How is it that bed bug detecting dogs sniff for bed bugs?
Dogs have over 300,000 more scent glands than human and detect the presences of bed bugs without the use of sight. For centuries, dogs have been employed by the military and law enforcement to help with search and rescue. Since bed bugs can harbor inside furniture such mattresses and sofas making visual identification virtually impossible, bed bug detecting dogs can rely solely on the scent of the live bed bugs and viable eggs to detect them.
