Love these!! I've told everyone about these! They are wonderful! We put them underneath our hummingbird feeder as the baffles and the soap have done nothing to keep the raccoons and the deer from taking the feeders down. Now, since lying these down, the hummingbirds are drinking comfortably!
We staked them down with wire stakes as the plastic stakes inside the mat didn't hold the mat down. We cut the mat to extend a bit outside the range of the feeder. You can't really see them in the grass but you can definitely feel them. I put pinwheels around d the area so grandchildren are aware of them in the ground.
I bought 3 packages and so glad I did so I would have enough for all of the feeders we have hanging for all the birds.
Definitely a fantastic idea and we love, love this product!!
