**6. Health and environmental hazards of pest control**

Chemical insecticides are still considered as entomological weapons for the foreseeable future because of their wide host range, quick knockdown effects, easily availability to consumers. Their use in stored grain insect pests is still restricted as they pose threat to the health hazards and other environmental issues. Most of the chemical insecticides are carcinogenic and other health disorders [72]. The repeated application of insecticides leads to insecticide residues, secondary pest outbreaks. Recently the application of green synthesized nanoparticles is quite good and demonstrated satisfactory control against pulse beetle [73]. To overcome the issues of health and environmental hazards posed by chemical insecticides, workers are widely used other methods for their management. The satisfactory control has been observed when the product is not bulk and is being stored by physical and other methods which have been already discussed briefly in the chapter. Though, lot of botanicals have been applied to control a vast number of stored grain pests but satisfactory results are still wanted in large godowns especially in under-developed and developing countries. The villagers in these countries are still using the conventional methods and the damage levels are alarming and threatening. They even threaten the harvest which has been already harvested from different crops grown in the field and even protected conditions.
