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.

I bought this to deter chipmunks from coming in my covered patio. It appears to do nothing. I still see feces and urine in my patio. The test alarm works and a red light blinks indicates it should be working however it is not stopping then from coming in.

Was afraid to use because of my pet bird. Gave to a friend with rat problem, says it works great!

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.

It seems this product is not worked for the squirrels near my house. I put this item in my attic because my roof was damaged by squirrels and these animals went into there everyday, so I bought this device for repelling. I found that, the squirrels keep coming everyday after I put the device in the attic, and one times I saw that a squirrel standing around 6 feet away from this device, it seems it was not scared. Maybe it is work for other animals. If anyone wish to repel squirrels, I don't recommend this device.

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

I was skeptical but am now a believer! I needed to keep mice out of my attic. Traps didn't work. I didn't know how they were getting in either. This was great because it was battery operated-there are no electric outlets in my attic. After 2 days, no more mice! I haven't seen or heard anything since. I don't write a lot of reviews but I was very impressed with this product 👏

Doesn't work on mice in our camper. They walk right over it. Waste of money 💰 Gave it a one star since there's no option for minus stars.
