Does Riddex Plus Really Work? What We Found

The short answer

Does Riddex Plus really work? We can't confirm that it does. The seller provides no independent test, lab data, or third-party review showing the device drives away mice, rats, or roaches.

Here is what we can confirm from the offer page itself. Riddex Plus is a plug-in unit with a built-in nightlight. It sells for $34.99 for one unit (price checked 2026-11-07) and comes with a 30-day money-back guarantee. The maker rates one unit for homes up to 2,000 square feet.

We did not test this device ourselves. Everything below comes from reading the seller's own claims and what is publicly known about this category of product.

How Riddex is supposed to work

How does Riddex work? According to the maker, the device sends an electromagnetic pulse through your home's electrical wiring. The claim is that this pulse creates an environment pests find intolerable, so rodents and roaches leave the area or avoid it altogether.

That is the theory. The offer page calls the technology patented, but it gives no patent number, no test method, and no measured results of any kind.

It helps to separate two different things here:

• What the device is: a plug-in unit with a nightlight, rated by the maker for up to 2,000 square feet. These are specs we can verify from the page.
• What the device does: fewer pests in your home. This is the outcome, and the seller does not measure it anywhere.

The spec is real. The outcome is a claim. That distinction matters when you're deciding whether to spend your money.

What the seller offers as proof

Not much, unfortunately.

The offer page shows star ratings and two short buyer quotes. There is no study cited, no lab test, and no independent review of any kind.

The page also says most users report fewer pest sightings within 72 hours. We want to be clear: that is a seller statement, not a measured result. We have no way to check how that figure was produced, how many users were asked, or how their answers were collected.

More telling still, the advertorial's own disclaimer states that the results shown are illustrative and may not match what you experience. In plain terms, even the seller is telling you the results on the page aren't promises.

That's an honest disclaimer, and we respect it. But it also means the page's main selling point — quick results — is explicitly not guaranteed by anyone, including the maker.

What is known about plug-in pest repellers in general

Do Riddex pest repellers work as a category? The honest answer is that electronic plug-in repellers, both ultrasonic and electromagnetic types, have a mixed track record.

One public record is worth knowing. In 2003 the US Federal Trade Commission announced a proposed settlement with Global Instruments, which it said sold electromagnetic pest devices under the Riddex name on QVC. The order barred the company from claiming its devices repel or eliminate pests without competent and reliable scientific evidence. We do not know whether today's Riddex Plus seller is the same company.

That doesn't prove Riddex Plus doesn't work. It does mean you should treat this category with healthy skepticism, and you shouldn't expect the same kind of backing you'd get from a professionally applied treatment.

Does Riddex work on roaches, ants, spiders, or bed bugs?

Does Riddex work for roaches? Roaches and rodents are the two pests the offer page actually names. Those are the targets the seller claims.

The page does not mention ants, spiders, or bed bugs at all. We found no evidence in the seller's material that this device addresses any of those pests.

A special note on bed bugs, because this one matters: bed bugs generally require professional treatment. They hide in tight spaces near where you sleep, and plug-in devices don't reach them where they live. Do not rely on a plug-in repeller for a bed bug problem. Call a licensed professional.

If you try it, how to judge it fairly

Maybe you want to try it anyway. At $34.99 with a 30-day guarantee, it's not a huge gamble. That's fine — but judge it honestly. Here's how.

Before you plug it in, record what you see now. Count droppings, sightings, or trap catches per week. Write the number down. Without a baseline, you can't tell whether anything changed.

Give it two to three weeks. Don't judge after two days. Pests don't read schedules, and weather, season, and food availability all affect what you see. Compare your counts after a few weeks against your baseline.

Keep the basics going at the same time:

• Seal gaps and cracks where pests enter.
• Store food in sealed containers.
• Fix leaky pipes and taps.
• Take out trash regularly.

These steps help no matter what, and they're free.

Mark your return deadline on a calendar. The 30-day money-back guarantee starts when you order. Thirty days passes quickly, and if you see no change, that window is your refund. We don't know whether return shipping is covered or what condition the unit must be in — the offer page doesn't say. Check the terms before you buy so you're not surprised by return costs.

If the problem grows, call a licensed pest professional. An active infestation can get worse fast, especially with rodents, which reproduce quickly. A plug-in device is not a substitute for real treatment.

Bottom line

Riddex Plus is an easy, cheap thing to try. It plugs in, it has a nightlight, and it comes with a 30-day money-back guarantee. If you're curious, the guarantee softens the bet.

But its main claim — that electromagnetic pulses drive pests out of your home — is unproven. The seller offers ratings and quotes instead of tests, and its own disclaimer admits the results shown are illustrative.

Our honest advice: use it as an extra measure at most, alongside sealing entry points, storing food properly, and keeping things clean. Never use it as your only defense against an active infestation. If you have a real pest problem, a licensed professional is still the answer that comes with actual accountability.
