Pyrethrum is by far the most effective natural insecticide and miticide there is and kills most aphids, cabbage loopers, celery leaf tiers, codling moth, Colarado potato beetles, leafhoppers, Mexican bean beetles, spider mites, stink bugs, several species of thrips, tomato pinworms, and whiteflies, flies, gnats, mosquitoes and midgies.
As soon as insects come into contact with the spray, they will die, attacking the nervous system. Pyrethrum is an African flowering plant from the chrysanthemum family and is deadly to most insects. However, because it is not systemic and is destroyed by UV light, it is not deadly to mammals and can be safely sprayed on vegetables and fruit when picked 12-48 hours after application. Unfortunately, it is also deadly to good bugs as well, so use with care and only spray on heavily infested plants as a last resort.
Spray both the upper and lower surfaces of the leaves, because spray must directly contact the insects such as thrips that hide in leaf sheaths and crevices. Spray in cooler temperatures as it is more effective then, evening or late afternoon being ideal. Never use pyrethrin products around waterways and ponds. And for those of you who have dermatitis, asthma and sinus you may have an allergic reaction when using pyrethrum.
Grow your own pyrethrum from seed, which can be bought from your local seedman and use the flowers that are in full bloom. The active ingredient is found in the immature seed. Cut them off early in the morning and hang upside down to dry and leave in a well-ventilated dark place to dry. Light will cause the plant to lose its potency. When dried, grind with a pestle and mortar until you have a fine powder.
Mix 10 gm of pyrethrum powder to 3 litres of water. Let stand for 3 hours in a dark place. Add 1 teaspoon of dish washing liquid as a fixative just before use.
You can also steep your flowers in a jar filled with boiling water, and apply after it has cooled down.
However, the best way is to cover the flowers in a container with brandy, although kerosene and mineral oil will also work but not as well. Leave this mixture overnight keeping it away from any light. Strain the liquid and use 1 part liquid to 6 parts water.
To store your flowers place them in a freezer up to 6 months and use accordingly.

For those of you who live in Australia, and particularly Queensland, you are probably plagued with cane toads. Using them as golf balls in the dark is not very humane, although a common practice for the desperate! However, if you fill up a sprayer with pure Dettol and spray the cane toads directly, they will die almost immediately.
