Where’s the Best Place to Use Ultrasonic Pest Repellers?
Expert Tips to Maximise Their Effectiveness in Every Room
Ultrasonic pest repellers are one of the most convenient, humane, and non-toxic ways to get rid of rodents — but their effectiveness depends on where and how you use them.
Positioning without planning like - behind furniture can limit its effectiveness. At PESTFREEHOME, we want to help you get the best results from your ultrasonic devices — while combining them with smart, non-poisonous solutions for long-term rodent prevention.
Let’s break down the best locations, common mistakes, and product pairings that work like a charm.
Living Room / Lounge
Rodents often pass through living spaces at night when the home is quiet.
Best Placement:
Plug directly into an open wall socket ( not behind sofas, curtains or other obstacles )
Aim across the longest open wall for maximum coverage.
Do not block them in - use Repellent as a way to direct.

Kitchen
A common hotspot — crumbs, pet food, bins, and warmth make kitchens rodent heaven.
Best Placement:
Place it as close to the entry point as possible on ground level.
Keep it clear of water or heat sources like kettles and sinks.
Don’t plug into extension leads or multi-sockets.
Avoid Plugging behind any obstacles that could interrupt the wave.

Bedroom
While we do not recommend to place it in bedrooms at all, especially children bedrooms as rarely rats will enter such rooms anyways. If you do - we recommend to use it while you're not in the room - like overnight. Use it on the low setting or slightly less powerful device.
Best Placement:
Plug in the socket that is facing across the room.
Avoid placing close to bed and behind any furniture ( curtains etc )

Garage / Loft / Utility Room
These areas are rarely visited by people — perfect nesting areas for pests.
Best Placement:
Use two repellers if space is large or has multiple entry points.
Place in open view, high up or facing suspected access holes.
If no power socket, use ultrasonic models with extension-safe plugs.

Inside the Car ( Yes, Really! )
Rodents often chew through wiring, nest in engine bays, and cause serious damage.
Best Practices:
Place device in the car ( preferably closer to dashboard ) as it's near engine compartment or back if you're lucky enough to have a super car. Leave it on working overnight or when vehicle is not in use. No, it won't affect your neighbours.

Common Mistakes to Avoid
Plugging behind furniture or curtains ( blocks sound waves )
Using extension cords or multi-plugs ( reduces performance and safety )
Expecting instant results ( give it at least 7–10 days )
Blocking rodents in, so they can't escape.
