All pest species – including roaches – have their own unique ecology. To help avoid or resolve infestations, understanding their biology is crucial.

German Roaches

German roaches are the most likely species to cause issues at your facility, as their rapid reproduction rate allows populations to grow exponentially.

  • Ideal habitat: German roaches prefer moist, dark cracks and crevices close to food sources.
  • Where to look: Look in hollow doors, insulation seams of steam pipes, cracks behind wall panels or shields, hollow equipment legs and other empty spaces in equipment and structures.
  • How to resolve: Seal cracks to help prevent or block access to harborages. Also, use small baits spaced a couple of feet apart. Bait is often taken back to the harborages by the adults through toxic feces, secretions and dead bodies that kill the young that have yet to emerge.

American Roaches

American roaches are an indoor and outdoor species depending on the time of the year.

  • Ideal habitat: American roaches prefer warm environments.
  • Where to look: They can be found in utility steam tunnels, boiler rooms and some drains and sewers.
  • How to resolve: Because of their large appetites, adequate amounts of bait need to be placed around the area. Other techniques to help with prevention and correction include frequent drain cleaning, applying residual applications outdoors or in tunnels and using approved dust applications in manholes.

Oriental Roaches

Oriental roaches are also an indoor and outdoor species.

  • Ideal habitat: Oriental roaches prefer dark, cool environments.
  • Where to look: Check out crawl spaces, drains and cooler cellars.
  • How to resolve: Use the same tactics utilized for American roaches.

Other roaches to be aware of include wood roaches and brown banded roaches. Wood roaches can fly and prefer to live in places where damp and rotting wood are present – like poorly designed walls and roofs. Brown banded roaches can be found in offices eating glue on envelopes and book bindings.
