Short answer: PestGuard is a plug-in that emits ultrasonic sound intended as continuous chemical-free SUPPORT in an open room zone. It is not a spray, not a poison, not an EPA-registered pesticide, and not a kill or eradicate promise. Mechanism honesty matters more than marketing buzzwords.
What the device is doing (plain language)
- Continuous plug-in: Once powered, it runs as ongoing room SUPPORT—not a timed “blast” like a spray can.
- Ultrasonic output: High-frequency sound aimed at room coverage in open air. Walls, closed doors, and thick clutter shrink the useful zone.
- Chemical-free framing: No spray residue cycle. That also means it cannot do what labeled contact treatments are designed to do on seams and crevices.

What “work” does and does not mean
| Claim people hear | Honest frame |
|---|---|
| “It works on bed bugs / pests” | Optional SUPPORT in one open zone while you keep inspection and a real treatment plan. Not a clearance proof. |
| “It kills / eradicates” | No. PestGuard does not make kill or eradicate claims and is not an EPA pesticide substitute. |
| “One plug covers the whole house” | No. Plan per open zone. See how many pest repellers per home. |
| “It replaces Raid / Hot Shot / a pro” | No. Sprays and pros are a different category. Comparison: Hot Shot vs Raid. |
Limits you should expect
- Closed doors and furniture clutter reduce coverage — placement near furniture & clutter.
- Shared walls / apartments need realistic expectations — ultrasonic for apartments.
- Continuous runtime is the SUPPORT pattern, not on/off cycling — how long to leave it on.
- Pets: read pet-safe framing before you plug in.
When SUPPORT is not enough (escalate)
- Live bugs, eggs, or spreading activity across rooms / units
- Bite-related medical questions (clinician—not a plug-in page)
- Activity continues after honest inspection + barrier / labeled or pro plan

FAQ
How does PestGuard work compared to sprays?
Sprays are contact / residual products used as labeled on specific surfaces. PestGuard is continuous ultrasonic SUPPORT in open air—different job, different limits.
Will I hear it working?
Ultrasonic output is generally outside typical adult hearing. “Quiet” does not prove coverage or clearance—inspect seams and follow a real plan.
Is mechanism the same as “it will clear my home”?
No. Mechanism explains what the plug-in is for (SUPPORT). Clearance still depends on inspection and the right barrier / treatment path.
