Hartz Ultra Guard Plus Flea Collar for Dogs
White - For Necks up to 23"
SKU: 570745
Caution: Do not let children play with this collar.Directions for Use
It is a violation of federal law to use this product in a manner inconsistent with its labeling.
It is not advisable to use this or similar pesticides on puppies less than six weeks old.
Do not unroll collar until ready to use.
Place the Hartz Control Pet Care System Ultimate Flea Collar around the animal's neck, adjust to proper fit and buckle in place. The collar must be worn loosely to allow for growth of the animal and to permit the collar to move about the neck. A properly fitted collar is one that, when fastened, will snugly slide over the pet's head. Leave two to three inches on the collar for extra adjustment and cut off and dispose of the extra length.
Some animals may become irritated by any collar if it is applied too tightly. If this occurs, loosen the collar. If irritation continues, remove the collar from the animal.
This collar is intended for use only as an insecticide/IGR generator.
The collar will begin to kill fleas, ticks, flea eggs and larvae immediately. Its full protection against harder-to-kill ticks will be built up within a few days after being placed on the pet. For continuous flea and tick protection under normal conditions, replace the collar every seven months. Under conditions where pets are exposed to severe flea or tick infestations it may be necessary to replace the collar more frequently.
Wetting will not impair the collar's effectiveness or the pet's protection. If the pet goes swimming or is out in the rain it is not necessary to remove the collar. The Hartz Control Pet Care System Ultimate Flea Collar may be worn with a regular collar.
Storage
