Insecticides are either natural or chemically synthesized compounds which are used to control a variety of insect pests. Insecticides are a type of pesticide that is used to specifically target and kill insect pests. They are the chemicals used to control insects by killing them or preventing them from engaging in undesirable or destructive behaviours. The term insecticide is not as old as prior for killing the insects since very early times. As early as 200 BC a boiling mixture of bitumen and blowing the fumes through grape leaves was applied to keep the insect away. Sulphur and arsenic were known to be toxic for insects in 100 BC and about 40- 90 AD respectively. Pyrethrum is being used widely for insect control since even before 1800 in Persia. Neem leaves are being used as an insecticide since ancient times. The history of modern insecticide starts from 1867 with the use of Pares Green for reducing the population of Colorado beetle. After the discovery of insecticidal spectrum of DDT in 1939, insecticide property of BHC and potentialities of phosphorus chemicals in 1941-42, the real concept of insecticide and insect control revolutionized, as a result insecticide has become the boon of entomology. Insecticides show their toxicity into the living system. The World Health Organization classified them based on their detrimental effects, emphasizing the relevance of public health. The use of insecticides can be minimized to a least level, which is beneficial to both human health and the environment. Major literature focused on potential uses of insecticides, its classification and toxicity and their adverse effects on natural system, water, plants, human health etc. I have described here about the probable strategies by which we can minimize the most destruction effects of insecticides to save nature and its components.
