Nature’s MACE Deer & Rabbit Mace 40oz Concentrate Deer & Rabbit Repellent, Deer Repellent Spray for Plants, Lawns, Flowers & Gardens, Plant Safe Deer Spray, Protect Plants Fast, All-Season Protection

I've used this for several years now with great results, so I decided to write a review after my third bottle. I was skeptical at first. My neighborhood is full of deer and hostas are their delicacy, except in my yard. I have the only surviving and mature flowering hostas in the neighborhood over the last 5 years! One should spray twice within a week in early spring, and then every 3-4 weeks after. It seems that the early spraying lets the plants absorb the components thoroughly after the winter, and then the other spraying keeps the repellent absorbed into the plants. I watched deer after a heavy rain come and nibble on the hostas before I had a chance to respray them, but they quickly moved on after a single bite.OTHER THINGS TO KNOW: The concentrate is a lot less expensive than most of the other competitive products, and I mix it at 10oz./gal (2.5oz./quart) for optimum results. It keeps away rabbits most of the time too, as they used to be the critters that would get my plants next to the house. The minty smell is pleasant, but also has the egg base and garlic in it for maximum effectiveness. It claims to be safe for vegetables, but in my opinion I won't spray directly on forming beans, corn, peas, peppers, or other vegetables in case the scent or egg base is absorbed into the edibles. I thought to try "Liquid Fence" or "Deer Out", but Liquid Fence is egg based, smells bad, and not recommended for vegetables, and "Deer Out" is mint based (ok for vegetables), but it was reported to not be effective after rain. But "Deer Mace" is the best of both of these other products (eggs, garlic, and mint) and a lot less money, so this is the clear choice due to the demonstrated results!Update 1: There is no reason why some may say "Liquid Fence" or "Deer Out" is better, since they both have mostly similar ingredients, but the Deer Mace concentrate is less expensive with higher concentrations of active ingredients and better after-rain performance. The suspended solids spray may clog using a trigger sprayer bottle at the higher concentration I use, so I switched to a handheld Agricas pressurized sprayer with better results and no clogging. One would do well to add an extra amount of a liquid dish soap to each ready-to-use batch for even better dispersion, absorption, and clinginess to plant leaves.Update 7-23-24: I'm on the subscribe and save for this product. I created a spreadsheet for popular deer products with their active ingredients and concentrations. This product combines the minty smell with the egg based component, where others either use one or the other, except for the blood based products. I was not impressed with the results to keep away rabbits as of late. After I thoroughly sprayed the hostas, the first two pictures show where the rabbits have nibbled on part of them. The third picture shows some of the unharmed hostas with flower blooms next to the heavily populated deer woods. Thus, even though my hostas survive the deer, the rabbits are still nibbling on those close to the house. 2 star for rabbit control but 5+ star for deer!

Firstly let me start by saying that the bot you use for feedback is impatient. You need a bit of time to see if the product is going to work! That being said, it’s been three weeks since I first applied the product. I’ve re applied twice since the initial application because I was nervous about it’s effect through the torrential downpours we have had here in Pennsylvania. Here are my findings.DisclosureI have a one acre cleared lot in the middle of an 11 acre property. I have A LOT of deer.The smell:Compared to other products I have used this is the least offensive product in terms of smell. The primary smell upon opening the product was mint, not the sulfur smell that most other products omit. Realizing that made me confident enough to mix in my kitchen.After applying the product to my affected plants, I could smell the mint in my garden. This to me was not offensive either as I underplant with a lot of varieties that have a mint scent ( Agastache, Nepeta.) in hopes the herds of deer on my property would keep away. I have found that deer are as selective to plants as children are to hidden candy in a pantry stocked with healthy snacks.Use:I applied the product as directed on the label. Without looking I believe it’s 8oz of product to a gallon of water. I used a garden sprayer to apply the product. The product was easy to use and did not clog my sprayer. The night the first application, it rained. After it dried I could still faintly smell the mint on the treated plants so I waited a day or two to apply it again.ConclusionThe proof is in the pictures. I have extensive deer damage. Especially my hydrangea and sedum. You can see from the above photos despite the damage there is a lot of new growth on the plants. This gives me hope that with continued use of the product I may even actually get blooms. More to come as with positive (or negative) results I will be looking to update this review. For now, I can say buy the product with confidence.

Definitely a very effective product. We moved to a house with some gorgeous hosta last year. They were gorgeous one day and gone the next. The deer ate them down to the nubs overnight. A friend recommended this product and to my delight the deer haven’t touched the hosta this year. My only issue it the smell of the stuff. It says it smells like mint, I think it smells like rotting garbage. I opened the package in the house and had to immediately take it outdoors. It is also oily so would recommend wearing gloves while mixing. Would recommend the product but not for plants in an area close to where you spend a lot of time. It STINKS!!!
