Which method of fly control would be MOST harmful to other organisms in the environment? A Spraying broad-range insecticides B using fly traps C Planting carnivorous plants D Realeaing sterilized male flies

The right answer is A.

Insecticides are active substances or phytosanitary preparations with the property of killing insects, their larvae and / or their eggs. They are part of the family of pesticides, themselves included in the family of biocides, both of which are regulated in Europe by specific directives.

Some pestiids such as organoclorides are broad-spectrum, ie they act on several insects at the same time (whether they are good or bad).
