Seems to be working
Too early to make a definitive evaluation but seems to be working as long as you spread their granules evenly

Sometimes worth paying a few dollars more.
Would RecommendI was going to get the less expensive Preen, but another customer saw that I was & said this one worked better. So far he was right.
