Bedbugs are small, wingless insects found all over the world. They are nocturnal parasites, which means they rest during the day and are active at night. However, bed-bugs are opportunistic and will bite in the day, especially if starved for some time. They feed on the blood of humans and prefer to hide in bedding and on mattresses where they have ready access to a source of food. Although bedbugs can harbour diseases in their own bodies, transmission to humans is highly unlikely and there is no evidence for transmission of disease. They are not dangerous, unless a person is allergic to them. However, their presence can be distressing and their bites can be highly irritating! Please note their presence is not an indicator of poor hygiene!
