Optical Gel Dish Spacing for Other Bird Species

  • · Sparrows and swallows: 6 in.
  • · Starlings: 8 in.
  • · Corvids and cormorants: 10 in.
  • · Gulls: 12 in.

To avoid respiratory exposure, especially in confined areas, cleaners should wear a dust/mist filtering respirator meeting NIOSH standards of at least N-95, R-95, or P-95. Follow the manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions are available for washables, use detergent and hot water. Keep and wash PPE separately from other laundry.

Use a biocide or water mixed with detergent to wet surfaces where feces are present to limit generation of airborne dust and aerosol mists during cleaning. Allow cleaned surfaces to dry prior to treatment. When cleaning large amounts of bird debris, workers should be informed of the possible health risks involved. Persons with compromised immune systems should avoid the cleaning operation.

If pressure-washers are used to strip off dried feces, dust and aerosol control measures, such as containing the area with plastic sheeting, should be taken. Wetting down the work area will prevent inhalation, reduce the risk of disease from bird feces and debris, and will also help prevent the spread of dust & aerosols.

An alternative to use of a pressure washer is to soak the feces and debris with water and then use a shovel to remove them. The wet material should be collected in heavy-duty plastic trash bags or some other type of secure container and discarded with trash.
