One concern: what does DDT do to pollinating insects such as bees? Is there such a thing as too much of it?
Not good for them, which is why proper pest management know-how is vital to farmers. Indiscriminate spraying of DDT or any other pesticide can do more harm than good on a farm, which is why most farmers spray at specific times of the year and use products that break down quickly. The problem with DDT in agriculture is that it lingers, the same characteristic that makes it ideal for use in homes to eradicate disease-carrying insects.
