Great stuff! I've used it for about ten years. I live on an island with a large herd of deer who leave my plants alone as long as I remember to spray with Deer Off once every three-four months. If I forget, the deer remind me.
Deer Off works great, and does not discolor our hostas. It works for a long time. We do two or three applications per summer. We have a lot of hostas and a lot of deer. So we use the concentrate to get cost effective coverage. Be sure and wash out your sprayer thoroughly after use to avoid clogs. Recommend Deer Off highly.
I have a lot of destructive deer. I've been using this product for several years, and it works. You have to keep your eye on the rain and reapply it if there's been heavy rain, as we've been having frequently on the East coast this year. But I've got daylilies with flowers and hostas with leaves, so it's definitely worth it. Excellent product.
