MouseBlocker Prox Plug-in Rodent Deterrent | Professional-grade protection for garages, workshops, RV storage, and vehicles.

Absolutely fantastic product! I've purchased two Prox 120V Plug-in Ultrasonic Mouse and Rodent Deterrents with Dual Strobing LEDs for my vehicle. When I recently needed to swap one out (due to my own issue), I was truly impressed with the exceptional support from Matt at MouseBlocker. He responded quickly and went above and beyond to answer all my questions — rare customer service nowadays! The MouseBlocker has been a game-changer. It works flawlessly and gives me peace of mind. The quality of the product and the support team behind it are outstanding. If you need a reliable device, this is the one! Quick story: living on a wooded lot, we often deal with critters getting into trouble. Before purchasing the MouseBlocker PRO 120V Plug-in, I had over $8,000 in damages—more than $6,000 to my Mercedes and $2,000 to my Ram truck—from mice! I was tempted to buy an old clunker just to drive around and get mice to destroy it, but instead, I bought the MouseBlocker, and I love it! I highly recommend the MouseBlocker PRO 120V Plug-in to anyone seeking a durable and effective solution. Great product, great support—highly satisfied! Thanks, Matt and the MouseBlocker team!

THIS HAS LASTED OUTDOORS FOR QUITE A LONG TIME. USING BAIT BOXES TOO. SO TO REVIEW AS SUCCESSFUL QUESTIONABLE. IF RATS ARE STAYING AWAY MAY BE THAT THEY DON’T SURVIVE. UPDATE 12-05-25❗️ THIS ITEM STOPPED WORKING❗️NO SOUND, NO LIGHTS❗️ WORKED ABOUT 10 Months. Would not buy again

Works great, been using it now for two years and as long as we remember to plug it in so far no more issues with mice!

Seems to help. I'm not giving 5 stars just because I cannot be absolutely certain of direct effect, but we certainly have not had the level of activity around the car we used to see before we set this up. We just let it run in the carport. We suspect the flashing light at night has more to do with the deterrent than the slight sound but don't really know. Our non-scientific opinion is that it has actually helped though.

Great product! No sign of rodents in my vehicle engine bay after previously having a big problem with that. Even parking outside all year round in a rural area, MouseBlocker gives peace of mind. The company is even better! When I had an issue after the warranty had passed, I contacted the company. They sent me a free replacement even though it was out of warranty. EXCELLENT customer service!!! Thank you MouseBlocker!!!

Don't waste your money on Mouse Blocker. I bought two for 99.00 each and it's now 10/29/2025 and they stopped working. I've reached out to Mouse Blocker on why these items only last about 1 1/2 months. They, Mouse Blocker, didn't respond, totally unsatisfactory! My advice if you're considering buying Mouse Blocker is DON'T.

Works great! I was skeptical about it at first but was pleasantly surprised. Within days there was no more scratching sounds. Definitely worth the money

THIS PROCUCT IS VERY GOOD EXCEPT IS STOPPED WORKING AFTER ONE WEEK OF USE. I GOT ANOTHER ONE FOR ITS HIGHLY EFFECTIVE AND HOPE IS WILL WORK BETTER I WOULD LIKE A REFUND ON MY FIRST ONE
