Ants do not lay eggs on plants, and contrary to popular belief ants are more beneficial then not since they help clean up our environment. They are liking the area where the fruit dlowers are growing because that is where they food source is. Look closely to see what it is they are feeding on and then you can take the steps necessary to control that which will then control the ants.

Perhaps the "eggs" are instead aphids. If so, squish them or hose them off.

I have a similar problem. Just took pics and video...the best i could. I first noticed the leaves falling off my vinca plants. Upon closer instpection I saw lots of ants in the good part of the plants. Some were sitting stationary on the leaves and then I saw some carrying a white egg or semi clear embryo looking thing. Then I saw a leaf with a winged ant and it appeared to lay a bunch of these and then the ant scurried away from them. The ants sitting still appear to be sucking something from the leaves and then the leaf falls off. Any ideas. Again I have pics and video. New here so not sure how to share yet. I might post this as a new thread as well.

Here is a pic. The little white things look like white imature ants. But I suppose they could be anything. I would like to note that I do not see these white things anywhere else on the pland where the ants are not present. I think I see them taking the white things down into a hole in this potted plant. Next I will see if I can find a way to post the video on YouTube and send you a link.

Here is a pic of the leaf where I saw the winged ant and assumed that was the one laying the eggs. The video makes it look like that is what happened anyway.

Here is a link to a video of the winged one.
