- Wood Cockroach -
What is the history of cockroaches?
Cockroaches are an extremely resilient insect. By examining fossils, it’s been determined that they have been around for over 300 million years. These days, there are more than 4,000 species crawling around. About 60 exist in the United States and around a dozen cause us to get out the insecticide.
What are some physical attributes of roaches?
The fact that cockroaches have been able to survive for as long as they have has made it extremely difficult in the past to control their population. Years and years of evolution have given them tough flat bodies and large legs for fast running and easy maneuvering. Other factors contributing to their enduring presence are the rapidity and frequency that they lay eggs and their possession of good climbing abilities.
What are Wood Roaches?
Wood cockroaches, also known as wood roaches, are common outdoor-dwelling insects native to North America and found throughout Iowa. Their normal habitat is moist woodland areas but they frequently become a household nuisance because they wander into or are carried into houses as “accidental invaders.”
What do the look like?
Wood roaches are very similar in appearance to the common household cockroach called the American roach; flat, oval body, long antennae, spiny legs, chestnut brown color. However, wood roaches are slightly smaller, about 3/4 to 1 1/4 inch long, and the adults, especially the males, appear tan because of the color of their wings. Adults and large nymphs of the wood roach can be recognized by a pale, creamy white or transparent stripe on the outer edge on the thorax. The pale edge extends onto the first 1/3 of the front wings of the adults. Positive identification of small nymphs is more difficult and usually requires microscopic examination.
What are they doing in my house
Wood roaches do not thrive and reproduce in homes because they require the consistently moist environment of their natural habitats such as under wood piles or loose bark and in decaying logs. Indoors, their presence is strictly a temporary annoyance. They do not harm the house structure, furnishings or occupants.
What damage can they do?
Wood roaches that have wandered into the house usually behave differently than the household roaches. Wood roaches are not secretive; they are active both during the day and at night and they are less likely to scamper out of sight when approached. Also, they will wander about the house without congregating in any particular location.
