Asian Cockroaches in Northern Utah
In 1986, the Asian cockroach was identified as a newly introduced species to the United States when a professional pest control operator collected these insects in Texas. He referred to them as German cockroaches, but upon further investigation, the cockroaches were found to be Asian cockroaches. Although adult German and Asian cockroaches are similar in appearance, unlike German cockroaches, Asian cockroaches are strong fliers with sustained flights of at least 120 feet. The Asian cockroach is only a pest during periods of peak adult populations, in early spring and summer.
Asian Cockroach Habitat
Unlike German cockroaches, which prefer to live indoors and are a major household pest, Asian cockroaches prefer to live outside in mulched beds, compost piles, leaf litter, and lawns. When people first see Asian cockroaches they may think they are seeing little flying moths, or German cockroaches because the two species look similar. These roaches become active at sundown and are attracted to lights. They often fly inside structures through any opening such as lighted doorways or windows. Many people become upset when they see Asian roaches inside their homes, however, indoor infestations are rare occurrences.
Asian Cockroach Behaviors, Threats or Dangers
The behavior of Asian cockroaches is very different from the German cockroach. The Asian cockroach is an accomplished flier, prefers to live outdoors in shaded areas, mulch, grass, and compost piles, and rarely invades homes. At dusk, this species becomes active and adults are attracted to light reflected off light-colored walls, doorways, and windows. They may enter homes and rest on lighted surfaces, such as lampshades, TV screens, and walls. When lights are turned off, the cockroaches will follow to the next lighted room, making residents believe that these roaches are attacking them.
