My two cats had unfortunately given me an apartment full of fleas, so had to be something that works well. Have the entire apartment now even completely sprayed from top to bottom and the next day no animals were visible. It is important for the product that you can, for example, not only the couch sprayed from a distance, but also in the cracks and if possible under the cushions! Of course, at the same time the cats have similar with flea bands be supplied, otherwise the whole thing makes no sense. Pay the entire procedure repeated in 3 weeks again ... Then we'll see !!!
