Before we go too far on this poor horse, let's make it very clear: a
pesticide is any *substance* that is used to kill *pests*. This would
include sugar and detergent, as well as stuff like pyrethroids and
DDT. All pesticides are not created equal and not all are "bad". But
they should fit into an IPM plan.

An IPM system is designed around six basic components:

1.	Acceptable pest levels. We can't eliminate pests.
2.	Preventive cultural practice. This could include breeding for resistance.
3.	Monitoring. You don't need the pesticides, if you don't have the pests.
4.	Mechanical controls. Traps, barriers, etc.
5.	Biological controls. This would include pathogens that kill pests.
6.	Chemical control. As a last resort, you reach for chemicals.

There are three technical words used on pesticide labels that are
important to check.

1.      Caution: mildly toxic, more than an ounce would be a lethal
dose for a human (less for children).
2.      Warning: more toxic, a teaspoon to a tablespoon is a lethal
dose for an adult.
3.      Danger: (accompanied by the symbol of the skull and
crossbones), highly toxic - a minute amount can kill an adult.
