Repel-It Ultrasonic Pest Repeller Plug In, Dual-Technology Pest Control (5,000 sq ft) For Mice, Rats, Cockroaches, Spiders, Ants & Insects. (4 Pack - Full House Coverage)

I lived in my house for many years with no spider problem. After about 5 years I finally decided to hook up a 7.2 surround sound system for watching big box office action movies. I wanted lots of bass to mimic movie theaters, so I also installed two twelve inch subwoofers, but to be considerate to my neighbors, never to be used before 12 noon or after 8 PM =^). I was watching only about 3 to 4 movies a week with the subwoofers, and never used them for music. Then within only a few days the spiders started appearing in my house. I went from seeing about 2 spiders a month (before I hooked up the subwoofers) to about 3 to 4 spiders a day. I then did some internet research, and sadly I learned that spiders are greatly attracted to vibration, which is exactly what subwoofers are made to do. Ants also started to come, but no nearly as often as the spiders. Sadly I decided to stop using my subwoofers, (because I hate finding spiders in my house more) and switched over to using a good pair of high quality headphones. Now… my problem was getting rid of the many spiders that now felt that my home was now their new home, and just because the subwoofers had stopped, they were not leaving, but now starting to breed. For like three or four straight months, I tried repeatedly house bombings, and using all kinds of dangerous bug sprays, powders, exotic oils, and nothing was getting rid of these spiders ( the majority of them anyway) until I finally bought these. I installed 8 throughout my house, (about 1200 square feet) and to my greatest surprise, they also got completely rid of my front and back yard moles. I was averaging removing about 4 moles a week before I installed these. And back to the spiders, I average finding only about 1 to 2 per month now, and never the big ones anymore. No one has paid me or given me anything for this review. I just hope that this review can help others, to understand that their sound system may be the main problem if they are also experiencing a high spider or insect invasion. I have overall purchased around 4 or 5 boxes of these for myself and other family members, so you may see multiple reviews that I have written on these over the last 6 months. Each of my newer reviews give additional insight that may not have been covered previously.3/26/2018 UPDATE!LOW FREQUENCY SOUNDS (MADE BY SUBWOOFERS) ATTRACTS SPIDERS EVEN MUCH MORE THEN THE VIBRATION.

After extensive research, I decided to get these over the rest and couldn't be happier! I do not know why there are mixed reviews as it does what it's supposed to. Within 1 hour of plugging into an outlet in the kitchen I found 2 flies writhing on their backs on the counter. I could not believe it as I have never seen a fly do this. I got a paper towel and grabbed both and disposed of them. The next day in the entryway I found a large cockroach just standing there near the outlet where I plugged another one. When I saw it I gasped as it was large and disgusting and it never moved. I had time to go in the kitchen grab my gloves and paper towel and dispose of it. It never moved and it was alive when I grabbed it, gross. So with that, I am truly happy with the results and it's only been 4 days. Not a creature in sight and to all a goodnight, lol.

I've only had it for a few days but it seems to be working.

Love the product. Easy to install and now we have a peace of mind. Looks nice too!

I've purchased a few of these and placed around my home and have not seen an insect since! They worked so good within the home that I purchased more for the garage and upstairs. Now, I have 360 degrees of coverage and so far, so good, no pests. The only problem that I had prior to purchasing these repellents was ants on a windowsill. I was constantly spraying insecticide to get rid of them. But now, I've only seen a few and they were dead. I placed them upstairs a week ago and when I went to check a few days later, there was a big water bug, similar to a big cockroach, on the floor just staring at me. Immediately, I went downstairs and got the insecticide sprayer and broom, but to my surprise it was still in the same spot when I returned and it wasn't moving but was dead. So, this product is amazing so far and if in the future I discover that it isn't working I will definitely update my post. But until then, I HIGHLY recommend this product!

Had spiders on my garage for 15 years could never get rid of them. Yesterday i saw one. saw none at all today. that is in only 5 days. It is more than i expected. never thought it would work that good.

Please see the video.A week a go, my wife told me that she had seen a mouse in the washing machine’s room inside the kitchen. I have looked all the day long without seen any trace of mice. Then I tested the room and placed a piece of cheese nearby the washing machine before going to bed. Next day early in the morning, the piece of cheese had been disappeared!. Yes Sir, certainly, the wife was quite right. I retested the place again for confirmation, and the cheese disappeared again and again.Well, I have to setup a plan in order to catch this litter rowdy creature.First of all, I need to see his trace (faeces) to determine how big is he. I moved the washing machine a little bit to see underneath and I found a lot of traces. Oh boy! This RAT is quite big, he is as big as a little kitten; so, glue won’t be able to catch him. Then, I converted to Plan B.I used two methods to grasp him in the cage. The Electromagnetic & Ultrasonic device imposed him to get out from under the washing machine, and the Hunger directed him towards the food (cheese) inside the cage.Please see the video.

Purchased to replace a black and decker unit that was making noise. The next morning had a spider in the tub that was very agitated. Seams to be working as advertised.
