I have used this product regularly as I live in an area where there are a lot of sheep and deer. I have never seen fleas on my dog since using this, and it also kills of the tick when attached to the dog. I would highly recommend using this product.
I saw this advertised an thought it would be an ideal edge for my garden. I was surprised at the quality of the item as I expected it to be more sturdy. Upon using product, it buckled when put together.
