Oriental cockroaches: common questions.
Are “water bugs” the same as cockroaches?
“Water bug” is a common name often used for oriental cockroaches because they are found in damp places. A photo helps confirm identification.
Why do I only see them in the basement?
Oriental cockroaches prefer cool, damp spaces and do not climb smooth surfaces well, so they tend to stay at lower levels.
Will fixing moisture help?
Moisture is a major factor for this species. Addressing leaks and damp areas is an important part of any plan.
