How and Why They are Inside

It is the sewer roaches' preferred habitat, where they can find wet and decaying materials in forests, alleyways, sewers, etc. Heavy rains or blocked sewer lines can lead to these insects climbing up drain pipes and sewer pipes.

Indoors, they look for damp, dark, moist areas kitchen cabinets, utility closets, basements, etc. The sewer is right next to your bathroom, which can lead homeowners to notice signs of cockroach and roach infestations.

Sewer Roaches

How do they get from the sewer to the building?

If they were to stay put, cockroaches would be no problem in the sewer. The problem is that they move around. American cockroaches can only produce one generation each year. Fall is when the full-grown Nymphs move, searching for winter food or places to stay warm. By squeezing through manhole covers, they can escape the sewers to reach nearby buildings. American cockroach infestations in commercial buildings is often traced back at the sewer system. Rainstorms and heavy rainfall can force cockroaches to flee combined sewers. A drain trap may dry out and the cockroaches will be able to walk through the pipes and through the trap, and then escape from the drain. It is not easy to solve the problem of cockroaches in sewer systems. The treatment of sewers with insecticides could become a regulatory and political issue. This would require coordination with the sewer authority, which might be the Public Works Department or Water and Sewer Department. It is more common for sewers to become infested by rats and cockroaches as they age. This makes it more challenging to resolve the issue.
