Rats and Mice revisited
May 03, 2018 01:31AM
We seem to have an ongoing issue with rats and mice that gets worse (obviously) at this time of year.
Today I bought a plug in sonar repellant thing. Don't really know how to explain it except that you plug it in and it repels rodents over an area.
I am thinking I might need to buy a few but at around $100 each I do want to make sure that they work.
Has anyone else used these?

I will be interested to hear how the sonar repellant plug in works Helen - we too have current problems with mice getting inside. But, I have been a bit hesitant around the safety of these being plugged in continuously - so does anyone else use these & receommending them too? Thanks, am keen to hear more

We have had a couple of these devices for years (one at each end of the house) and I can report that they do work. They emit a high frequency sound (outside the range of human hearing), which rats and mice don't like. However don't expect immediate results - you need to have them on permanently so that said rodents get to know that your place is an uncomfortable place to be and they will gradually avoid it.

We live in the bush so you would expect to have a few problems, especially at this time of year as temperatures drop, but I can honestly say that the only evidence of rats or mice that I have seen for years are dead ones on the drive with a very smug looking cat hovering around!

We also have two in our home and no evidence. My electrician son also said that by plugging them in there is something transmitted via the wiring (he gave a more technical explanation which went over my head), and due to this, it also prevents vermin chewing on wiring in hidden parts of the home.
I have also seen these used in a factory office where they used to find mice droppings in cupboards, in the lunchroom and on the desk - absolutely not a single dropping in sight now for several years
Definitely worth the cost

We now have 3 plugged in at our place and yes as well as the high pitched sound (not even dog is bothered by it) they do send something along the electrical current that makes it uncomfortable for rodents (and cockroaches) to exist in the area covered.
Our house seems to have a plague of rodents so I am really hoping these work.

Cockroaches!! Don't get me started. I didn't know but they fly, and had one land on my neck. One huge black one scurry across my desk while I was working - they are all the horrible black ones, George even had one land on his face one night after we hopped in to bed - that sent me into violent hysterics.. I hate doing it but we have resorted to using cockroach bombs, but the frequency seems to be getting better. Initially it was every 3 months, and we have been able to extend that out to 4 or 5 months now. Have found the Mor***n 3 pack more effective with no messy residue as opposed to R**d, which also comes in a 3 pack

So after our experience with Cockroaches, followed by a bad bout of Pantry Moths, once I saw one mouse in the house - I insisted on two electronic zappers.

Great hints, thanks for these! Although my occasional rodent problem is due to cats bringing them in and then losing interest, so I don't think a zapper will be of much use for thatsmiling smiley. I wish there was a rodent detector on the cat door that would slam it shut when it could detect a cat carrying one approaching. And can I add to that a skink detector as well.

Oh Carolyn, I'm with you there on the rodent detecting cat door. The last week one of our three cats have brought in about 20 live mice. Usually we can catch and dispatch them, but I am very quickly tiring of having to chase mice around the living room at 3am. I'm not sure which is worse, live mice or the same cat's habit of regularly bringing in half a rabbit, always the rear half, and leaving it under my desk chair to snack on at a later time.

Argh, Jenna! Twenty in a week is hectic! The mice I don't mind so much, it's the rats. Getting rid of one of those required an all-nighter, so I sympathise with your 3 a.m. mouse huntssmiling smiley.

Irene, I've been scattering bay leaves around my pantry shelves for years now, and also putting one or two in every packet and jar of dried goods. Have never had pantry moths in any of the houses I've lived in! Wonderful deterrent and cheap, too.

Re the cats, rats and mice problem, I've had that for years, but now I keep my 'new' cat locked in from dusk to almost dawn and so far I haven't had a mouse or rat brought in. Can't say the same for the birds, though. And she always takes them under my bed to despatch them!

Lorna we already had the bay leaves scattered and it did not stop the pantry moths!

I tried festoons of bay leaves to deter pantry moths and it had no effect. The cardboard pantry moth traps you can buy at garden centres work quite well. The eggs arrive in all sorts of dried goods, particularly grains and flours but also spices.

We've been clear of them since I changed our eating habits to grain-free; I cleared out the pantry of all grains, flours and dried legumes, checked and discarded many infested spices (including chilli flakes) and set up pantry moth traps for a few months.

These days I keep white rice, rolled oats and lentils, all in lidded containers, and so far so good.

There's a great trap to dispatch multiple rodents called Goodnature [] It is for outdoors but if you're killing them outside your house, it means less inside it. And great for the environment as a whole - less rats eating birds' eggs, etc. Developed by New Zealanders for extermination of many of our pests in a much more efficient and labour-saving way.
Here's a video put out by Goodnature, showing how one urban NZ mother got rid of her severe rat problem within a month - []

Thanks for the reminder J1, I do think that having a Goodnature trap in the garden is sensible.
Our small street have been talking about collectively working to reduce rats in our neighbourhood so perhaps this is the way to go.
