We often see them in bathrooms. Because they are close to sewers and drains, the incidence of activity is high. Being warm and humid allows them to nest in these areas. If the drains are not kept clean and closed, a suitable environment for cockroaches is prepared.
Not all ant species can be seen in bathrooms. Pharaoh and carpenter ants are often found in bathrooms. They prefer bathrooms because they like warm and humid areas.
Other types of insects such as spiders, centipedes, silverfish can also be found in bathrooms. Regular cleaning and sealing openings will prevent insect activity.
