Contrary to popular belief, the name “wood roach” or “wood cockroach” doesn’t refer to a single cockroach species. It’s a loose term given to a lot of roaches in the world that have adapted to eat and even live in decaying wood. In North America alone, there are 12 species of these insects found in different states.
Wood roaches have the typical cockroach appearance of a flat oval body, legs with protruding spines and long antennae. However, they vary in color, depending on what species they belong to. In the US, a lot of wood roaches have a chestnut brown color. They also tend to only grow to about 1 inch long. Some of them also have cream colored lines at the edges of their wings.
Wood Roach Diet and Behavior
Even if they’re called wood roaches, these insects still eat other organic materials that can give them the nutrients to survive. They can eat human food, other insects and even animal droppings.
For their usual living areas, these roaches are largely outdoor creatures that thrive in moist places with dying trees, wood stumps and rotting logs. However, according the University of Nebraska–Lincoln’s Institute of Agriculture and Natural Resources, they oftentimes enter houses because male wood roaches are be attracted to the lights inside. They can slip through cracks and gaps in your doors, windows and walls. And they can also be accidentally carried in because of unchecked firewood brought from the outside.
Wood roaches are more or less better to deal with compared to their indoor counterparts. They’re not well-adapted to living inside houses, so they don’t scurry off when they spot you. And since they’re attracted to light, they don’t shy away when a room suddenly becomes bright. These traits make them far easier to kill even with just a flyswatter.
Another fortunate advantage for us humans when it comes to this cockroach is that these insects don’t breed indoors. That’s right. They can live under wood shingles, but they never mate inside houses. So they don’t infest, and their numbers typically don’t grow.
