Here's the question that everything comes down to:
If you can't spray inside a wall void what can reach in there?
Sound can. Electromagnetic fields can.
PestLab uses two completely chemical-free mechanisms working simultaneously inside your space:
Mechanism 1 — Ultrasonic frequency disruption. Ultrasonic waves in the 20,000–65,000 Hz range completely silent to you, completely hostile to insects penetrate your walls, your furniture, your mattress seams, your baseboards.
They don't kill on contact. They don't need to.
They make your home feel neurologically unbearable to bed bugs. The frequencies interfere directly with their sensory systems the same systems they use to navigate, feed, communicate, and breed. Bugs traveling through building infrastructure that enter your unit encounter a zone of constant neurological disruption.
They move on.
And here's the critical detail: PestLab uses variable sweeping frequencies that shift continuously. Cheap ultrasonic devices use a fixed frequency that insects habituate to within days — it becomes background noise. PestLab's frequencies never allow adaptation. The hostility is constant and permanent.
Mechanism 2 — Electromagnetic pulse technology. Electromagnetic pulses travel through your walls, reaching structural voids and conduits that ultrasonic waves alone can't fully penetrate.
This addresses the exact pathways bugs use to travel between units in a building.
The shared walls. The electrical conduits. The plumbing runs.
Zero chemicals. Zero fumes. Nothing released into your air.
Completely safe around children, pets, and food. Just plug it in.
