In 1990, the American Association of Poison Control reported that some 79,000 children were involved in common household pesticide poisonings or exposures.

Follow the directions carefully, and reread the directions on the label each time you use the pesticide. Use only the amount directed, at the time and under the conditions specified and for the purpose listed.
