Concentrated Deer Repellent - Bobbex | Deer, Elk, and Moose Deterrent Concentrate (64 oz.) UB-U9NT-KE8U

We have a serious deer problem in our flower beds. Have been using this product for several years and it works like a charm. Product says to spray once every 30 days on susceptible plants - in my garden it's day lillies and hostas - but during blooming season, we spray every two weeks and the deer just walk on by!

This stuff does the job. I'll warn you that it stinks, but that's why the deer hate it. We have 28 arborvitae on each side of our yard that would be eaten up by the deer if not for this Bobbex deer repellant. It makes enough to spray our arborvitae 2x over the late fall & winter months.

It's about the only stuff that works! I NEVER see deer eating my hostas any more WHEN I USE IT. To be clear: This stuff, when mixed and applied correctly is PERFECT...NO DEER or varmints go near my hosta plants. UNTIL IT RAINS! I forgot to apply it for two days after rain and the deer DID show up and ate a few plants. BUT....as soon as the rain stopped I reapplied it and POOF! Gone again the deer are....not a bite taken. I live in NW PA and we get lots of rain, but I run out after every rain and spray. Otherwise I've gone TWO WEEKS (again, when there's NO rain), and not a bite is taken off any plant. I've tried them all and THIS is the only stinky brew that works. I sprayed it in my eye accidentally when my old sprayer broke..It burns and I STUNK! But that's it. I do manage to spill it on myself or a bit on the garage floor and it stinks. But then I have animals in my garage now, either! Bada-bing, bada-boom...best stuff ever. I started with a 64oz last summer, this year (2025) it's 2.5 gallons, baby. Well worth it.

I was so skeptical about this product, especially since they say it won't wash off, giving one the idea you only need to spray once, or once every month or two. However, we've had to spray once every week-- not because the spray washed off, but because the deer started eating the new growth and new blooms that hadn't been sprayed. This stuff stinks. Really bad. Do not stand downwind while spraying-- you don't want this on your clothes or person. In fact, don't stand downwind from it (or anywhere close for that matter) for about 12-24 hours after spraying. But for all the stink, it works! We have some encore azaleas that a few years ago stopped blooming. Or so we thought. We also thought deer didn't like azaleas. Wrong. At first they only ate the blooms, so we'd see buds, but then no blooms. Seventeen encore azaleas just stopped blooming-- although the 20 non-encore azaleas continued to bloom outrageously. Finally the buggers began eating the leaves too, and then we realized what we were dealing with-- hungry deer. We have sprayed our encore azaleas 3 times in the past 3 weeks. I had forgotten the color of the blooms of some of our azaleas because it had been so long since we'd seen them! The 3 newest plants, purchased 2 years ago and almost eaten to death, are finally being allowed to gain new growth as the deer are leaving them alone. We'd pretty much written them off as deer food. Bobbex doesn't say their product will work with rabbits, but I've got some eating my newly planted petunias and we decided to spray them today just to see if it helps. I'll report back if it does. Fingers crossed. [EDIT: Bobbex DID work on the petunias! The rabbits hate it!]

It works great.

This stuff kept all the deer and elk off my property. Not even my sheepnwould go near my arborvitae plants.

I can see why it repels deer, because I can’t imagine it not repelling anything with a nose. It’s like concentrated rotten onion stink the second you open the jug, and I gagged the whole way through application. I will update with how long it takes for the smell to dissipate, but for at least today I will not be going onto my porch or opening my front windows.

Update June 2016 - Product became ineffective after using for a few years. Dear got use to it and would find what I sprayed and eat it. Most recently was 6/26 and they ate the lilies the same night i sprayed them with almost double the concentrate/ I even ensured they where coated to try and save them. Obviously nothing is fool proof so have to find a new spray without the same stink to throw off the deer... Old review below It is also probably the smelliest product I have used, really it stinks but not like that. It is also not to be sprayed when the windows are wide open on a sunny day taking in the lovely weather, according to the family that is :-) I have fought a losing battle for years now with my Day Lilies, White Lilies and Star Lilies losing each year. But this year we enjoyed almost all of the Lilies. I say almost all since in a heavy Dear area, which I have, they will sample a few plants before realizing it is yucky and move on. The Hydrangeas and Azaleas all got to bloom much more this year than any other also. And the Hostas where not the usual salad buffet like years past. They are correct in that you need to spray regularly in the growing season for fast growing plants and every 10-14 days, based on rain for, the others. But they are also correct in that it does not wash off easily, due to the Fish Oil, and it does provide superior protection when compared to all the other products I have used. Those products include everything Lowes and Home Depot sell, plus a few blood products from Amazon. I also tried the systemic pepper tablets, but they seem to work indifferently and if I did not spray then the plants got eaten - seems the deer like a little spice in their food but not this smelly stuff. So if you have a strong stomach this could be the product for you..
