Molasses Spray
Dissolve one tablespoon of molasses into a litre of warm water.
Add one teaspoon of dish washing liquid or other pure liquid soap

Spray regularly over the leaves of all plants attacked by caterpillars and other chewing pests. Caterpillars would rather starve than eat leaves sprayed with this mixture. It has also been used with success by some gardeners as a possum repellent and for the treatment of soil affected by root knot nematodes by doubling the concentration of molasses.
