Behavior, Diet, & Habits

Where Do They Live?
Surinam cockroaches are destructive pests that prefer dark and moist areas. These insects may be found in places such as:

  • Beneath objects
  • Corners
  • Gardens
  • Greenhouses
  • Tropical plant soil

Geographical Range
These garden pests are most commonly found in humid, tropic areas such as the southeastern United States.

Reproduction

Surinam cockroaches reproduce through parthenogenesis, allowing females to produce offspring without fertilization from males. Thus, all Surinam cockroaches in North America are females. Since these insects can reproduce at will, infestations quickly get out of control.

Their eggs are hidden within the female’s abdomen and hatch internally. They may have an average of 3 egg cases which contain an average of 24 eggs.
