It doesn’t end with the four fleas you’ve spotted in your dog’s coat. No, if they’re there you can be sure that there are at least a few more laying eggs in your dog’s bed, and all over the house in carpets, furniture and floor crevices. You treat your dog, but he gets re-infested again because the flea eggs in your household hatches at a later stage. Ultrum Duration Aerosol is the answer. You can use it on your carpets, in kennels, dog bedding and on furniture. It contains an insect growth regulator that instantly kills adult fleas on contact. Ultrum Duration Long-lasting Tick and Flea Spray ensures 2 months of active protection against biting fleas and over six months of protection against eggs and larvae.

One can of Ultrum Duration Spray covers 15 – 20 m².
