Riddex Sonic Plus Ultrasonic Pest Repeller, Plugs in with extra Outlets Indoor Use - Insect Repellent - Bug Repellents for Home Defense - Protect Against Rodents & Insects, Chemical Free(3 Pack Black)

Hard to say if these sonic repellers work or not for sure. From my experience, we were having a mouse problem for a couple of months. These mice were so brave, they would come into my bedroom and look for food although there was none. Mouse traps were setup but for the 1st month didn't catch a single one.After we discovered the we had a mouse issue (mouse poo, food wrappers opened, etc) we started to clamp down on their food.During phase 1, we kept food on our kitchen table for awhile until we found out that there was a nearby plant that they climbed up and then leaped on to the chairs and onto the table. If there were bags on the chairs they could climb up that as well. Read that mice can jump up to 18 inches. Got rid of the plant and stopped hanging bags or clothes on our chairs.Phase 2 - put all our food not in the covers into plastic bins. Worked but we didn't realize we had other sources of food lying around in the house such as goody bags and such.Phase 3 - scoured the house and got rid of all other food sources.Now with the food sources mostly secured after about 1.5 months, we caught two mice. We didn't know how many mice were in the house but we suspected quite a few. We knew they were living in the garage awhile and migrated upstairs.With the food secured, we experienced the worse mouse violation of human rights. They found a way into our refrigerator!!!! DISGUSTING!!! So next day, I duct tape all possible holes inside that I think they could be coming in from. And to my shock, the next morning, found evidence of mouse poo inside again. Did a closer inspection and found that the rubber seal on the bottom of the refrigerator was broken - had to be their source of entry (even if so small). Well duct taped the seal back on and surrounded the refrigerator with a moat of glue traps.About the same time received these sonic repellers - plugged two of them in the house and one in the garage. Caught one more mouse in the moat surrounding the frig. And after plugging in the 3 repellers and catching that 3rd mouse have not heard a peep upstairs from the mice although we almost heard them nightly. Pretty sure we have more mice in the garage that could have come upstairs too if they wanted to.So from my experience the repellers seem to work. But could it be too that we finally cleaned up all of our sources to rid the mice including maybe catching their 3 main scouts? Can't tell for sure but it's been a week now and I haven't heard a peep from the mice.

These work very well. I have no pests in my home of 2 dogs and 5 cats. No fleas, no mess, no bother. Just plug them in and let them do the work

We had three of these plugged in throughout our home over the course of about a year, and we have just as many bugs and spiders in our house as we did before. Later I read that most insects don't have ears and cannot hear anything, let alone high frequency sounds. So how could this work? Waist of money!"Ultrasonic pest repellers are a hoax and have fooled many unsuspecting consumers. While they seem like a nice family- and pet-safe solution to traditional pest control methods, they are a scam; which is a bummer because the idea of them sounds great.A few studies have shown success with specific insects, such as crickets. However, this success was usually very localized. For example, the pests might have avoided the one particular room where the electronic pest repeller was located, but they did not evacuate the entire house. There has been no proven success on cockroaches, ants, spiders or rodents."

After a bad neighbor moved in next door, rats became a problem, and I have tried just about everything. Poison bait didn't work, sticky traps did when placed correctly, but our dogs sometimes got stuck as well, not to mention personally I thought the sticky traps were cruel. Snap traps, again dogs. My dad found these online and wanted to give it a try because of field mice on his ranch. He said they worked and so I gave them a try. 1DAY!!! I may have gone a little overboard using 6 for a 1200 sq ft home when they supposedly work 1 at 1000 ft, but I don't care. They worked! I don't even hear them in the walls. I cannot explain just how much of a relief it is!

One of the three didn’t work at all!! The other ones are great!!!

The product has kept my house rodent-free for years. Nothing wrong with the product at all.Amazon’s delivery, on the other hand, is aggravatingly bad about half the time. I have clear delivery instructions on my profile. I also have a doormat that points to exactly where packages are to be left. I also have a sign in the spot that says leave the deliveries here. Half the time the delivery people pay absolutely no attention to any of this. And they just drop them in front of my front door, where they can easily be seen from the street, and stolen. That has started to happen. I’m not asking them to even take one step in another direction. Just, instead of leaving the packages in front of my door, to turn to the right and drop them behind a large planter. No amount of communication with customer service does any permanent good. It’s almost as if the delivery people are deliberately ignoring my instructions to prove something. Don’t ask me what that is.Anyway, five star rating for the product. One star rating for Amazon’s delivery. It is a source of consistent aggravation.

I love the Ridex Pest control. Bugs may come in but before to long they are dead.
