Will Flea Spray Kill Lice?
Yes, some flea sprays, like Nyguard Plus, are labeled to kill lice as well. Spray only surfaces that cannot be laundered or dry-cleaned including mattresses and upholstered furniture. Apply on mattresses as a spot treatment to mattress seams, edges, buttons, and tufts of bed only. Do not use directly on pillows, bed linens, or cloths. Do not saturate the mattress and do not treat entire surface area of mattress. Allow mattress to dry thoroughly before replacing pillows and/or bed linens.
