PestContro Portable Ultrasonic Rodent Repeller, Cordless Non-Lethal Pest Control, Dual Frequency, Mice Rats Squirrels Chipmunks Kitchen Office Garage Basement Shed Storage Attic

I live in a manufactured home on a concrete slab with a crawl space underneath. I was hearing random sporadic scratching & scurrying under my bathtub and bathroom floor off and on for weeks, then it became every night & sometimes during the day so I was sure then it was either a mouse or chipmunk/squirrel and it was not going anywhere. I figured before I call someone & spend $ let me try a couple of cheap options first. My grandmother used to use devices like this so i thought I'd try this 1st. I didn't want to put it under the house first just bc it would be easier if I could figure out a way to keep it inside to monitor it & have it still work. Although it said it doesn't work thru walls, I wanted to try maybe thru the floor/bathtub. I found out by accident that it would work inside another way! I had it aimed at the drain in my shower at night to see if that would work - well 1 morning my son turned on the shower & got it soaked & he put it on top of the floor air vent to dry out. While I was outside I heard this ear piercing noise & it was coming from UNDER MY HOUSE! I ran inside & found it was in audible mode bc the batteries were wet & because it was aimed down on top of the floor vent it was echoing thru all the air ducts under the house!!!! I shut it off, took the batteries out, let it dry. Once it dried out, it worked normal again (silently but flashing light every few seconds with small audible beep). I kept it face down on top of the floor vent, hoping it would reverberate thru all the air ducts again and within 2-3 weeks whatever rodent was under there previously was GONE!!!! I have not heard 1 scratch! Not 1 little sound AT ALL SINCE!!!! I keep it face down on the vent & not 1 problem since. I can't believe it actually works AND I am able to keep it inside the house to monitor when it needs the batteries replaced. It has been several months & no issues. For the money and the ease of use, it is beyond well worth it! Beats having to hire someone to go under my house & charge me $$ to eradicate & probably maintenance! I know some people say it didn't work for them & I can imagine it may not work for every situation - I'm sure different factors come into play but for the price and how simple it is, I think it is definitely worth a shot. It definitely took 2-3 weeks for it to drive this pest away so it doesn't work overnight but I have NO COMPLAINTS! I am super happy! If anything changes I will update but as I said it has been several months now & it has remained effective.

Do not buy. This item does not repel mice as promised I put batteries in it and turned it on. Lights flashed in accordance to directions. I used test button and the audible signal worked. To test the effectiveness of unit, I placed it right next to my electronic trap that I use. Lights were blinking every 2 seconds as it says. The night I set it up, TWO mice walked right into trap. Not deterred in the least bit. See photo, ultrasonic unit set next to trap directed at opening. You can see the mice carcass in trap. Do not buy.

Very nice and very good product

Bought this for my off-the-grid cabin as I was needing a battery operated device. I have several other "plug-in" devices at our home and they work very well so I thought this battery operated one will do the trick. It's been in the small one room cabin for a over a month now and the mice just ignore it.Update: Took a lot longer than expected, but cabin is now clear of mice. Note, I have also taken other measures, like dryer sheets and a homemade peppermint essential oil spray. I will however probably order another one to overlap the battery life so there is always one unit working in the cabin at all times now that it is getting colder at the critters are looking for a place to live for the winter.

It worked through various midwest/plains winters but I didn't notice any difference in varmints .

I have two of these. One for my attic and one in my garage. I've never seen a rodent, spider or any kind of bug, insect, animal in my attic since getting this. I just can't believe how expensive it's become. I bought mine on amazon for about $30 each. I'm sure there's other battery operated ones that are cheaper and work just as well.

Works Was away for about a month and left my old pick up truck in the drive. Typically filled with mice on my return. It was really infested before I left. Cleaned it out and put the repeller in the cab. Much to my surprise no mice.I had even left a bag of trash in the bed so this was completely remarkable. I was ready for a typical not working. Seems dinky one red light and a pressable noise tester, but despite that keeps the mice away. Batteries lasting more than a month so far

Dont waste your money!Does NOT work
