Recommendations given in previous editions of this book regarding use of
DDT and other “hard” pesticides are withdrawn in this 12th edition. We
advise, until questions about merits and dangers of these products are
resolved, that you contact a local agency before deciding what
pesticides, if any, to use.
We believe that every citizen should make a real effort to become
informed about pesticides and potential changes in them, for use or
non-use will likely have great impact on mankind’s future use of this
earth.
