Ultrasonic Spider Repellent, 6 Pack Electronic Mouse Repellent Plug in Indoor Harmless to Pets and Human Multi Insect Control for Mosquito Anti Rat Spider Rodent Fly Mosquitoes Mice Cockroach Moth

They work well.

Before using the Ultrasonic Pest Repeller, we were experiencing a regular weekly infestation of spiders and wood roaches in our home, which was causing us considerable distress. Despite our efforts to keep our home clean and tidy, we found that these pests kept returning and were becoming increasingly difficult to control.However, after using the Ultrasonic Pest Repeller, we were pleasantly surprised to find that we had not experienced a single spider or any other pest in our home. The device seems to have been highly effective in repelling these pests, allowing us to enjoy a pest-free home without having to resort to harsh chemicals or other invasive measures.To achieve this level of success, we used the pack of 6 devices that came with the Ultrasonic Pest Repeller. We strategically placed one device in each of our first-floor rooms and one in our attic, covering all the areas where we had seen pests before. We found that the pack of 6 was perfect for our needs, as it allowed us to achieve complete coverage without having to purchase additional devices.We were initially concerned about the ultrasonic sound that the devices emitted. We were worried that the sound would be audible to our children and cause them discomfort or distress. However, we were pleased to find that our children could not hear any of the ultrasonic sound and had no issues with the devices at all.Overall, we are highly satisfied with the effectiveness of the Ultrasonic Pest Repeller and appreciated that it lived up to its claims. We found that it was an easy and convenient way to keep our home free of pests and would highly recommend it to others who are dealing with similar issues.

mice literally next to it and no improvement for 3 weeks

I am absolutely terrified of spiders. Terrified may even be an understatement lol. When we first moved into our new house, right off the bat, we were finding spiders daily. And not the small ones either, we had those huge fast spiders in our basemen were my kid's rooms are, main floor bathroom and of course, my bedroom. We were just going to bug bomb the house but found that to be too difficult since we have two dogs. All the pet friendly alternatives didn't cut it. I bought these and in the first week, we saw a dramatic decrease in spiders. As of today, we have yet to see any spiders or other bugs for that matter. These are perfect for pet friendly houses and for people who don't want to mess with heavy chemicals. These pest resellers don't emit any sounds as far as I can tell either. A must have for pest control!

I have only had this on for three- four days and I have not seen any roaches. I also have boric acid powder around the house, roach trap, and poison. I am not sure of what is working at this point, but I am glad that my house has been free of roaches for three-four days.

So far, so good. Haven't seen any bugs so far, looks like it's working great. Very easy to install.
