What Does a Cockroach Nest Look Like

Cockroaches are timid creatures and are rarely sighted during the day. However, they are most active at night and move around the place searching for food and water. A baby roach sheds its exoskeleton approximately eight times during the molting phase to transform into an adult roach.

The feces or droppings of cockroaches look like crushed black pepper or small pieces of burned coal or ground coffee spread over an area. A nest of cockroaches has a mildly intense musty, foul smell that is easily distinguishable from other foul odors. Want to hear what a colony sounds like?

Where do Cockroaches lay Eggs?

After the cockroach lays eggs, it takes approximately 45 to 50 days before the eggs hatch. The eggs emit a peculiar smell that can attract certain predators like lizards or house geicko. The eggs are also sensitive to drastic changes in environmental temperature.

Therefore cockroaches lay eggs in protected and hidden areas like closed cabinets, crevices and corners, under the old worn-out pieces of clothes, and unused shoe boxes. These areas are safe from environmental insults and can absorb the smell emitted by the eggs.
