Field Cockroaches in Houston, TX
The field cockroach or vaga cockroach is a small cockroach and likely introduced from southwest Asia into the United States. This cockroach now inhabits a wide range from Texas to the West Coast and north through California. Field cockroaches are very similar in appearance to German cockroaches but can be distinguished by the blackish-brown area on the face from the mouthparts to between the eyes. Females may live for more than 200 days, producing between 200 to 300 offspring or 6 generations a year.
Field Cockroach Habitat
Field cockroaches feed largely on decomposing vegetation, including fruits, such as dates, and occur under stones, clumps of earth, and debris. Unlike German cockroaches, field cockroaches prefer to live outside in leaf litter and plant debris and rarely enter buildings. During drier parts of the year, field cockroaches may enter structures in search of moisture. Since field cockroaches so closely resemble German cockroaches, some homeowners will think they have German roaches invading their home, when they actually have field cockroaches.
Field Cockroach Behaviors, Threats, or Dangers
While they are not as widespread as other species, field cockroaches cause similar concerns. Field cockroaches are primarily outdoor cockroach species, and when found indoors, they may be treated as an occasional invader that will not take up residence indoors. Field roaches hide in cracks, crevices, and corners of homes. They can also spread bacteria if they gain access to kitchens and pantries. Populations of these fast-breeding cockroaches can increase rapidly if left unchecked. For that reason, always contact your local cockroach exterminators for help.
