Warning: my neighbor's "just spray vinegar" tip for roaches cost me $85 at a Decatur hardware store
My neighbor Dale swore up and down that a spray bottle of vinegar and dish soap would wipe out the roaches under my kitchen sink in Grant Park. I tried it for 2 weeks and the roaches just moved to the bathroom, so I caved and paid $85 for a pro visit last Friday. Dale says I got scammed and the pros are all a racket, but a guy at the counter said store-bought stuff barely touches a real German roach problem. So who's right here, are DIY fixes like Dale's actually worth trying or just a waste of time?
Dale's not totally wrong that some pros overcharge, but vinegar and soap is basically just wiping the counters down with a nice smell. German roaches live in the walls and cabinets, not on the surface, so spraying what you can see does almost nothing to the ones you can't. They came back because the nest was never touched, not because you did it wrong. Honestly $85 for a pro visit is on the cheap side, and the guy at the counter was right that store stuff barely dents a real infestation. Vinegar is fine for ants or wiping grease, but roaches need actual bait or gel, not a salad dressing trick.
