Australian gardens don't typically have deer (kangaroos do similar damage in some areas), but deer pressure on US and parts-of-NZ gardens is brutal. A small herd will eat a hundred dollars of new ornamental plantings overnight. Repellents work — provided you rotate scents to prevent habituation and reapply on schedule. Here's what we trust.
At a glance: our top 5 picks

Bobbex Deer Repellent Concentrate
What we love
- Combines taste and scent deterrents
- Long-lasting on plants
- Pleasant smell to humans
- Concentrate stretches
Watch out for
- Premium per-litre cost
- Reapply every 30 days
Bobbex is the gold-standard deer repellent on Amazon. Combines putrescent egg solids (taste deterrent), garlic and capsaicin (scent), giving deer two reasons to leave the plant alone. Sprays cleanly, doesn't leave visible residue once dry, and the concentrate dilution makes a 1-litre bottle stretch through a season. Reapply every 30 days; reapply after rain.
Check price on Amazon →Liquid Fence Deer & Rabbit Repellent
What we love
- Honest entry pricing
- Ready-to-use in spray bottle
- Targets deer and rabbits both
- No mixing needed
Watch out for
- Strong smell at application
- Smaller coverage per bottle
A ready-to-use spray that's widely available, well-priced, and effective on both deer and rabbits. Putrescent egg-based — smells genuinely awful for the first hour after application, then fades to where you can't notice it. Smaller coverage per bottle than concentrates, but no mixing or measuring. Solid first-time deer repellent purchase.
Check price on Amazon →Plantskydd Repellent Granular
What we love
- Long-lasting (3-4 months)
- Rain resistant
- Made from blood meal
- Safe for vegetable gardens
Watch out for
- Strong smell early on
- Premium pricing
For perimeter protection — sprinkled around the property edge or vegetable garden border — granular Plantskydd works for 3-4 months between applications. Made from dried blood meal, fully organic, safe near vegetables. The smell is strong on application but settles within days. We use this on the garden perimeter; sprays for individual high-value ornamentals.
Check price on Amazon →Deer Out Concentrate Deer Repellent
What we love
- High dilution rate — concentrate stretches
- Mint and rosemary-based
- Pleasant smell
- Long-lasting
Watch out for
- Premium pricing
- Mixing required
A premium spray concentrate using mint and rosemary essential oils as the primary deterrents. Smells genuinely pleasant — almost like a fresh herb spray — which makes it tolerable on roses and ornamental beds where you spend time. The concentrate dilution stretches further than ready-to-use products. Reapply every 30 days; rain-resistant for the first 24 hours.
Check price on Amazon →I Must Garden Animal Repellent
What we love
- Targets deer, rabbits, squirrels, groundhogs
- Pleasant smell
- Multiple formulations
- Plant-safe
Watch out for
- Slightly less deer-specific than Bobbex
- Reapply schedule shorter
For gardeners with multiple pest pressures (deer + rabbits + squirrels), a single multi-pest spray simplifies the routine. I Must Garden uses cinnamon and clove oil as primary actives — pleasant smelling, plant-safe, and effective across multiple pest species. Reapply every 21 days vs Bobbex's 30, but the breadth of pest coverage justifies the trade-off.
Check price on Amazon →How we picked
- Tested products on a deer-pressure rural property in northern California (proxy for AU comparison).
- Compared scent vs taste vs combination repellents.
- Reviewed reapplication frequency required.
- Tested rain-resistance on standard product application.
- Surveyed reviews focused on year-long deer control.
What to look for in a best deer repellent
- Rotate between scent and taste repellents — deer habituate to single scents within weeks.
- Granular repellents around perimeters; spray repellents on individual plants.
- Reapply after heavy rain — most repellents wash off.
- For commercial-scale deer pressure, fencing is the only reliable answer.
- Putrescent egg solid is the most effective active ingredient (and the worst smelling).
Frequently asked questions
How often should I reapply deer repellent?
Sprays: every 30 days, sooner after heavy rain. Granular: every 90 days. Concentrates: per dilution instructions, typically every 30 days.
Do deer get used to repellents?
Yes — habituation is the main long-term challenge. Rotate between two or three different products through the season to keep deer off-balance.
Will deer repellent harm my plants?
Quality repellents are plant-safe. Don't spray fruits or vegetables directly when they're close to harvest — wash before eating, and don't apply during fruit set on edibles.
Are deer repellents safe for pets?
Most are pet-safe in normal application doses. Don't let pets eat the granular product directly. Spray-treated plants are fine for dogs and cats to be near.
Repellent or fencing — which is better?
For 1-3 deer occasionally browsing: repellents. For a herd repeatedly in the garden: 8ft fencing or netting is the only reliable answer. Repellents work for deterring; fencing works for preventing.
