Cockroaches are insects that are often found in warm and humid areas. They usually live in places that provide easy access to food and water sources. Here are some places where cockroaches are often found:

In Storage: Cockroaches are often found in disorganized or dirty storage areas, such as drawers, sheds, or under stairs. They can hide among rarely used items or inside cardboard boxes and storage boxes.

In Trash Bins: Cockroaches can be found near trash cans or areas that are dirty and cluttered, they look for food sources such as food scraps and organic waste.

Near Pipes and Drains: Cockroaches can be found near pipes and drains, especially if there are leaks or high humidity. They are often looking for water sources.

In the Ground: Some species of cockroaches, such as the ground cockroach, live in the soil and look for food around them.

In Other Dark and Damp Places: Cockroaches can also be found in dark and damp places outside the home, such as in old boxes, under rotting wood, or behind bits of plants.

Cleanliness and Sanitation: An important first step is to maintain cleanliness and sanitation in the house. Clean up food debris, food crumbs, and food spills regularly. Make sure to clean the kitchen, bathroom, and food storage areas thoroughly.

Seal Gaps and Cracks: Cockroaches can enter the house through gaps and cracks in walls, floors, or doors. Make sure to seal or seal these gaps using sealants or other sealing materials.

Use of Traps : Cockroach traps can be used to catch cockroaches that are already in the house. These traps can be either adhesive traps or poisonous traps that attract cockroaches with a specific bait. 

Use of Insecticides: Insecticides are chemicals used to kill cockroaches. Insecticides can be applied in the form of sprays, powders, or toxic baits. Make sure to use safe and effective insecticides, and follow the instructions for use correctly.

Calling in the Professionals: If the cockroach infestation is too severe or difficult to control with the above methods, calling in pest control professionals may be necessary. These professionals have the knowledge and equipment necessary to effectively deal with cockroach infestations.

Use of Biological Control Methods: Some biological control methods such as using natural enemies of cockroaches or pest-controlling bacteria can also be used. However, these methods may require specialized knowledge and are not always available for use in all situations.
