How can the presence of rodents and insects be controlled in sewer systems?

The presence of rodents and insects in sewer systems can be effectively controlled by spraying manholes with approved pesticides. This method targets the specific pests that may inhabit the sewer environment, creating a barrier that discourages their presence. Pesticides are designed to eliminate pests quickly and efficiently, reducing their population and the potential for infestations.

In sewer systems, where food and nesting materials are readily available, relying solely on traps or natural repellents may not be sufficient, as these methods can often fail to address larger infestations. Regular cleaning of the area is important for general maintenance and may complement pest control strategies, but it does not directly eliminate pests. Therefore, the application of approved pesticides represents a more targeted and effective approach for managing rodent and insect populations in such environments.
