Terrible. My landlord uses this company and we have gone through many full bedbug treatments since moving to the building. They must not do a thorough job and we always have to put down our own dust after spraying (even though they tell the landlord they have done this). We've just gone through yet another spray in our apartment and immediately are still experiencing bites every night. I even found a full grown adult bug the day alive the day after the treatment. I do not recommend this company.
