Why It Is Important For Pest Control Professionals To Control Cockroaches In Sewer Systems

Louisiana is home to numerous cockroach species, many of which are common household pests. In addition to being a commonly hated nuisance, cockroaches are also particularly filthy pests that are known for smearing numerous disease-causing microorganisms on human foods and indoor surfaces. This is not surprising considering that cockroach pests congregate on fecal matter and other forms of pathogen-rich organic materials. In fact, in the relatively warm southern states, cockroaches often become problematic pests within sewer systems where they become unbelievably numerous due to their ability to reproduce at a rapid pace. In big cities located in the south, like New Orleans and Baton Rouge, public health professionals are concerned about cockroaches invading homes after inhabiting sewer systems, which occurs frequently.

It is not uncommon for large sewer-dwelling cockroach populations to seek refuge within residential homes and buildings in response to rising sewage levels. Enormous herds of cockroaches have been found emerging from manholes and even indoor drains when heavy rainstorms and other factors drown out their sewer habitat. American cockroaches, and to a lesser extent, Oriental cockroaches, are the species most often found traversing into homes from sewer systems. In an effort to prevent this from happening, local governments have conducted area-wide cockroach control programs within sewer systems.

In order to exterminate sewer-dwelling cockroaches, many local governments have hired pest control professionals to pump insecticide formulations into manholes. In one case, pest control professionals used a gasoline powered centrifugal blower to pump insecticide dust into manholes, and another case saw officials use a portable crop duster for the same purpose. These insecticide dusts were specially formulated to exterminate American cockroaches, which have adapted a resistance to most insecticides. The American cockroach is the largest roach pest species in the US, as they often exceed 2 inches in length. The Oriental cockroach, another sewer-dweller, is around half an inch in length, and they are distinguished by their sluggish movements. Both the American and Oriental cockroach species can be found throughout the contiguous US.
