Zahav Ultrasonic Pest Repeller Plug in, Pest Reject Electronic Control for Mice Insects Rodents Bed Bugs Mosquitos Flies Spiders Cockroach & Rats, Human & Pet Safe Non-Toxic (6 Pack)

It is hard to give an accurate review at this time. Because it is winter here in Erie, Pa there are not a lot of pests. I haven't seen any insects to date but I will need to see in the spring when we get ants. If we don't get them, then I can assume that they are working as described. I will update this review in the spring.

So far have seen a decrease in flies, there is still too much to my liking? Don’t know if I have to give it more times?However increased in fruit flies?

I HAVE THEM PLUG INTO THE ELECTRIC OUTLET I HAVE SAW 1OR 2 MICE TONIGHT HOW MANY FEET DOES THE ULTRA SOUND SEND?

Long but worth the read! I had a big roach problem in my ranch and I was looking for solutions other than pesticides and an exterminator...after doing research and trying to find a safe solution, I stumbled upon these pest repellers on amazon. I cant tell you guys enough how much these things saved me time and money. I plugged them and after just a few days the roaches were slowly disappearing. I have a 2 year old and dog so these repellers were the best non pesticide solution for me. I had my doubts because of some reviews about this product in general but I thought if these things really work, they would be worth every penny and sure enough they were. Its now been 2 months since I first got these and the roaches are completely gone. I really believe this product can help many people. Im going to order one more for my office at the start of summer. Highly recommended product!!!

Have a rather large kitchen. have 6 units in that room alone. does not work at all. no decrease of pests since they were unstalled on Aug. 17th. will wait a little longer. will change review if pests lessen. but standing rather firm with review right this minute.

I live in the south and we have so many crickets here and random bugs, especially since we live close to the woods. It was causing so many issues in our basement and near our front door that I was looking into different ways to fix it. However, nothing was fixing it. My friend recommended this and I decided to give it a try. It worked like a charm! Second day now and I've saw no more random bugs, especially crickets! I also haven't saw any dead bugs either, which shows this is working great. As long as it keeps the bugs gone like this for a while, I'm happy.It's extremely easy to use as well, and doesn't stand out. I'm really glad this was recommended to me, and would recommend it myself.

I honestly did not see much of a difference. We got them for feildmice..

I just got these a few days ago and they are already working great! i plugged one in my basement where i had a bunch of spiders with babies and i came back to check on them the next day and the mothers were nowhere to be found. I guess they left their babies because of the ultrasonic sound. These things actually work. The description say it takes 3-4 weeks for full results but i guess i got lucky with just a few days. i plugged in the rest of them around my house, and i have no doubt they'll do their job. Its also a nice little design with a small blue light which is pretty cool. i don't have prime but these things got to me within 2 days anyway! Great product, recommended!
