About Repello

Written by the company

Om Repello

Repello utvecklar råttskrämmor och musskrämmor som bygger på vetenskaplig bioakustisk forskning. Tekniken är utvecklad av professor Örjan Johansson med koppling till Luleå tekniska universitet (LTU) och är vetenskapligt testad av Sveriges lantbruksuniversitet (SLU).

Det innebär något mycket konkret: Repello är världens enda råttskrämmare i sin kategori som har testats vetenskapligt av SLU. I en produktkategori där många konsumenter, myndigheter och experter öppet ifrågasätter effekten och där ord som bluff förekommer frekvent, har Repello tagits fram med en helt annan ambition.

Repello utvecklades just därför att marknaden för råttskrämmor och musskrämmor länge präglats av generiska ultraljudsprodukter, svepande påståenden och avsaknad av mätbar dokumentation. I stället för att fråga “vilket ljud skrämmer råttor?” ställde forskningen bakom Repello en annan fråga: hur varnar råttor varandra för fara – och hur reagerar de faktiskt?

Forskningen bakom Repello

Råttor och möss är sociala djur med avancerade kommunikationssystem. I forskningen bakom Repello har man analyserat hur råttor varnar varandra vid akut fara. Det sker genom artspecifika ljudsignaler, bland annat i ultraljudsområdet, och även genom ett särskilt tandgnissel som signalerar extrem stress och hot.

Forskargruppen lyckades spela in, analysera och återskapa dessa varningssignaler. När signalerna spelades upp i kontrollerade miljöer observerades att råttor omedelbart lämnade området och undvek att återvända. Det avgörande var inte ljudstyrka, utan att signalerna tolkades av djuren som ett direkt livshotande läge.

– Det handlar inte om att störa råttor med slumpmässigt ljud, utan om att tala deras språk. För råttorna låter signalerna som att något extremt farligt är nära, vilket triggar deras naturliga flykt- och undvikandebeteende.

Denna princip ligger till grund för Repellos råttskrämmare och musskrämmare. Tekniken är alltså inte “ultraljud” i generell mening, utan artspecifik bioakustik baserad på dokumenterat beteende.

Vetenskapligt testad av SLU

Repellos teknik har testats vetenskapligt av Sveriges lantbruksuniversitet (SLU). I testerna har gnagarnas beteende följts systematiskt före, under och efter exponering för de bioakustiska signalerna. Resultaten visade en kraftig minskning av råttaktivitet och ett tydligt undvikandebeteende.

Sveriges lantbruksuniversitet (SLU), Sveriges ledande statliga forskningsuniversitet inom djur, lantbruk och biologi

Detta gör Repello unikt. I dag finns det många produkter som marknadsförs som råttskrämmare eller musskrämmare, men Repello är världens enda som kan peka på vetenskaplig testning utförd av SLU. Det är också därför Repello ofta nämns som ett alternativ för konsumenter som är trötta på produkter som upplevs som bluff.

Inte gift, inte fällor – beteendepåverkan

Repello är utvecklat för dig som vill minska rått- och musproblem utan gift, fällor eller kemikalier. Tekniken dödar inte djuren. Den syftar till att göra miljön så obehaglig – ur djurens eget perspektiv – att de väljer att lämna området.

Repellos råttskrämmare och musskrämmare används i dag i villor, radhus, fritidshus, källare, vindar, garage, förråd och andra byggnader där man vill minska gnagaraktivitet på ett mer skonsamt sätt.

Det är viktigt att vara tydlig: resultat kan variera beroende på miljö, tillgång till föda, byggnadens utformning och placering av enheten. Därför lägger Repello stor vikt vid korrekt installation, tydliga instruktioner och support.

En reaktion på en ifrågasatt marknad

Marknaden för råttskrämmor och musskrämmor är en av de mest ifrågasatta konsumentkategorierna som finns. Många kunder har tidigare köpt produkter som inte fungerat alls, vilket har lett till frustration och till att ordet bluff ofta används i omdömen och diskussioner.

Repello togs fram just som en reaktion på detta. Vår ambition är inte att påstå att vi “garanterar resultat i alla situationer”, utan att vara öppna med vad tekniken bygger på, hur den testats och vilka förutsättningar som krävs.

Vi anser att det är den enda hållbara vägen i en produktkategori där förtroendet annars riskerar att urholkas.

Hopefully a great product.

Payment and delivery worked very well. I find that the light on the units is too bright. Furthermore, I hear the unit in the lounge making a high pitched chirping noise, which can be irritating. I have to add that I have excellent hearing. My husband can't hear it at all. I believe in the science of the product, but will not know if it works until the late spring when we return for the summer. I hope it does.

Do not believe the positive reviews

Do not believe the positive reviews. This company is fraudulent and their product does not work and is garbage. I tried to return with their “30 day money back guarantee”, however they gave me the runaround and played games and did not initiate any return. They should be ashamed of themselves for treating people like this. Stay away!

Not worth the hype

Bought 2 units on a ‘deal’ but still over £70 with postage. At first they seemed to do the trick - had them about 3 weeks. Just seen a mouse on the work surface in my kitchen right under the unit that is supposed to be repelling him safely!!!!! Not happy at all.

Hi Nicola,

Thank you for sharing your experience. We're sorry to hear that Repello hasn't lived up to your expectations, especially after initially showing promising results.

We completely understand your frustration at seeing a mouse so close to the device. Repello uses ultrasonic sound to deter rodents, but its effectiveness can be influenced by factors such as placement, obstacles and the layout of the room.

We'd really like to help you look into why you're not getting the results you expected and see what we can do to improve the situation.

Please don't hesitate to contact us at info@repello.com or +46 77 033 96 00, and our customer service team will be happy to assist you.

Kind regards,

Buyer Beware

Buyer Beware! I ordered a set of 5 plugins for insect repelling from Repellio @ 169.00 included tax & shipping and they charged me for more orders I didn't make 229.86 + 229.86 + 229.86 + 102.77. No help through PayPal; NO HELP THRU CUSTOMER SERVICE. Still don't have the product.

Hi Marilyn,

Thank you for sharing your experience. We're very sorry to hear about the issues you've experienced with your order and the lack of support you've received.

We would like to clarify something, as we suspect there may have been a mix-up between two different companies.

Did you happen to place your order through repello.de? This is a separate company operating in Germany and is not affiliated with us at Repello.

We also noticed that you mentioned insect repellent plug-ins, which are not part of our product range.

We would really appreciate it if you could confirm which website you ordered from, so we can help clarify the situation.

Kind regards,
Team Repello

Essentially it does what it says on the tin.
Past two years we have had rats in the eaves, started using the sonic deterrent and not a rat to be heard and we're are in the middle of a cold snap.
As far as I an concerned great product.

Great product / poor shipping experience

Updating the original review, which is below for reference.
3 Repellos finally arrived 3 months ago and installed them at my attic (60cm of loose-fill insulation above the first floor of the house - cold, open and not in use). Area of ca 160 sqm. Within 2 winters mice had constructed a metropolis of highways and hubs into the 100 cubic meters of soft warm insulation and poisoning only resulted in 1 month of silence at a time. And also rotting corpses inside the walls eminating through the wall sockets.
When installing the 3 repellos I also used poison to get rid of the current knowledgable residents. Took 2 weeks and silence has followed. Not a single sound from the ceiling so far and it's been 2 months of -15...-20 celsius now, what should accelerate the mice migrating inside.
Great!
Will post the final verdict in spring when it's clear if it works 100% or not. My conditions seem like the most difficult to get rid of the mice so should be a good reference.

The initial review:
--- Nothing has happened after 3 weeks from ordering and no-one is answering any mails. Will have to seek help from local consumer protection agency to try to get money back. ---
