Answer: Aphids can be control organically with products containing neem or insecticidal soap. It is important with all aphid-control products to direct sprays upward from beneath the leaves to contact the pests, which prefer to hide on the underside of leaves.
Always follow label instructions for pesticide mixing and application procedures. Also, check the plant carefully before spraying. Often you will find that ladybeetle adults and larvae, lacewings, and syrphid fly larvae are present in numbers sufficient to get the aphid under control. Parasitized aphids appear like tan, dry aphid skins and are another indication of beneficials at work. If beneficials are present in adequate numbers, it may be best to put off spraying to avoid damaging them. Also, make sure your hibiscus is getting everything it needs - correct sun exposure, moisture and air circulation. Overfeeding plants can make them more attractive to pest insects.
