Pest control on hibiscus or any plant or garden must be done with utmost consideration to safety; safety in terms of the plants, animals and humans. This holds especially true for those with vegetable and organic gardens. The main purpose of growing vegetables organically will be defeated if they become tainted with pest control chemicals.

Here are a few long-term maintenance tips to make pest control less damaging and more environmentally friendly.

1. Use the physical control process.

2.  Apply biological pest control.

Encourage predatory insects such as green lacewings and dragonflies to feed on aphids and other pests that attack your plants. You can do this by placing a shallow bowl of water in the garden. Dragonflies especially will hover around water. Bacterial insecticides such as B. thuringiensis could also be used against caterpillars.

3. Only as a last resort should we turn to chemical pest control.

Organic pest control methods can be successful and the ingredients for many of the recipes can be found in the kitchen cupboards. If chemical sprays are really necessary, try and find the least-toxic. These include horticultural oils, dehydrating dusts, etc.

4.  Know the good from the bad bugs.

Most garden insects do more good than harm. Butterflies, beetles and bees are known pollinators. They fertilize plants through unintentional transfer of pollen from one plant to another. 80% of flowering plants rely on insects for survival.

Sowbugs and dung beetles together with fungi, bacteria and other microorganisms are necessary to help in the decomposition of dead plant material, thus enriching the soil and making more nutrients available to growing plants.

Other insects like lacewings and dragonflies are natural predators of those insects that do the real damage, like aphids.

5. Consider the use of safer pest control substitutes.Recipes for alternative pest control include the following:

Against Green Aphids and Mites - Mix 1 tablespoon of liquid soap and a cup of vegetable oil. Dilute a teaspoon of this solution in a cup of water and spray on aphids and mites.

Against Cockroaches - Dusts of boric acid can be applied to cracks or entry points of these insects. Bay leaves on pantry shelves could also help in warding off these critters.
