The exclusive vapor action of NUVAN PROSTRIPS offers versatile bed bug control. Vapors from the strip move with air in a confined space to contact and kill bed bug eggs, nymphs and adults. Sensitive electronic equipment or other items can be placed in a plastic bag or container that is sealed to contain the vapors. Mattresses and box springs may be wrapped with poly sheeting. In many states, an entire room may be treated, providing the treatment is not disturbed by unauthorized persons.
