We would like to live in a world without suffering, no war or disease or..... insect pests! However, our beautiful and lush hibiscus make tempting targets for several insects who have no regard for what they do to the plants. These insects pierce the leaves and suck the sap out of them, sometimes spreading plant viruses as they feed. Or they lay their eggs in the flower buds, make the buds fall off before opening. Or, after sucking plant sap, the insects excrete the remains all over the leaves, making an unsightly mess. Or....well, you get the idea. These insects are referred to as pests, and pests they can truly be!
Fortunately, we have a number of ways to deal with insect pests. The links at the bottom of this page contain detailed information about the various insect pests that are found on hibiscus and how to control them. We say "control" because you can never eliminate any pest entirely. Even if you eliminate the pests completely from your own hibiscus, they are everywhere in the world around us. Our goal is to control them by limiting their numbers to the level where they do no visible harm and do not multiply out of control.
Control techniques include both chemical and non-chemical approaches. Chemical approaches can be organic (these pesticides are safer for humans and the environment but still require common sense precautions) or synthetic (this includes the pesticides made in the lab that are usually more effective but require following directions so as not to be harmful to the applicator). Non-chemical approaches are also referred to as organic, and do not involve any type of pesticide.
It can be difficult to decide which pest control approach to use. Should you use the most effective means (usually synthetic pesticides) immediately when noticing a problem? Or should you start with the safest but most labor-intensive approach first and check out the results before bringing out the "big guns?" The answer can depend on your own situation. If you are ill or especially sensitive to environmental factors, you probably want to stay away from synthetic pesticides. If you are healthy but very busy and don't have much time or patience to deal with pests, then by all means use the most effective products available. If you are an "organic-only" person, we have suggestions that do work, but may take persistence.
White Flies

Pest control starts with noticing that there is a problem. Obtaining a magnifier of some sort helps with seeing these often very small creatures. Some are easily seen, such as white flies and aphids. Others, such as thrips and spider mites, are more difficult to see. Often the pests are not noticed until visible damage appears, by which time the pests are out of control and need to be stopped immediately! Mottled yellow leaves that are rapidly increasing in number are one such visible sign that requires immediate attention. Lack of flowers despite lots of small buds forming (and then falling off before they open) is another visible sign. Fine webbing at the tips of stems, or black sticky deposits on the tops of leaves are other signs of insects that require attention.
