With the oleander’s beauty and low maintenance comes an occasional caterpillar. Do not let caterpillars deter you from using oleanders in your landscape.
There is an easy cure for caterpillars sometimes found in oleanders.
At the first sign of a caterpillar (have to move quickly as their damage can come on suddenly,) simply apply Seven Dust onto the oleanders. Seven Dust comes in either powder or liquid form; follow directions on the package.
It may take a couple treatments, but you should be caterpillar free in no time.
