I found PestLab while searching specifically for something that could protect a new home from belongings arriving from an infested one.
I had tried ultrasonic devices before. They had done nothing.
But PestLab explained exactly why the old devices failed and why this was different.
Old ultrasonic devices used fixed low-power frequencies that didn't penetrate building materials. They made sound in the room. They didn't reach inside walls or appliances.
PestLab uses two systems working together.
Variable ultrasonic frequencies between 25 and 65 kilohertz validated to penetrate standard residential drywall and reach the enclosed structural voids where infestations actually live.
Plus electromagnetic pulses through wiring and building materials reaching the deepest hidden spaces that even ultrasonic waves can't fully penetrate.
Together, both systems reach inside walls, inside cabinet voids, inside the enclosed spaces around appliances.
Here's what finally made sense to me as someone who had opened a microwave and seen what was inside:
PestLab doesn't wait for a roach to come out into the open. It makes the structure itself inhospitable.
Even if something arrived inside my refrigerator motor.
Even if there were eggs inside a piece of furniture.
An environment saturated with PestLab's structural disruption means those things cannot establish, breed, or take hold.
My new apartment wouldn't just be clean.
It would be actively defended before the first box came through the door.
