It is not necessary to use Frontline Plus Spray with other Frontline products. However, to resolve both flea infestations and household contamination it is strongly recommended to use Frontline Plus Spray with Fronline Plus.
Hold applicator upright with foil side toward you and snap applicator tip. Part dog's hair between shoulder blades. Place applicator tip just above the skin and squeeze. Apply entire contents of applicator in a single spot directly onto dog's skin.
