Sewer Roaches

The City of Scottsdale maintains a very aggressive sewer roach control program that is designed to eliminate the sanitary sewer system as a breeding ground for sewer roaches.

Water and Wastewater Operations controls sewer roaches by spraying the walls of each City maintained sewer manhole with a chemical called Insecta.  The chemical is mixed with latex paint. When sewer roaches travel across the paint, they come in contact with the chemical.  Each treatment is effective for up to three years. However, to assure citizens that Scottsdale is committed to preventing sewer roaches, each manhole in the City is treated every other year.

Sewer Roach Treatment Schedule:

In the Spring of 2012 Water Operations will treat 5,540 sewer manholes between McKellips Road and Indian Bend Road and 8,094 manholes between Pinnacle Peak Road and the northern boundary of the city.

In the Spring of 2011 Water Operations treated 13,041 sewer manholes between Indian Bend Road and Pinnacle Peak Road.

In the Spring of 2010 Water Operations treated 5,540 sewer manholes between McKellips Road and Indian Bend Road. We also treated 8,094 manholes between Pinnacle Peak Road and the northern boundary of the city.

Facts

  • Roaches can enter your home in a number of ways – under doors, through air ducts, your sewer cleanout and any cracks or openings in the foundation
  • They prefer dark, moist places and can slip into the space as thin as a dime
  • Without a consistent food or water supply, they’ll quickly find another place to inhabit
  • Typically, they live in yards, plants and shrubs, under storage sheds, etc. - but once inside your home, your drains provide an ideal living environment for them

Tips for Controlling Roaches in your Home

  • Keep drains covered if not used for long periods of time
  • Attach properly fitted door sweeps
  • Store food in tightly sealed containers, including pet food
  • Pour ½ cup of bleach down the drain to keep it from drying out
  • Using a professional exterminating company to regularly treat your home both inside and out is encouraged (A one-time treatment usually only provides temporary reductions.)
  • Check boxes and cartons before bringing them in from storage – roaches don’t need a free ride into your home!
