Habits
The smoky brown cockroach is a nocturnal insect that typically lives outdoors; hiding under vegetation and yard debris, heavy mulch layers and thick leaf litter. These cockroaches are extremely common in Texas and Louisiana where they have also become an indoor problem.

Diet
These cockroaches prefer to eat plants and are therefore often a pest in greenhouses, nurseries and gardens.
