Lawn Pesticide Fact Sheet

  • Of 30 commonly used lawn pesticides, 19 have studies linking them with cancer, 13 are linked with birth defects, 21 with reproductive effects, 15 with neurotoxicity or abnormal brain development.1
  • Children are particularly susceptible because of their rapid growth and decreased ability to detoxify toxins.2, 3.  This is particularly true for the developing child in utero.
  • Studies link some lawn pesticides to hyperactivity, developmental delays, behavioral disorder, and motor dysfunction.,4, 5, 6
  • A Study in the Journal of the National Cancer Institute found that home and garden use of pesticides can increase the risk of childhood leukemia by almost seven times.7
  • The lag time between environmental exposure and the development of lymphoma can be as long as 20 years.8
  • Lawn pesticides can be tracked inside of schools where they can persist for long periods of time contaminating air, dust, surfaces, and carpets and exposing children to these toxic chemicals even if they are not in contact with the grass.9
  • There is provision for pesticide use if there is a condition that threatens the health and safety of the children.  For example, an underground wasp nest or an infestation of ticks.
  • There are significant gaps in the safety testing of toxic lawn pesticides.10
      • Lawn pesticides are not tested for long term toxicity unless they are also used on food crops.
      • Lawn pesticides are not tested in the combinations and formulations in which they are actually used.  Yet, these combinations and formulations can be more toxic than the pure active ingredient.
      • It is the chemical companies themselves that supply the safety testing data to the Environmental Protection Agency.
  • Lawn pesticides can contaminate well water.  11% of residential wells tested in a Connecticut town showed the presence of one or more lawn pesticides.11
  • There are safe, effective, affordable alternatives to using toxic lawn pesticides.  A number of towns in Connecticut have successfully switched to pesticide-free organic lawn care.12, 13
  • With so many unknowns and with plausible evidence of harm to children, it makes no sense for our children to be involuntarily exposed to the unnecessary use of these toxic chemicals especially when there are safe, effective, affordable alternatives.
