I love my pest control device. I bought 6 of them. They last up to about 5 years. I've been buying them for years. They actually do work great! Follow the instructions that came with it and give it up to a few weeks to start seeing the results.

I have waited to write this review until now. As I read other reviews on this product as well as other brands the reviews were mixed. I was hesitant to make this purchase but I was desperate. You see, after living in our newly constructed home for 7 to 8 moths we suddenly had an influx of scorpions. Now if you have ever had a run in with one of these you know they are like the spawn of satin! I sprayed and tried all of the other tricks I found on the Internet. Nothing worked.I decided to take the risk and purchased 3 of these. I placed one in the garage and two in the house. We had 2 to 4 scorpions per day for over a week prior to installing these. After the first day of use we found one scorpion in the garage. But after that one, there has not been anymore. There has been a reduction in crickets as well, which scorpions feed on. We still have some small spiders, ants and a few other pests show up from time to time but their presence has been reduced as well.The main reason I purchased these was for the scorpions and these absolutely worked on them. It was money well spent.No one electronic pest control can stop all pests. Consumer Reports says each brand works on its own frequency or by other means. So you need to find one that works for what your problem pest it. If your problem is scorpions then you want to get this one. Again, I purchased 3, putting two in the house and 1 in the garage. They were worth every penny as our scorpion problem is gone.

Does not work on tiny black "oderous house ants". It looks cool, and it may be working on other pests (can't tell as I had not had any other pest issues) but it's been 2 weeks since I installed it in my newly acquired (older) house and I still get the ants crawling across my desk and kitchen sink. I am meticulously clean so its just a matter of the device not repelling their curiosity. Too bad. I really like cool tech and from other reviews this appeared to be the answer to my problems. If you also have tiny black ant invasions, don't buy this device; it doesn't work.UPDATE 06-13-18: I've revised my rating from 2 stars. The ants, being so small, must have taken longer to all come out of the walls. Its been over a week now and I have not seen one ant, or any other pest for that matter. If this keeps up I will update this review again in a couple of weeks.UPDATE 07-04-18: I've revised my rating from 4 to 3 stars. The ants invaded my office today, after 3 weeks of not seeing any. But, I had the single unit plugged into the center area of my 70' long house, so it was ~35' from it to where they were showing up in my office, and there were walls in between. I moved it to my office and immediately started seeing the ants immobilized and dying. I am rating this "okay" because the initial specs online are misleading about range and penetration issues. The manual, after you buy it, says: "The ultrasonic sound emitted ... can travel up to 5,000 sq ft in an open area (such as a warehouse), however the sound will not penetrate solid barriers." In other words (which should have been stated up front) one pretty much needs a unit in every room where there is an infestation. The manual also says: "For optimum coverage, plug a unit in each room without anything blocking or covering the device." FYI for those reading this.UPDATE 07-20-18: I've revised my rating from 3 to 1 star. The ants are back. I have 2 units now: one plugged in 8 feet away from my desk, and one plugged in 2 feet away from my kitchen sink, right above it. And yet, I still find them crawling across my desk (right in front of me) and around my kitchen sink. It's like they just decided to get over it and have become accustomed to the annoyance, and are shrugging it off. Either it's this brand, or it's this tech that appears to be totally useless against tiny black ants.

This thing is worth the investment. It has noticeably reduced bugs in our house by more than 50%. That's a big difference. We would usually find 1-2 bugs a week, now we find 1-2 per month. And that is consistently over a year, so it wasn't just a seasonal change. We have 2 of these installed, one on each side of the house. This should be viewed as one tool in your bug control arsenal, not a total solution. Still need to spray for the remaining bugs, but definitely a noticeable reduction.Note: You will want to do a heavy spray right before you install these. Since it drives bugs crazy, we actually noticed an increase in bugs for the first couple weeks, because they were all running around trying to get away.

Doesn’t stop bugs

The night light, all by itself, is wonderful. The sonar thing seems to work - except for spiders, which I sometimes see calmly sitting on top of the unit. Great for dark corners, for indoor walls that face the outdoors,)this is not an outdoor unit). I wouldn't be without a couple in my kitchen. Have been buying these for years. In my opinion, the smaller ones are more convenient, but I no longer see them on Amazon. Anyway, I'm happy w/ these and plan to keep buying them every couple of years, rotate the old ones out, keep the new ones (and I mark the dates purchased - just to keep track.)

I have purchased this product from several different online sites over the years. Lately, through Amazon I have been putting it in all the rooms. Not only is the entire purchase and shipping process faster and safer, they have the best price, THANK YOU. There is no 100% effective product that will kill all the pests in our homes. I give it an 85% effectiveness. It has been easily tolerated by my pets except those that belong to the rodent family such as hamsters and rabbits. It is not necessary to use harmful chemicals (for humans, animals or that contaminate the earth) and in my experience it is effective for more years than the seller claims. I consider it my first option to keep pests out of my home and have recommended it to family and friends.
