If you have arborvitae, you already know the heartbreak: a single hungry deer can shred a mature hedge in one night, leaving bare brown branches where your privacy screen used to be. This guide cuts through the spray-versus-granule debate to find the real solution — the repellent that actually stops deer from treating your trees like a salad bar, based on the ingredients and application data that separate the duds from the serious protectors.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
If repelling deer is a constant battle for your landscape, the right deer repellent for arborvitae is one that combines a proven active ingredient list with a rain-resistant sticker that keeps the barrier on the needles through a week of weather.

How To Choose The Best Deer Repellent for Arborvitae
Arborvitae have soft, dense foliage that deer love, and they are also tall enough that a ground-level granular might not reach the tender new growth at the top. The best defense is a product that physically coats every needle with something the deer find unpalatable and that stays put through dew, irrigation, and rain.
Rainfast Stickers vs. Wash-Off
A “rainfast” formulation (one that has bonded to the leaf surface after it dries) is the single biggest predictor of success on arborvitae. If the product washes off after a light rain, you are back to square one. Look for labels that say “rainfast in 24 hours” or list natural sticking agents — these hold the active ingredients on the waxy arborvitae needles through weather, so you do not have to reapply after every storm.
Liquid Sprays vs. Granular Repellents
Liquid sprays coat every inch of foliage, which matters for arborvitae because deer nibble the tips first. Granular products are sprinkled around the base of the plant and work by creating a scent barrier in the soil. For a tall hedge or mature arborvitae tree, a liquid spray that reaches the top growth is usually more effective. Granulars can work for younger, shorter arborvitae but are better suited as a supplement.
Application Frequency and Timing
Deer pressure is highest in late winter and early spring when natural food is scarce, and again in fall when bucks rub antlers. A good repellent will state a reapplication window: every 2 to 4 weeks during the growing season, and every 3 to 6 months during dormancy. If you have a heavy deer population, you will need the shorter end of that window.

In‑Depth Reviews
1. Deer Out 1 Gallon Concentrate
The rain-resistant concentrate that keeps a tall arborvitae hedge safe with a pleasant mint scent.
For mature arborvitae that are too tall to spray with a hand bottle, this concentrate makes gallon after gallon, and the built-in natural stickers hold the sprayed-on barrier in place through weather. It has a minty fresh scent that deer hate but humans find pleasant, which is a major upgrade over the rotten-egg smell many competitors use. Buyers report it lasts for weeks even on shrubs and fruit trees, and a single application sticks to the plant impressively well.
Unlike the Bobbex, which needs frequent sprayer maintenance, Deer Out’s formula mixes 13 ounces of concentrate per gallon of water without clumping and stays stable in the sprayer. It is the most expensive pick on this list, but for a tall arborvitae privacy screen that you only want to spray every 6 weeks during the growing season, the cost per treated foot is lower than a budget pick that washes off after one rain.
Owners mention that while it reduces damage significantly, a determined deer population may still taste-test occasionally, so netting offers a supplement for truly prized specimens.
Why it wins for arborvitae
- Two natural stickers mean it won’t wash off easily, crucial for waxy arborvitae needles.
- Pleasant minty scent unlike the foul-smelling alternatives.
- Year-round formula works in all seasons, including dormant winter when deer pressure peaks.
The honest trade-off
- Not 100% effective against very hungry or determined deer; some may still test plants.
- Premium price; the concentrate is a higher upfront investment.
Who it serves: Homeowners with established, tall arborvitae hedges who want a pleasant-smelling, rain-resistant solution that lasts weeks per application.
Who might want a different option: Budget-conscious shoppers on a small single shrub may find the upfront cost of the concentrate too high.
2. I Must Garden Deer Repellent Concentrate – 32oz
The professional-grade concentrate that covers 10,000 square feet with a pleasant spice scent.
If you have a large property with multiple arborvitae and other shrubs, this 32-ounce concentrate makes 2.5 gallons of spray and covers 10,000 square feet, giving you the best coverage per dollar on this list. It smells like cloves (ginger and spice) instead of something rotten, and it has natural sticking agents that help it adhere to leaves. Reviewers confirm it seems to last through a couple of rains without needing immediate reapplication, which is a real advantage for arborvitae in a typical spring with showers.
Unlike the Plantskydd, which requires a separate sprayer and can clog, this concentrate mixes easily without clumping and can even be stored after mixing for future use. Compared to the more expensive Deer Out, it is trusted by professional gardeners at public gardens and resorts. It is a mid-range option that outperforms pricier rivals for coverage and rain resistance.
Buyers recommend spraying weekly and after heavy rain for best results, and note it is safe for pollinators once dry.
Smart buy for big yards
- Makes 2.5 gallons and covers 10,000 sq. ft., the most coverage in this comparison.
- Pleasant spice scent (clove/ginger) does not linger or offend.
- Trusted by professional gardeners for over 15 years.
One thing to watch
- Needs drying time before rain to be effective; avoid spraying right before a storm.
- Reapplication needed after heavy or persistent rainfall.
Best fit: Gardeners managing large landscapes with multiple arborvitae beds who want professional-grade performance without the premium price tag.
Not ideal if: You live in an area with daily heavy rain and cannot time your spray window.
3. Plantskydd Animal Repellent – 1.3 Gallon Jug (PS-5L)
The heavy-duty liquid that stays rainfast in 24 hours and protects for months in winter dormancy.
This 1.3-gallon jug is built for the arborvitae owner who wants a low-maintenance solution during the dormant season when deer are hungriest. It protects 500-600 plants at 1 foot high, and the application frequency is generous: every 2-4 weeks in the growing season but every 3-6 months in the dormant season. It is rainfast in just 24 hours, meaning once it dries, a heavy downpour will not wash it off. Customers note it keeps deer away from hostas with just two applications per season in the Midwest, which is impressive endurance.
At 10 pounds, this is the heaviest container in the lineup and significantly heavier than the 2.5-pound EPIC REPELLENTS granular. However, the jug does not come with a spray trigger, so you will need a separate garden sprayer (a Chapin sprayer is a common recommendation from reviewers to avoid clogs). The strong smell during application is unpleasant but fades within a few hours.
Some reviewers point out the formula can clog sprayers if not strained, but when applied correctly it deters a wide range of animals including rabbits, vole, and moose, not just deer.
Where it excels
- Rainfast in only 24 hours — very strong weather resistance.
- Dormant season application lasts 3-6 months, saving winter effort.
- Protects against many herbivores, not just deer.
Before you buy
- No spray trigger included; requires your own sprayer.
- Formula can clog sprayers; best strained or used with a simple bottle.
- Strong odor during application.
Ideal for: Gardeners in cold climates who need a single dormant-season application that lasts a whole winter, and who already own a garden sprayer.
skip it if: You want a ready-to-spray bottle with no extra equipment — the Bobbex is easier to grab and go.
4. Bobbex B550170 Ready to Use Deer Repellent with E-Z Pump Sprayer, 48-Ounce
The foul-smelling spray that deer cannot stand, made from all-natural and recycled ingredients.
If your arborvitae are in a high-pressure deer zone and you want the most powerful olfactory deterrent, this 48-ounce ready-to-use spray is the one. Its smell is described as rancid — like rotten eggs, old cat food, or rumored wolf urine — but that is precisely why it works so well. The manufacturer claims it will not wash off during rain, irrigation, or normal watering, and it is made entirely from natural and recycled ingredients with no petro-chemicals. Reviewers confirm it is extremely effective against deer, rabbits, and squirrels, protecting hostas and young tree branches.
The trade-off is the sprayer. Buyers consistently report that the included E-Z Pump sprayer clogs frequently because the thick formula does not spray evenly. You may need to transfer the liquid to a better spray bottle with a wider nozzle for reliable application. The scent profile is also much stronger than the minty Deer Out or the spicy I Must Garden, so you will want gloves, goggles, and no wind when you spray.
At 14.2 x 5.5 x 5 inches in dimension, the bottle is tall and wide compared to the smaller I Must Garden concentrate which is just 2.7 x 4.45 x 8.9 inches.
Serious deterrent power
- Extremely effective odor deters even high-pressure deer.
- Claims to not wash off in rain, irrigation, or watering.
- Made from all-natural and recycled ingredients, safe for kids and pets.
Honest drawbacks
- Sprayer clogs easily; may need a replacement bottle.
- Extremely strong, unpleasant odor that lingers during application.
- Requires careful application with gloves and goggles.
Reach for this if: You have a serious deer problem and are willing to tolerate a strong smell and sprayer quirks for the most effective natural deterrent.
Look elsewhere if: You have a sensitive nose or want a more pleasant application experience — the Deer Out is much nicer to use.
5. Deer Stopper II, Liquid Animal Stopper Repellent, 1 Gallon Trigger
The affordable cinnamon-clove spray that smells like the holidays and works for light deer pressure.
For the budget-conscious gardener with a few young arborvitae, Deer Stopper II offers a full gallon of ready-to-use liquid with a pleasant cinnamon and clove scent — a nice change from the rotten-egg repellents. It uses plant extracts instead of harsh chemicals and is safe to use around kids, pets, and vegetable gardens. The scent profile is a deliberate alternative to the original Deer Stopper’s mint and rosemary, and the brand recommends rotating between the two to prevent deer from getting used to the smell.
The honest trade-off is that it requires frequent reapplication. The manufacturer guarantees 30 days effectiveness regardless of rain, though some shoppers prefer to reapply more frequently. Compared to the I Must Garden concentrate which survives a couple of rains, Deer Stopper II needs more vigilance. It is a gallon trigger sprayer, which is easier to use than the heavy, clog-prone Bobbex sprayer but may still feel heavy after covering a tall hedge.
Reviewers report it works well on pumpkins, shrubs, and flowers but is less effective on hostas if not reapplied diligently. For a single arborvitae tree that is getting nibbled, this is a fine entry-level option.
The upsides
- Pleasant holiday-like cinnamon and clove scent.
- All-natural plant extracts; safe around kids and pets.
- Full gallon ready-to-use at a budget-friendly price.
Where it falls short
- Needs reapplication every 10 days or after every rain — high maintenance.
- Scent fades quickly, reducing its deterrent effect.
- Less effective on high-pressure deer or favorite plants like hostas.
A good starting point: Homeowners with minimal deer pressure who want an affordable, pleasant-smelling spray for a small arborvitae or two.
Not enough for: Heavy deer populations or tall hedges where reapplication every 10 days is impractical.
6. EPIC REPELLENTS Deer Scram All Natural Granular Repellent, 2.5 lb Shaker
The shake-and-go granular that biodegrades into nitrogen for smaller, shorter arborvitae.
If you want a no-spray, no-mix option for a few low arborvitae shrubs, this 2.5-pound granular shaker is the simplest tool in the lineup. You just shake it around the base of the plant, and it repels deer through scent before they nibble. It has no unpleasant odor to humans and biodegrades into high-nitrogen organic nutrients, feeding the soil after it has done its job. The granular form means no sprayer maintenance, no worrying about the formula clogging, and no sticky residue on the foliage.
The major limitation for arborvitae is that granulars work best on ground-level plants. For tall arborvitae, the scent barrier may not reach the top growth where deer prefer to browse. Buyers report you must apply it frequently and after a heavy rain, so it is more of a maintenance routine. One reviewer noted the product arrived as a near-dust that was difficult to apply, though it remained effective on artificial turf even after snow melt.
At 2.5 pounds, it is significantly lighter than the 10-pound Plantskydd jug, making it much easier to handle and store.
Simple & clean
- No mixing, spraying, or cleanup needed — just shake and go.
- Unscented to humans; pleasant to apply.
- Biodegrades into nitrogen-rich organic nutrients for the soil.
Its limits
- Granules only protect from the ground up; tall arborvitae tops may remain exposed.
- Needs reapplication after heavy rain — frequent effort.
- Some shipments arrive as dust rather than distinct granules.
Best for: Small, young arborvitae under 3 feet tall, or as a supplemental soil barrier around the base of larger shrubs.
Skip it for: Mature arborvitae hedges over 6 feet tall — a liquid spray that reaches the top foliage is necessary.
Understanding the Specs
Rainfast vs. Water-Resistant
“Rainfast” means the repellent has chemically bonded to the leaf surface after drying (typically 24 hours) and will not wash off in rain. “Water-resistant” or “survives average rainfall” means the product holds up through light rain but will need reapplication after a heavy downpour. For arborvitae, which have waxy needles that repel water, a rainfast sticker is the more reliable option.
Concentrate vs. Ready-to-Use (RTU)
Concentrates (like I Must Garden and Deer Out) require you to mix the liquid with water in a separate sprayer before application. They are more cost-effective per square foot and let you customize the strength. RTU products (like Bobbex and Deer Stopper II) are already diluted and come in a spray bottle or trigger — they are more convenient for quick spot-treating one or two plants but more expensive per application.
