While it's too early to tell how the treatment will work for our roach infestation, Akel was wonderful and answered all of my probing questions about roach nests and battling roaches in general. He didn't rush through things, took his time, and was really willing to speak to me about the process and this ongoing issue. Most of the time, exterminators dash in and out and are really dismissive of my questions but Akel was knowledgeable, patient and thorough. In terms of customer service, five stars. My hope is that this also translates into effective extermination of these little buggers! Fingers crossed!
