Ultrasonic Pest (in particular mouse) Repellers - do they work?

[RaisingMissDaisy]

Hi
I seem to have a little furry squatter. Sightings are very sporadic, but I'd rather get rid. I have ordered a couple of humane traps and after that I was thinking of getting some ultrasonic repellers. Does anyone have experience with these? Do they work, and if yes, can you recommend any?
Thank you!

@MrsAvocet 😫that is something that definitely puts me off using poison, but also the thought of the poor mouse suffering unnecessarily

Once the mice are established my experience was they didn't work.

If by humane traps you mean the ones that catch live mice so you can take them outside, they aren't humane either.

Mice need to be in a familiar place to survive. So either they walk back to your house or starve to death slowly.

Mice can climb walls (and iirc up the interiors of drain pipes) and get through a hole the size of a pencil tip. That's why you need a specialist to find the entry points.

Yes, this is the unexpected thing. The only 2 times I have been aware of rats, fortunately once being an outbuilding, they were most definitely in the roof and rafters and not lower down - thumping about pretty loudly and getting there by climbing a drainpipe and going along a gutter. My aunt had a mouse or 2 in higher floors of a block of flats, though allegedly none found lower down.

Sorry to say, but they scent-mark out their routes and hate (rats in particular) things that will interrupt or divert them in their set plan of their location. So, do that; if blocking holes, block up any drainpipe and climbing routes. Potentially try, sparingly and in strategic places, something that may be smelly as a repellent that also disrupts the 'route plan' alongside traps. There are things based on fox wee but I have never been quite desperate enough to try them as it may also be a step too far for inside, but I would try it in a roof.

They don't work. I have two which I've now switched off. I have 13 snap traps around, 3 humane traps and one of the electric zapper ones someone else has mentioned. We've put wire wool in lots of places but I still have a feckin mouse.

@AnnaMagnani 🙁seems like its either me or the mouse whatever I do

@Ormally i have seen sprays that contain menthol, castor oil, cinnamon..

anyway, I do now have someone coming round next week who can hopefully shed some light re: the best way forward

@Poggishairtufts you got yourself a supermouse!

Just be aware when you get an expert round they will identify the possible entry points & put poison down there. At least that’s what our expert did. It worked but I felt bad as had been trying to avoid poison.

I favour snap traps if infested, and electronic as deterrent - in that usually it trips with the first mouse in the building.

I like these methods because you simply dump the kill in an area where it can be scavenged, and that helps the population of the scavengers that would perhaps also feed on live mice.

@Twiglets1 and @Ariela thank you, more food for thought.

True, I suppose if the mouse dies in some hidden corner somewhere it does no good to anyone, as opposed to dumping the corpse somewhere outside after a hopefully quick death by electric shock or snap trap

If the mouse hunter wants to put down poison I may ask him not to 🤔

him or her! it may be a mouse huntress!
