The Wastewater Collection section treats the public sewer manholes for cockroaches.  A latex-based insecticide paint is used to coat the inside of manhole walls. Once the insecticide paint is applied, it is effective at controlling cockroach re-infestation for at least two years.

The Roach Hotline (480-644-3550) is an easy way to report infestations or sightings of cockroaches suspected of originating from the City's sanitary sewer system. When a call is received Wastewater Collection Services will respond in one of two ways:Treating Manhole for Roaches

  1. Records will be reviewed and if the manhole has been treated within the last two years, the caller will be notified. No field check will be performed.

  2. If records indicate no insecticide has been applied to the manhole near the caller's address in the last two years, a field check will be performed. Nearby sanitary sewer manholes will be treated with insecticide and the caller will be informed whether roaches were observed or not.

Roach Control Tips

  • Keep drains covered if not in use for long periods of time.
  • Keep drains filled with water to keep P-traps from drying out.
  • Attach properly fitted door sweeps, caulk around windows and seal any cracks in a building's foundation.
  • Check for cracks or crevices in baseboards, water pipes, vents or windows that could be potential entryways.
  • Store food in tightly sealed containers, including pet food.
  • Use a professional exterminator to regularly treat your home or business inside and out.
