Surinam cockroaches are mostly found along the coast, where they can become very numerous in lawns. Sometimes they are transported in plantings used in shopping malls. Wood cockroaches are a group of minor cockroach pests. They are native to North America. Males are usually plain brown and 1 inch or less in length.
Females are shorter and broader than males.
Generally, females range in color from light to dark brown, with wings only half the length of the body or shorter. Males are good fliers and are often found around lights at night. Sometimes males fly into buildings. Outdoors, wood cockroaches are found in areas such as wood piles, mulch and leaf litter. Indoors, wood cockroaches cannot survive very well and are seldom a problem.
