What’s A Good Insect Spray for Hibiscus?
The short answer to this question is a spray with a strong stream of water to blast the pests off the plant.

Let’s look at why these are the best general-use pest control sprays.
Why Are Insecticidal Soaps and Neem Oil Sprays The Best?
Both neem oil and insecticide soaps will help control these Hibiscus plant pests.
The oils in these soap sprays cover these soft-bodied insects and suffocate or “bleed” them out.
Where Can You Buy Neem Oil or Soap Sprays?
Most lawn and garden centers carry insecticide soap and neem oil sprays.
Always look at the bottle and verify that the spray is safe for hibiscus plants or ornamentals.
Stay away from using liquid Malathion sprays on Hibiscus as the oil is too thick.
What About Homemade Sprays for a Hibiscus plant?
Homemade pest remedies like insecticidal soap have become popular alternatives with organic gardeners. Many companies are producing organic options and providing gardeners with DIY recipes.
Neem oil is an excellent option for hibiscus pest control. It’s made from oil derived from the seeds of the neem tree.
Neem is best used for the management of aphids, whiteflies, mealybugs, and thrips. All these pests dine on the plant juices of the hibiscus.

What Organic Spray Could I Use?
It is pretty clear that an organic option is the best, but some gardeners reach for a chemical spray.
NOTE: A spray may state it will kill a pest; that does not mean it’s good for your Hibiscus or the environment.
As mentioned, Hibiscus lovers should avoid using Malathion. The oil is too thick and causes foliage to burn.
