NATURAL PYRETHRUM oil is extracted from the Pyrethrum daisy and been used as a natural insecticide since the early 1900’s. It has been proven to be one of the most environmental friendly low toxic insecticides as there is virtually no residue. Application at sunset is most effective as the product may break down in direct sunlight. Insects cannot build up immunity because of the complexity of its natural molecules. It is an effective contact insecticide with immediate knock down and controls a wide range of insect pests. It is very safe for humans on fruit and vegetables as it only has a one day withholding period.
