Ultrasonic Pest Control Set of 6-Packs Electronic Plug in Repellent Indoor for Pest Control

2 months and no results. I think electromagnetic products work, but not ultrasonic.**UPDATE** seller has been begging me to remove my review...But, they did not work for me.

What a little handy and aesthetic device, serving as an unobtrusive nightlight as well. Having 2 cats and a dog I don’t use any chemicals in the house, which invited different spiders to come in and occupy corners in the floor area, to the great dismay of my female cohabitants. I sucked up the uninvited tenants with the vacuum, put the devices out and have not seen another spider. I watched my cats and dog, if they would react, by plugging the device in and out. There was no reaction at all.

4 of them worked very well. One was coming apart and one quit working immediately.

Got this for my basement which has a lot of cricket spiders. I used 2 units for the entire basement. Got rid of those creepy spiders within a week. I saw a small spider once but those big ones are gone. Very happy with this purchase.

I was in a hurry to find a product to rid my home of pests that found their way under the foundation and into some of my walls and attic. The scratching, digging and walking around really disturbed my life. This arrived in 2 days. The FIRST day I plugged them in I heard scratching in one wall for about an hour, then NOTHING.I turned off everything to listen and make sure.The unwanted visitors are gone!What a relief! Buy it!You will see results faster than they advertised!!!

The decision to buy its was made due to the fact that with the warming a huge number of ants appeared. They were everywhere: on the shelves and the table, in the dishes and in the food. I tried various solutions, but they helped for a short time.The product was very easy to setup and the results are great. I just plugged in this device and I could see a huge reduction in flys and mosquitoes. This is a environment friendly electric pest repeller is 100% safe and effective, get rid of pest without killing them. This mosquito repellent is great replacement for mouse trap, roach killer, spray, and baits. The ultrasonic pest repeller covers over 800-1200sq.ft, widely used for households. I am very happy with this purchase no more bugs and mosquitoes and fly I recommend it.

I've had these plugged in for 17 days and I have noticed a decrease in the amount of mice I see. They're not completely gone but it's definitely better..I have a a total of 11 rooms between the 1st/2nd floors and the attic/basement. I put two on each floor minus the basement. May purchase more so I can have one in each room.

I was excited to test this out because I live in South Florida, and having insects in the house is just a way of life. I live in a small space so I only needed to use three of these devices (six come in the box!) There is a power outlet right at my backdoor, which doesn't seal perfectly and is a common entry-point of little pests to my house, so I have been watching that area most carefully. Last week there was a little trail of ants coming in that door--this week they have vanished! I read that I can take up to four weeks for these to have their full effect, but it's only been a week and I'm already impressed.I would make two requests for future designs: a version with a much smaller LED light or no light at all, and a version with a much larger LED light that can double as a night-light!

These are useless in Australia because they have American electric connectors.
