Behavior, Diet & Habits
Cockroach is quite an adaptable insect in their environment but mostly prefer to live in warm conditions. Mostly active during the night foraging for food and water, they can be found in bathrooms, kitchen sinks if there is left over food left unkept, kitchen cupboards and in some areas around the home where there is access to food and water. Because of their flattened shaped bodies, they are able to easily transfer from one unit to another through the shared plumbing pipes. Cockroach communicates with other cockroach by leaving chemical trails in their feces. In a home when a large number of cockroaches are present it can be noticed through the mild musky odor in the area and cockroach dropping is also found in areas like the drawers and countertops, sometimes inside cupboards. Cockroach fecal staining is also commonly found. They feed on almost any food they find but is not limited to bookbinding and soap.
A female cockroach carries her eggs in her abdomen. The thin and long egg case carries about 30 to 40 eggs. It takes the cockroach 5 hours to lay the egg capsules.
