My husband and I recently moved into an apartment only to find that it is infested with fleas. We contacted management and they had a pest company spray our apartment. We waited a few days but there didn't seem to be any reduction in the amount of fleas. So (and, in retrospect, we should not have done this, but we were desperate) we fogged the apartment ourselves. For a few days after, it seemed we had gotten rid of them, but they are back with a vengeance. We confessed to the management that we fogged and they said that fogging will reduce the effectiveness of whatever the pest company sprayed. We were just wondering if anyone has heard of this or know it to be true, or if it just sounds like they are feeding us a load of bull?
