Riddex Sonic Plus Ultrasonic Pest Repeller 3-Pack - Odorless Indoor

In this review the Riddex Sonic Plus Ultrasonic Pest Repeller 3-pack is evaluated for homeowners who want a simple, chemical-free way to deter rodents and common household insects. The single biggest reason to consider it is its plug-in, odorless ultrasonic approach that claims to cover up to 1000 sq ft per unit, making it an attractive option for those who need continuous, low-effort protection without traps or sprays. It is especially appealing to families with pets or children who prefer a non-toxic solution.

Key Features

• Odorless ultrasonic: Emits ultrasonic waves that are designed to agitate pests without producing any smell, so it does not leave residues or fumes in living spaces.
• Wide coverage: Each unit is specified to cover up to 1000 sq ft, allowing a 3-pack to provide layered protection across multiple rooms or a larger area.
• Side outlet included: The built-in side outlet is UL approved, so you can keep another device plugged in and avoid losing a usable wall socket.
• Safe for family and pets: The electronic, chemical-free operation is presented as safe to use around kids, cats, and dogs compared with sprays and baits.
• Plug-and-play installation: The compact, low-profile design requires only plugging in to start continuous operation, with no setup or maintenance like refills or traps.
• Multi-pest claims: Marketed to deter mice, rats, cockroaches, spiders and other common household insects using electromagnetic and ultrasonic deterrents.

Who It's For

This product suits renters and homeowners who want a low-maintenance, non-chemical pest deterrent for indoor spaces and who prioritize safety around children and pets. It is useful for people looking to supplement other pest-control measures or to cover entryways, kitchens, basements and garages where occasional pest visits occur.

Those who need guaranteed immediate elimination of an active infestation, require outdoor treatment, or who are highly sensitive to any emitted frequencies should consider traditional traps or professional pest control instead. Also, users wanting a silent device should note some customers report audible noise in certain environments.

Pros & Cons

Pros

• Easy plug-in operation provides continuous, hands-off protection without chemicals.
• Side outlet preserves wall socket usability, making it practical for everyday use.

• Low-profile design is unobtrusive and family-friendly for homes with pets and children.

Cons

• Effectiveness varies by home layout and pest type; some customers report mixed results.
• A minority of users note an audible noise, so it may not be completely silent in every room.
