A few weeks ago, Ann of SnapEditScrap posted her vase of Peonies and said they had so many ants on them she had to take them back outside. I told her a few drops of dish detergent in water and swish them around before bringing them in would remove the ants.
So Said Google-Girl!
I brought this flower in and dipped it in soapy water and all the ants were gone.
Down the drain in the sink to swim in the Muck.
The Hibiscus can lie on a dish, in a bowl, or stand in water.
It will dead the next day no matter which you do.
Enjoy the flowers while you may.
I think they look better on the bush, with the zillion little ants running around
