I don't think it would hurt. I prefer the pellets myself but I have a special situation, there is only one spot a rabbit can get through the fence. I sprinkle the pellets outside the fence at that point and it works for us, the dog stays inside the yard unless he is on the leash. The spray just has to be applied more often. It says something like once a month on the label but it was more like once a week where we have torrential rains.
