I needed something that could reach inside walls.
Something with no airborne residue. No chemicals. Nothing that settled on surfaces or drifted through air vents.
Something that worked where the actual infestation was hiding without adding a single particle to the air Sofia breathed.
That's when I found PestLab.
I almost scrolled past it.
I had tried a cheap ultrasonic gadget years before that did absolutely nothing.
But PestLab explained something that made me stop.
Earlier ultrasonic devices failed because they used the wrong frequencies and didn't penetrate structural materials.
PestLab emits specific frequencies that travel through walls, through drywall, through the voids behind appliances directly into the spaces where hidden colonies live.
Inside those hidden spaces, the frequency creates continuous disruption.
Roaches cannot function normally. Cannot breed comfortably. Cannot stay.
No chemicals. No spray. No airborne residue of any kind.
Just sound waves that travel exactly where the infestation actually is.
For a child whose lungs react to airborne particles, this wasn't a convenient feature.
It was the only option that made any sense at all.
