So far these seem to be working for ants and rodents but it is still early in the season. I placed these on my patio (2) and in the kitchen (2).
1. Last year I had severe ant infestation in my house. Last fall, I sprayed entrance points outside the house and they have not returned so far. Some ants are on the patio but it is just a few. Previously there were constantly trails of ants. I'd kill them with non toxic poison but they kept coming back.
2. Before I put the devices on the patio, I saw and heard a family of mice in my cedar pine trees. I have not heard or seen them since that night.
At this point I would endorse this product.
This product does not appear to affect my pet rabbit. He sleeps near them frequently.
