It’s a pity that I can’t open this link, I wanted to buy such a repellent.

Link no work.

The link is from over three years ago.

Items appear and disappear on Amazon all the time, so it doesn't surprise me in the least that the link doesn't work anymore.

Also, the OP hasn't signed in for over three years, so you can kiss this potential deal goodbye.

Hi, this post is from 2018, so it’s no surprise that the link is not valid. But if you go to Amazon, you can find a lot of good repellents there. I bought a bug repeller last year, and it protects us from mosquitoes and flying bugs. But we also had a problem with ants, and I didn’t find a way to get rid of them, so I had to hire specialists from a pest control company to solve this problem. By the way, I never thought that ants could be so annoying. The specialists did their work quickly and efficiently, and it didn’t cost me a fortune. So I am pleased with the quality and price of their services, and, if I have a problem with pests, I know where to call (0480 014 733).

Thanks.

On another note - is there any proof or reason to think these electronic pest repellants actually have any effect at all? Maybe they just annoy dogs.
I think they are probably a scam.

On a similar note; there’s an ‘old story’ that sprinkling Boric Acid on carpet kills fleas. I combed a couple fleas off our cat, then put them in a very tall glass flower vase with a floor of pure Boric Acid, and covered it. I could see them easily and watch what happened……which was……nothing after 3 days. I think if I had enough magnification they would have looked like beach goers basking in the sand, lacking only the beer. They could still jump quite well after all that time.

I have heard a similar “legend” that diatomaceous earth would kill, repel insects as well , but I haven’t gotten around to try it , myself. The stuff is supposed to be like shards of glass - microscopic shards of glass, so when a critter crawls across the stuff they are shredded.

I think that would work as well as a rabbit in a briar patch.
A flea is like a ‘tank’, a miniature crustacean.
