Best Deer Repellent Spray for Shrubs: 3 Options Compared
As an Amazon Associate we earn from qualifying purchases.
Deer can strip the new growth from shrubs in a single night, and a spray repellent is one of the most common tools for protecting them. The best deer repellent spray for shrubs is not simply the strongest smell on the shelf. It is the product that matches your shrubs, your weather and the time you can spend reapplying it. This guide compares three deer and rabbit repellent sprays using the supplied listing titles and bullet points, together with two university extension publications on deer damage and repellents.
Quick answer
- The Liquid Fence ready-to-use spray comes as a 2-pack of 1-gallon bottles, with no mixing needed, and its listing says it is rain resistant and labeled for shrubs and trees.
- The Bobbex concentrate in a 32 oz bottle must be diluted before use. Its listing describes a long-lasting product, but the extension sources give a shorter reapplication interval.
- The Everguard ready-to-spray 32 oz bottle is described as egg-based with thyme, cinnamon, clove and garlic oils. Both sources say egg-based repellents are among the more effective types.
- All three are repellents rather than barriers. The sources say repellents only reduce browsing and must be reapplied, so no spray should be the only protection for a valuable shrub.
How we chose
We started with three products supplied for this guide, and all three have titles and bullets that describe a deer repellent spray labeled for shrubs, trees or ornamental plantings. Each one stays in the comparison. We did not use price, star rating, review count or stock status for any choice, and we did not add any specification that is not in the product file or in the sources.
The sources were used to judge the claims in the listings, not to rank the products. The Montana State publication covers how repellents work and how well they perform, and the Utah State publication covers the timing and conditions for applying them. Where a listing makes a claim about duration or effectiveness, this guide compares that claim with what the sources say.
The three repellent sprays compared
Liquid Fence Deer and Rabbit Repellent, ready-to-use spray, 1 gallon, 2-pack
The Liquid Fence Deer and Rabbit Repellent Ready-To-Use Spray, 1 Gallon, 2 Pack is sold as a ready-to-use liquid with no dilution. The bullets say deer and rabbits avoid treated plants because of a scent aversion, rather than because they have eaten the plant. They say the spray is for ornamental gardens, flowers, shrubs, trees and vines, and that it is rain resistant and starts to work immediately. The listing says it will not harm plants and animals when used and stored as directed. It also says to shake well before each use and describes the product as applied year-round.
The year-round wording conflicts with one of the sources. The Utah State publication says repellents must be applied in above-freezing temperatures, so the listing’s year-round statement does not match that limit. This guide does not pick a side on the conflict. Check the label for the temperature range before you spray in cold weather.
Bobbex Concentrated Deer Repellent, 32 oz
The Bobbex Concentrated Deer Repellent, 32 oz. is a concentrate that must be diluted in water before use. The bullets say it can be used in an E-Z pump device once mixed, and they say it is intended for direct application to the foliage of ornamentals and most edible vegetables. The listing says it is not designed for most edible leaves and herbs, or for rough-skinned berries such as strawberries and raspberries. It describes a wintergreen scent that repels by taste and odor, and it says the 32 oz concentrate lasts up to two months after application.
The listing also says the spray will not wash away once applied and calls it proven to be the most effective long-lasting spray on the market. Neither claim is supported by the sources in this guide. The Montana State publication says repellents work for one to two weeks and need reapplication after rain, and the Utah State publication says to reapply every four to five weeks or after precipitation. The listing’s two-month figure and its no-wash claim therefore do not match either source. This guide does not choose between them, and readers should follow the label and the extension guidance.
Everguard ADPR032 ready-to-spray deer and rabbit repellent, 32 oz
The Everguard ADPR032 Ready to Spray Deer and Rabbit Repellent, 32 oz is a ready-to-spray liquid in a trigger bottle, with no mixing. The bullets say it is made with putrescent whole egg solids and with thyme, cinnamon, clove and garlic oils. They say the treated area becomes unpleasant to deer and rabbits, and that the formula has no rotten odor once applied. The listing says it holds up to rain, snow and watering and is labeled for vegetable gardens, flower beds, lawns, ornamental shrubs and trees. It also says to read and follow the label.
The egg-based formula matches what the Utah State publication describes. It says the most effective repellents contain eggs, preferably putrid eggs, and that deer will often avoid plants sprayed with putrescent egg solids for up to six weeks. The listing does not give a duration, so the six-week figure is from the source and not from the listing. The listing’s rain and snow claim is not covered by the sources, and the reapplication guidance in the sources still applies.
Using a deer repellent on shrubs
The sources set clear limits on what a spray can do. The Montana State publication says that typically repellents will only reduce damage, and that even the most effective repellents reduced deer browsing by about 60 percent in the studies it cites. It also says repellents work for only one to two weeks, so reapplication is needed to protect new growth. Shrubs in spring are growing quickly, which means new leaves appear between sprays and need coverage.
The Montana State publication also says repellents are effective only if deer have other food available to them, and that a deer that is hungry enough may still browse treated plants. A spray is more likely to help when other food sources are present, and less likely to help in a hard winter with little forage. The guide does not have data on that question for these specific products.
Timing matters. The Utah State publication says to apply repellents only in above-freezing temperatures and to reapply every four to five weeks or after precipitation. That schedule is a source guideline for repellents in general, and it is more conservative than the listings for some of these products. Keep a note of when you sprayed and when rain fell, so you know when the next application is due.
Cost is a practical consideration. The Utah State publication says the cost of repellents may be prohibitive if the area to protect is large. The ready-to-use sprays and the Bobbex concentrate are sold in different sizes and forms, so the amount of product needed for your shrubs and the number of reapplications will decide the total cost. The listings in this guide do not give prices, so work out the cost yourself from the label and the size you buy.
A repellent is also not a barrier. A deer can still reach treated shrubs if the spray wears off, and young shrubs can be damaged quickly. For a valuable plant, pair the spray with physical protection, such as fencing or netting, where the local situation allows. The sources do not describe a specific fence height, so check local extension advice for that.
Shrubs that have already been browsed may recover, but the sources do not say how quickly. For general background on how plants respond to damage, see do trees heal from wounds, which covers how trees seal and recover from injury, and how xylem moves water, which explains how a damaged stem carries water to new growth.
What we could not verify
This guide relies on listing text and two extension publications. It does not include any trial of these sprays on deer, and it cannot say which product deters deer best on a given shrub. The claims about duration, rain resistance, safety and effectiveness that appear in the listings come from the sellers and are not confirmed here.
What the sources do not say
Neither source names a specific product, so neither can say which spray is best. The sources do not test the three products in this guide. The Montana State publication gives a reapplication interval of one to two weeks for repellents in general, and the Utah State publication gives four to five weeks. The sources do not say which of those intervals fits a specific product, and the guide does not pick one.
The sources do not address the rabbit claims in the three listings, so this guide does not confirm rabbit control. The sources also do not address whether the sprays are harmless to pets, birds or aquatic life, so those listing claims are unverified. The Bobbex and Everguard listings describe uses on edible crops, and the sources do not address that use, so the guide does not make a claim about edible plants.
The listing claims that a product is the most effective or that it will not wash away are not supported by either source. The guide reports those claims as the listing’s own statements.
Frequently asked questions
Do deer repellent sprays stop deer completely?
No. The Montana State publication says repellents typically only reduce damage, and that even the most effective ones reduced browsing by about 60 percent in the cited work.
How often should I reapply a repellent?
The Montana State publication says one to two weeks, and the Utah State publication says every four to five weeks or after rain. Follow the label for the product you buy and check after rain or new growth.
Can I spray when it is cold?
The Utah State publication says to apply repellents only in above-freezing temperatures. The Liquid Fence listing says it is for year-round use, which does not match that source, so check the label before spraying in cold weather.
Is an egg-based spray better?
The Utah State publication says the most effective repellents contain eggs, preferably putrid eggs. The Everguard listing describes an egg-based formula, but the sources do not rank the Everguard above the others.
Will a spray protect shrubs in a hard winter?
The sources say repellents work only when deer have other food available. In a hard winter with little forage, a spray may be less reliable, and physical protection may be needed.
