The Asian Cockroach
Asian cockroaches are considered a pest control problem, in many rural and suburban, single-family homes and yards; throughout the south-eastern United States. The Asian cockroach was first identified in the United States in 1986, when a heavy infestated area was discovered in Lakeland, Florida (Polk County). A second, more heavily infested region was identified in 1987, near Brandon and Tampa (Hillsborough County).
Today, the Asian cockroach is widely considered a significant pest control problem, in much of the south-eastern United States. The Asian cockroach predominately infests rural and suburban, single-family homes and yards. Outdoors, abundant populations of 30,000 to 250,000 cockroaches, per acre have been uncovered.
In some instances, the Asian cockroach could easily be confused with the German cockroach. In fact, entomologists believed the Asian cockroach is (possibly) an outdoor strain, of the German cockroach; which is thought to have originated in Asia. The wings of the Asian cockroach are usually longer and more narrow, than those of the German cockroach. Asian cockroaches are lighter in color than most German cockroaches. Similar to moths and leafhoppers, the adult Asian cockroach is a proficient flier.
The Asian cockroach is very susceptible to all pesticides. However, acceptable control of the Asian cockroach is difficult. Toxic baits applied to infested areas outdoors have provided the most reliable control. Cockroach baits have been registered for use outdoors. Because the Asian cockroach can fly 120 feet or more in a single flight, large areas around a home require treatment. Even so, cockroaches in surrounding untreated areas may result in reinfestation.
Residual sprays around the perimeter of structures are usually ineffective because there are numerous infested areas in lawns, mulch, and wooded areas. Adults enter homes through windows and doorways, and immediately fly to walls, avoiding baseboards and typical German cockroach harborages which are normally treated with pesticides.
