As temperatures rise in our area, we have seen an increase in cockroaches. They become more active in warm weather and are often found in garages or inside homes, typically seeking water.
Our Wastewater Division is actively working to reduce cockroach infestations, as these pests are found in our sewer system. While often called "sewer roaches," this term is a misnomer. However, our sewer system's damp and dark conditions provide an ideal environment for cockroaches.
Contrary to reports from some pest control companies, we have not discontinued our protocols to manage cockroaches in our sewer system. We remain persistent in our treatment process to reduce cockroach populations, understanding that they are only a step away from your home.
Cockroaches are highly adaptable pests and can thrive in various settings, both indoors and outdoors. While they may temporarily shelter in our sewer pipes, they will unlikely enter homes from these pipes if customers' indoor plumbing is regularly used and properly maintained.
Upon receiving reports of cockroaches in the sewer system, we take the following steps:
- Dispatch our service workers to assess the situation
- Conduct thorough inspections of upstream and downstream manholes and customers' clean-out and lateral lines
- Perform pest control spraying on manholes and clean-outs using a product that is among the least toxic options available, following the product label instructions if cockroaches are found
We do not spray on the residents' side and encourage customers to contact a pest control company or use suitable products available at home improvement stores for their residences.
Cockroaches tend to be more active during hot weather. We suggest customers seal cracks and crevices in their homes and maintain a clean yard by trimming bushes and addressing potential hiding spots.
The Environmental Utilities Wastewater Division has implemented a proactive maintenance program to ensure the proper functioning of sewer pipes. If you have any problems, please call us at (916) 774-5750 anytime.
