Bell+Howell Ultrasonic Pest Repeller 6-Pack Complete Kit — 3 Sizes, Plug-In Silent Variable-Frequency Pest Control

The Bell+Howell Ultrasonic Pest Repeller Complete Kit is a six-piece set of plug-in devices that uses changing ultrasonic frequencies to encourage rodents and common household insects to leave your living spaces without chemicals or traps.

This compact kit from Bell+Howell contains two units in each of three sizes so you can cover countertops, hallways, and larger living areas. The devices operate silently, emit no odors, and rely on variable-frequency ultrasonic waves intended to make your home less hospitable to mice, rats, roaches, spiders, ants and mosquitoes. Because the units are plug-in, set-up is immediate and maintenance is minimal — no sprays, baits, or sticky traps required.

How does this kit protect different rooms of my home?

Each of the three sizes serves a specific placement and coverage need: compact units for small rooms or counters, medium units for corridors and basements, and larger units with an extra outlet for living rooms and bedrooms. Placing units strategically around entry points and activity zones increases the effective coverage.

• Micro unit: designed for tight spaces and near food prep or countertops.
• Classic unit: suited for hallways, basements and attics to intercept pests moving through the home.
• Macro unit: larger coverage and includes an extra outlet to preserve usability of that socket.

Will these devices bother my family or pets?

The repellers operate using ultrasonic waves that are intended to be inaudible to most humans and are advertised as safe for common household pets like dogs and cats. The kit contains no chemicals, emits no scent, and requires no traps or poisons, making it an option for households seeking non-chemical pest management.

• No pesticides, no aerosols, no bait—clean operation with no residue.
• Ultrasonic frequencies designed to be inaudible to adults and unobtrusive in daily use.
• Check veterinary guidance for exotic or small-pet species (e.g., rodents or reptiles).

How does the technology work and stay effective?

Bell+Howell’s units use variable-frequency ultrasonic emissions rather than a single tone, so the wavelength shifts over time to avoid habituation by pests. This pattern is intended to create a continuously irritating environment for insects and rodents, encouraging them to relocate.

• Variable frequency output reduces the chance pests adapt to a single sound.
• Continuous operation provides ongoing deterrence; plug in and leave running.
• Silent design means no audible disturbance while in use.

What practical maintenance or placement tips should I follow?

Placement and unobstructed line-of-sight are key: position devices away from furniture and behind counter clutter to maximize reach. Keep them plugged in continuously for ongoing coverage and rotate placement if you notice pest activity persisting in specific areas.

• Avoid blocking the front of the unit with curtains or large objects.
• Install near doors, baseboards and likely pest pathways for best results.
• Use multiple units in larger homes; two of each size are included in this kit.

Who is this for? This Bell+Howell six-pack is aimed at homeowners and renters who prefer a low-maintenance, chemical-free approach to reducing common household pests. It’s useful for families, shared living spaces, offices and garages where plug-in solutions are practical. While not a guaranteed extermination method for severe infestations, the kit is a cost-effective preventive tool or complement to other pest-control measures for those seeking silent, odorless deterrence from a trusted, long-established brand.
