Pros: Night light, chemical free, silent
Cons: Doesn't keep mice, spiders or squirrels away.
Oh boy, if you're looking at this review in search of an answer for your pest problem, what ever it is, I feel for you.
I purchased this plug in style Pest Offense on line at Walmart to keep away any kind of mice or rats that might come to my house from the construction on the house next door. I was also hoping that this pest offense would keep away squirrels from getting into my attic.
When I saw the description of the item, I read that it would keep away mice and rats and possibly squirrels so I purchased it with high hopes. I also liked that it said it would keep spiders away. We don't have a spider problem but we do get spiders occasionally.
When I recieved it, it didn't come with very much information. Basically it said plug it in and leave it alone. So I did just that.
The product claims to make vibrations in the walls through the electrical wiring already in the house. I did not hear or feel anything happening in the walls.
I placed one on each floor (4 total), the basement, first floor, second floor and finished attic. The product claims only one unit is needed per floor. (This made no sense to me since my electrical wires don't go from one room to the next on the same wiring. Each room is on its own breaker and some rooms have multiple breakers)
Within a week, a squirrel in the attic woke me up. Clearly, it didn't work for squirrels. A few weeks later, we discovered mouse droppings in the basement. There was also no reduction in spiders.
I had been "had", according to my husband. To tell you the truth, I kind of feel like that too. Pest Offense didn't work and I bought several of them!
What I liked about the Pest Offense:
1. The Pest Offense makes a nice glow light/night light.
2. The Pest Offense is quite.
3. Chemical free
What I didn't like:
1. Paying for something that didn't work.
2. The little red and green blinking lights will make you crazy.
3. The Pest Offense is large and guests WILL notice it. Many guests asked me if it was a carbon monoxide detector.
