Supplied as a twin pack as two are often needed to treat a room. Foggers simply fill a room with an insecticidal smoke that fleas cannot avoid. There is no long lasting effect, but they are the perfect way to achieve an immediate control of fleas. The smoke is light and distributes evenly throughout a room far more effectively than aerosol foggers that project a heavy, water-based mist that falls quickly onto the floor. Contains permethrin 13.25% w/w.
