SilentGuard™ Pro 2026 Upgraded | Electromagnetic Series | Plug in.

This is the right question to ask, and you're right to be skeptical.

The plug-ins you've tried almost certainly used ultrasonic-only technology. Here's the fundamental problem with that: ultrasonic sound waves are line-of-sight. The moment they hit a solid object — a wall, a cabinet, a piece of furniture — they stop. They can't penetrate. So you get a mild deterrent in whatever open space the device is pointed at, and nothing else.

SilentGuard™ Pro uses a dual-technology system. The ultrasonic component handles open areas. The electromagnetic component is what's actually different. It sends pulses through your home's existing electrical wiring — the copper that runs through every wall, floor, and ceiling already. That wiring becomes a distribution network. The electromagnetic field radiates from inside the walls outward, reaching the cavities where pests actually nest and breed.

That's not a marketing claim. That's physics. It's why cheap units don't work and why this does.

It works through walls — but understanding why matters, because most people assume it works the same way cheap ultrasonic devices claim to.

Ultrasonic sound cannot go through solid objects. Full stop. Any device claiming "wall penetration" through ultrasonic sound alone is either lying or confused.

SilentGuard™ Pro's wall penetration comes from the electromagnetic component. Electromagnetic pulses travel through conductive material — specifically, your home's copper wiring. Because that wiring runs throughout your entire house already, the pulses reach into the structural voids inside your walls, floors, and ceilings. That's where 90% of nesting happens. That's where the breeding population lives.

The ultrasonic frequencies handle open spaces. The electromagnetic component handles what's hidden. Together they cover the whole problem, not just the visible 10%.

Each SilentGuard™ Pro unit covers approximately 300 square feet. For most homes, the right approach is one unit per floor, placed in a central outlet where the electromagnetic pulses can distribute through the wiring on that level.

A common reason people try electronic repellers and get poor results is under-coverage. One unit in the kitchen does not protect a 2,000 square foot house. The pests simply retreat to a part of the home that isn't covered and continue breeding there.

For a standard 3-bedroom home on two floors: 2 units minimum, 3 for better overlap coverage. For larger homes or multi-level buildings: one unit per floor, positioned centrally.

This is why the 3-pack is the most popular option — it covers most homes completely, which is what produces the results people actually want.

Honestly: 14 to 21 days for most people. Some see a reduction in activity around day 10. Some take closer to 3 weeks. A small number don't see full results until week 4.

This is not an instant solution and we won't pretend it is. Pests don't experience one bad day and immediately leave. The electromagnetic field makes their nesting environment progressively more uncomfortable — their nervous systems are constantly disrupted, they can't communicate or feed normally, and eventually the space becomes uninhabitable. They relocate. That process takes time.

What the timeline looks like for most customers:

Weeks 1–2: Pests begin avoiding treated zones. You may still see activity, but it starts to decrease.

Weeks 3–4: Sightings drop significantly. Droppings stop. The scratching at night starts to go quiet.

Week 5 and beyond: Sustained protection as long as SilentGuard™ Pro remains plugged in. New pests won't enter because the environment is already hostile.

That's why we give you 90 days — not 30. Because 30 days isn't long enough to evaluate this properly.

No. Dogs and cats hear up to approximately 65 kHz. SilentGuard™ Pro operates between 25–65 kHz — at the upper range of that, which may cause very brief curiosity the first day in some animals, but nothing more. The vast majority of pet owners report zero reaction from their dogs or cats. They don't avoid the outlet, don't show distress, and after the first day typically ignore it completely.

The electromagnetic component is low-frequency and non-ionizing — similar in type to what your refrigerator, microwave, and phone charger already emit continuously. It doesn't affect mammals.

One important note: if you have pet rodents — hamsters, gerbils, guinea pigs, rabbits — do not use SilentGuard™ Pro. The ultrasonic frequencies that are harmless to cats and dogs will cause distress to rodents, including pet ones. Same goes for pet birds.

Then you pay nothing.

You have 90 full days to test SilentGuard™ Pro in your home. Use it every day. Watch whether the activity changes over 3, 4, 5 weeks. If by day 90 you're still hearing scratching, still seeing droppings, still dealing with the same problem — contact us and we'll refund every cent.

No hidden fees, no complicated process — just a straightforward guarantee designed to be fair and transparent.

We offer 90 days instead of the industry-standard 30 because we know this takes time to work, and because less than 2% of customers ever ask for a refund. Not because we make returns difficult. Because the dual-technology system works when single-mechanism devices don't.

If it doesn't work for you, you shouldn't pay for it. That's the deal.
