Organic pesticides are safe for the environment.
These days the term "organic" has become synonymous with the word "safe." This is not true. Chemicals are chemicals and they all have an impact on the environment. The word organic means "of or relating to or derived from living organisms." Certain organic pesticides made from botanical extracts (e.g. pyrethrins) are highly toxic to aquatic life. Others can be harmful to human health (rotenone has been linked to Parkinson's disease). Even seemingly benign household products like salt, vinegar, dish soap or borax can harm microorganisms, alter soil pH and pollute groundwater systems. Although some organic pesticides are considered safer for the environment than certain synthetic pesticides, the best and least toxic gardening practices are those that use no chemicals at all.
