The two were determined to have brought the fleas and ticks also with the house. Our two pets have much outlet in forest and garden. And then we did it in spite of precautions can not prevent this came "vermin" with the house and spread.
After other attempts remained us only some chemicals. And that helped quickly and accurately in both rooms, one 20 and the other about 14 sqm: All textiles we have previously put into the washing machine, pressed tin on a chair, button, waited for an afternoon and then aired properly.
We have not found any more little creatures. Even now, nothing to see after more than a week. So were very satisfied, but continue to work, that the "Flohbus" gets no new passengers.
