If Pesticide enters a waterway (stream or ocean) its effects can be quite devastating, years of over use of chemicals in Queensland Australia has lead to a slow decline in coral in the Great Barrier Reef.
Although the pesticides strength is obviously greatly diluted it is the cumulative effect that creates the long term harm to our environment. Fish living in the waterway will pick up the residue and this leads to a possible cross contamination of humans.
Use good Organic Gardening principles and you won't need to use pesticides, there are plenty of alternate organic pest control solutions available if you wish to give them a try.
