I had these guys start taking care of my pest prevention care last year. Since the beginning I started noticing more roaches outside than before ( whatever right? It's Vegas and roaches are a thing) but I draw the line when they come inside. I found one alive upstairs and a couple dead downstairs recently. My house isn't dirty and I've never had roaches inside before. Whatever they're doing isn't working. I might have to go back to the previous pest control company that actually sprays in the walls. I can't have roaches inside. I'll burn the house down.
