We use one in our pole building to keep the barn swallows from building nests. It seems to work.

I have had 2 of the riddex one. They both finally wore out, They worked for a long time. When we moved into this trailer home we had all kinds of mice. After I got them I never saw another one.

I never wanted to try them because I have a little fox terrier with incredible hearing. Don't want to risk her hearing it.. The reviews seem to be hit and miss. We had a question about them here in the past it may come up if you search kt for it.

I don't have any pets, but I can understand where that might be a problem for them. I'll do a search on KT to see if I can find it. Thanks!!

Be gardening, I am going to look for the riddex ones when I go shopping in a day or so.

Ravencajun, In one post I found, they used peppermint oil and claim it works well so I will pick up some of that also! :)

Quite some time ago, when I was renting a house, my landlord put them in. The electric pest repellents. It was awful! It was like walking around in a thunderclap. All the hairs on my legs (the follicles?) stood up, and I felt like I couldn't breathe right. He took them out after I complained, and popped for the pest control company to close all the gaps.

A mouse can get into any gap that's as thick as a pencil. Actually, even thinner than that. More like a fluffy, uncompacted, Q-Tip. They're Limbo dance champions and can just flatten themselves and wriggle. It might not be practical for you, but if you can't find and fix the gaps yourself, it might be worth getting a pro in.

I ordered mine from the internet. I don't even know if I have ever seen them in the stores. I had a cat for a while and it didn't bother her.

I've used them for years. When they finally give up the ghost, I replace them. They do drive out and keep out rodents. My bigger concern was spiders. Still get an occasional creepy crawly, but nothing like in the past.

As for pets, I do not know why, but they are not effected. My dog was blind and over 10 years old. She didn't need anything that would upset her hearing. She was totally comfortable around them.

As to how I know rodents don't like them, our well pump is out in an open field. The minute the weather started to turn cold, the field mice would set up a tent-city in the pump house. They would chow down on the wires. PITA! Saw the pest repellers on TV shopping channel 20 or so years ago. Have never been without them since then.

Peanut butter and old fashioned mouse traps work every time. Perhaps the trick is the place them near where they come in? We have several placed around the basement., in the furnace room, in a ceiling on the side of the house that apparently allows access. No critters upstairs!! From your subject line I thought you were asking about those mosquito contraptions that spurt CO2 and NO they do not work. We field tested two of them back when they were "new"..$1500 worth of CRAP.

I have seen them before maybe in Home Depot but will look again for them. I still haven't caught anything. Wish they still sold the D-Con in the cardboard container as then you could tell if they were eating it. I bought one of the new round containers where you put the block of bait on a center post, then close and twist it......can't tell if they are "taking the bait" or not. Thanks for all of the suggestions!

I jog past a house that has an electronic "noise". It's trying to repel something. lol I use a live trap in the attic.
