Cockroaches or roaches are primitive insects. They date back to the era, “Carboniferous,” millions of years ago. Roaches are omnivorous, eating anything available including glue and soap just to survive. Species of cockroaches that require water, food, and indoor harborage that’s provided by humans are lesser in number compared to the peridomestic ones, those that occur outdoors and don’t require human habitat.

The Telltale Signs of a Roach infestation

Roaches, as nocturnal creatures, hide during the day. At night, they can be seen on top of kitchen countertops, dining tables, and basins. Their egg cases and cast skins can be seen strewn on objects that haven’t been touched or used for quite some time.

Floor-wall junctions and horizontal spaces are the common places where you can find droppings of roaches. They are dark brown or black in color, and irregular or cylindrical in shape.

Cockroach infestations are easy to identify because of their musty, unpleasant smell. The smell is noticeable close to their harborage points
