at the white powdery mold growing on the stem.When I spot them, I usually just take my fingers and run them along the stem to remove the mold and fly. I also squash the fly in the process, that is, if it does not jump away. This particular type of white fly is a quick jumper. I am usually watering at the same time so as to remove the sticky mess from my fingers and the plant stem. Kind of gross but does the job without pesticides.
An Ivy plant on my front porch was infested with the little buggers also.
It looks as though powder has been poured onto wet stems. Can you spot the little liquid sucking culprit in this close up picture of the ivy leaf?
I welcome certain bugs into my garden such as the Lady bug but this WHITE FLY is one bug I do not welcome, In the Garden...
