Hibiscus is not a seedling and not a muture plant. It has had some heat stroke too. I have put it the shade in a cool part of garden with bag over tight so they don't infest other plants.

As we don't have any products in our range that are registered for this purpose, the best advice we can provide for control is to use a hand removal method. This is best done in the late afternoon when the beetles are not as fast moving. Get a bucket of soapy water handy place underneath the trees branches. Shake the branch to remove any of the beetles and drop them into the bucket of water. Once you have eliminated all the harlequin bugs, you might like to place your hibiscus back in a sunny spot which is where it would much prefer to be. To help your plant to recover, you might like to apply a Yates product called Yates Dynamic Lifter Liquid . It's certified for use in organic gardens, and contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth.
