Bed Bug Terminator

OK, so I’m not even sure of the name of this place. Google says it’s Bed Bug Terminators, but the technician they sent out called it AA Pest Control, and when you call the number they just answer «service». So, it is sketchy to begin with. But a couple of months ago we found a single bed bug and FREAKED OUT. With our busy schedules we didn’t have time to shop around so I went with the exterminator listed nearest us.
Instead of a narrative, I’ll just provide a list of reasons you should NOT use this highly suspect business:
— not sure it is even a legit business (see name problem above)
— technician Dwayne was very nice and informative, even helped take our old mattress to the alley, but the price!
— $ 550 for one room. Dwayne told me what they use and it is just diatomaceous powder. I later discovered this is available at Home Depot for $ 10 in a big bag. He seemed to justify the price by the use of a plastic bottle that turned the powder into a mist and coated the room in the powder. I do like that they use all-​natural, non-​harmful materials — but $ 550???
— He did not give us a price before treating the room (granted, I should have asked) and the hand-​written receipt has no business information on it (again, see above).
— He told us that if we saw any signs of a bed bug return to call him «within 30 – 60 days». I said «Oh! There is a 60 day warranty» and he corrected me: «No. A 30 to 60 day warranty» — WTF does that mean? Again, I was too tired to ask.
— Just under 60 days later I found a couple of bites on my arm and again FREAKED OUT. I called «service» and they said that Dwayne would come out but he was not available until a week and a half later. I didn’t want to wait that long and asked if another technician could come out. «Service» said they would have to charge me another $ 45 inspection fee. After paying $ 550, I expected better customer service than this. Ridiculous!
Luckily, we have not found any evidence of re-​infestation, but after paying so much money, I expected a free re-​inspection.
In short, don’t waste your money on this «business». If you have a small infestation like we did, toss your old mattress and get some diatomaceous powder. Put it along the baseboards, etc and mist it in the effected room, lay down some sticky strips and let sit for a few days (make sure pets are away and you use a face mask — it’s safe as long as you don’t inhale it). If you don’t find evidence of bug carcasses, you’re fine. That’s all they did. Save $ 500 and use it towards protectors for your new mattress.
