Pesticide Environmental Stewardship Program (PESP)

Benefits and Risks Associated with Landscapes

To fully reap the benefits that lawns and landscapes can provide our urban and suburban communities, these green spaces must be well-maintained. Not only is pest management integral to this maintenance, but how pests are managed impacts the appearance, quality, and environmental conditions of a landscape. While pesticides can provide many benefits, they can also pose risks to human health and the environment.

Risks Associated with Landscaping

Risks associated with lawn care and landscaping include:

High Pesticide Concentrations in Urban Areas

The U.S. Geological Survey (USGS) water quality monitoring data indicate higher concentrations of pesticides in urban and suburban areas when compared to agricultural areas.

Pesticide Exposure Incidents

Improper pesticide use can result in unintentional, direct exposures to pesticides. According to EPA’s Pesticide Incidence Data Reporting System, more than 31,000 pesticide exposure incidents related to the use of pesticides on lawns were reported from 1995 to 2002. The major categories of the reported incidents were humans and non-target plants. These incidents are not confirmed or investigated.

Limited Consumer Knowledge

Inadequate consumer knowledge can result in poor lawn care practices – such as plant selection, irrigation, mowing, use (or lack of use) of fertilizer/soil amendments, aeration, and pest management – and improper pesticide use. Consumers often do not adhere to the instructions on pesticide labels or fail to read the labels altogether, which can lead to:

  • Applying more than the recommended application of a pesticide
  • Treating symptoms of pest problems without suitable information about the causes
  • Improper storage and disposal of pesticides

Public Health Pests

Landscapes can be habitats for public health pests such as ticks, mosquitoes, rats, and mice.

What Can YOU Do?

The Landscaping Initiative and its partners have produced guidance documents that help individuals apply responsible lawn care and landscaping practices, including:
