Oriental Cockroaches in El Paso TX and Anthony NM

Unlike the American and German roach varieties, the Oriental cockroach is large with a glossy black body. They also move much slower than other roach varieties. They aren’t bothered as much by the cooler climate and are more likely to be found outside in bushes, under mulch and leaf ground cover, and around other damp areas. These roaches in particular are extremely elusive and can hide in plain sight even after casual inspections. People often call these roaches “water bugs” or “black beetles”. They are known to climb water pipes and garbage chutes to access the upper floors as well.

Oriental Cockroach Environment or Habitat

German cockroaches are seasonal and adults generally appear from May through July in the El Paso area.  Oriental cockroaches are common outdoors and live in warm, damp shady areas near the ground. Outside the house, these cockroaches will gather near or under trash cans. When temperatures drop, they may seek shelter indoors but can tolerate cooler weather. Oriental cockroaches may enter homes in food packages from grocery stores or gain access under exterior doors, garage doors, through air ducts and ventilators. Inside, they tend to remain on lower floors and move more slowly than other species. The most common areas to find oriental cockroaches in homes are toilets, bathtubs, sinks, radiators, and pipes. 

Oriental Cockroach Behaviors and Threats

Oriental cockroaches rarely bite and do not damage homes. The main concern is the fact that they can spread bacteria and germs. Cockroaches are known for spreading disease and have been discovered to carry 33 different kinds of bacteria, including E. Coli and Salmonella. Cockroaches contaminate food items and the surfaces in our homes with harmful bacteria as they forage for food. They also pose a major threat to people with allergies or asthma as their shed skins and feces can cause serious reactions in these individuals. For this reason, always contact your local cockroach exterminator for help with oriental cockroach infestations.
