The ultra sonic solution is a bit hit and miss
I don't intend to be always negative, but google says that is more than true.
"However, most scientific studies have found few or no signs that commercially available ultrasonic pest repellers actually work. Researchers at Kansas State University tested three devices in 2002 and found that none were able to repel ants in field or laboratory trials. Similarly, researchers observed no effect on bed bugs in a 2012 study that tested four devices or in a 2007 experiment involving German cockroaches and two types of mosquitoes.
Note that even the best ultrasonic pest repeller will not solve the underlying cause of pest problems. It will not eliminate the food sources that critters find appealing or the way they got into your home in the first place. As a result, you likely need to use other pest control methods simultaneously to address an existing infestation".
I'd be speaking to a local pest control guy - you can't be the first to be bothered. From experience - food and access are the keys. and traps or poison may be the answer. Subject of course to local regulations. Or Stanley's method.
PS Seems a similar idea works to deter teenagers. Quite how they describe it as ultra high frequency, and ultra sonic, when the frequency falls well in the range of a young human is beyond me.
The Mosquito The price of £500 plus VAT seems a bit steep though.
Morning
We have done everything that is advised. Pet controllers do not deal with this as the problem is too intermittent, and the price is horrendous, we have used them a couple of times to get rid of hornets nests. As for the ultrasonics, we do have some plug ins that have been very successful against mice and some battery operated ones that we keep at the door to stop cats entering. They too have worked, but we are aware they are not always successful. What we don’t want to do is poison them. If they die in the roof space we will have a dead rotting animal to deal with. As for food, they like fruit which is in abundance at the moment, and the access point we are convinced is straight up the wall which the can climb vertically and in under the open eaves. That can’t be blocked and even if it could we would need a roofer to do it….say no more. We have been waiting over two years for a roof repair
All the advice followed has come from official sources, and apparently the ones that really work are noise and naphthalene as they can’t abide the smell, but good old EU banned naphthalene in 2008. Camphor has been suggested as an alternative but we can’t find it in any shops. We can get it online from Amazon fr but postage and import duty amount to over £20, and would take three weeks, hence asking our friends to bring some from the UK. We use to bring it for our friends Audrey and Mike as a mouse deterrent .
Last night all was calm and the window cill is clean. We did a late clean up and disinfect of poo on the window cill near where we think they are getting in under the eaves. Bob then put down the cat and dog repellent powder, which smells atrocious to our human noses, but didn’t put them off in the roof the other night. Its not a remedy we can use when the room is used because of the smell. Every time we went in the room yesterday we banged on the roof with a window pole to disturb THEIR sleep, which we did do once. If we can just get them to dislike our roof space even temporarily we will feel happier when we have our friends staying. We await this mornings camera shots, which hopefully will show us an actual entry point. Meanwhile Bob is making an intermittent light that he will fir into the roof space, with electronic scarer as well.
Today Laetitia and family are coming for lunch, it will be an indoor sit down affair. Its been too wet to put up the outdoor gazebo. A bit of socialising will be nice. No rain forecast now for a week

. Have a good day all.
