I can only recommend. 100% success. We had our dogs with massive flea infestation. After we treated our dogs with Frontline and our apartment have everything cleaned and washed, curtains, blankets Sleeping dogs, etc., we have set up the traps at night and thus captured the last living fleas. One should the case a few days up in succession, because fleas lay their eggs and hatch after a few days new fleas also can go for a lure into the trap and thus clean the apartment. I have our apartment additionally sprayed with Chrysamed, on carpets furniture, etc., since I could not set up a trap in every room and just to be absolutely sure that in the smallest nooks and crannies all be killed.
