Birds can cause a lot of damage in gardens by eating seeds, pulling up seedlings, pecking at fruits and vegetables, and leaving droppings everywhere. While birds certainly have their place in the ecosystem, most gardeners would prefer to minimize bird damage in their vegetable gardens and fruit orchards. Luckily, there are a number of techniques and products available to deter birds from treating your garden like an all-you-can-eat buffet.
Bird Netting
One of the most effective ways to keep birds away from your garden is to cover it with bird netting. Stretch the netting over the entire garden bed or individual plants and anchor it firmly to the ground. The netted barrier prevents birds from being able to land on the plants or reach the fruits and vegetables from above. Look for UV-treated netting that won’t degrade in sunlight. For larger areas like fruit trees, drape the netting over the entire tree and secure it around the trunk.
Advantages of Bird Netting
- Physical barrier prevents access to plants
- Low maintenance once installed
- Lasts for years if cared for
- Available in various mesh sizes
Disadvantages of Bird Netting
- Can be labor intensive to install
- Not ideal for very large areas
- May trap beneficial insects
- Needs to be checked regularly for holes or gaps
Scare Tape
Scare tape, also known as flash tape or bird scare tape, is a metallic reflective tape that shimmers and makes noise in the breeze. The unpredictable flashing and crinkling sounds startle birds and scare them away. Hang multiple strands of scare tape around your garden about 3-5 feet apart. For best results, use a combination of reflective silver tape and iridescent red tape. The changing colors and movement mimic predators and trigger the birds’ instinct to flee. Rehang tape regularly as birds can become used to it over time.
Advantages of Scare Tape
- Inexpensive deterrent
- Easy to install
- Movement and noise frighten birds
- Can cover large areas
Disadvantages of Scare Tape
- May look unsightly
- Can blow around in wind
- Birds may adapt to it over time
- May degrade and need replacing annually
Scarecrows
Nothing signals a garden quite like a scarecrow keeping watch. These traditional bird deterrents work on the belief that their human-like form will frighten and unnerve garden thieves. Make your own scarecrow or pick one up at any garden store. Position it where it has the best view of your garden and move it around occasionally so it appears alive. Combine your scarecrow with noisy wind chimes for added effect. Clothing with eyespots can also make it more intimidating to birds. Just be sure to use weatherproof materials so your scarecrow doesn’t degrade outside.
Advantages of Scarecrows
- Natural looking deterrent
- Can repel birds without harming them
- Fun garden decoration
- Doesn’t require electricity or batteries
Disadvantages of Scarecrows
- Birds may adapt to recognize it’s not a real person
- Not as effective for larger areas
- May degrade or blow over in wind
- Needs to be moved regularly for best results
Fake Predators
Birds have an innate fear of their natural predators like hawks, owls, snakes, and cats. Take advantage of this instinctive fear by placing fake predators around your garden. Lifelike plastic owls with head-turning action or inflatable snakes that move in the wind are especially effective options. Alternate different predator models and reposition them frequently to reinforce the threat. Avoid overusing fake predators though, as clever birds may catch on over time. For best results, combine them with other deterrents.
Advantages of Fake Predators
- Mimics natural threat birds wish to avoid
- Can be very effective if moved regularly
- Fun novelty to decorate garden with
- Affordable option to try
Disadvantages of Fake Predators
- Impact diminishes over time as birds realize it’s not real
- Limited range of effectiveness
- Can blow away or degrade if left outside
- May disturb beneficial birds as well as pests
Repellent Sprays
Chemical bird repellent sprays create an invisible barrier around plants that deters birds using smell or taste. Repellents containing methyl anthranilate produce a grape-like odor that birds dislike. Garlic-based products rely on the strong garlic smell to overwhelm birds’ sense and appetite. Apply repellent sprays according to label directions, coating leaves, stems, and outer fruit surfaces. Reapply after rain or every 7-14 days during bird activity seasons. Beware that overspraying or improper use of repellents may damage plant tissues.
Advantages of Repellent Sprays
- Creates protective invisible barrier on plants
- Non-toxic options available
- Liquid formulas can coat evenly
- Degrades naturally between applications
Disadvantages of Repellent Sprays
- Effects are temporary and require reapplication
- May not deter all bird species
- Could harm beneficial insects if overapplied
- Some birds may adjust to smells over time
Audible Deterrents
For gardens pestered by stubborn birds that won’t budge, audible deterrents may be the solution. These devices use predatory and distress bird alarm calls to trigger birds to flee and avoid the area. Battery-powered ultrasonic repellers, motion-activated sprinklers, and automated noise machines can surround gardens with an offensive wall of sound. Use strategically to target problem areas and do not overdo it, as birds will adjust to constant noise. Rotate different sounds to delay habituation. Audible deterrent effectiveness depends greatly on garden location and bird species present.
Advantages of Audible Deterrents
- Offensive noise disturbs and drives away birds
- Programmable and automated options available
- Can target specific problem spots
- Sounds and Timers can be varied
Disadvantages of Audible Deterrents
- May disturb neighbors if used improperly
- Birds may adapt to constant sounds over time
- Not as effective for large open spaces
- Require electricity source or batteries
Trapping and Removal
When all other options have been exhausted, trapping and removing problem birds may be the last resort. Live traps baited with food can capture birds for relocation away from the garden. Make sure to check local ordinances first, as it may be illegal to trap some bird species. An additional step is to block bird entry points and close off potential nesting or roosting sites to prevent new birds from entering the garden after removal. Excluding access and habitat in combination with trapping has the most lasting impact.
Advantages of Trapping and Removal
- Permanently eliminates specific pest birds
- Can use traps or nets for capture
- Allows for humane release of non-target species
- Combined with exclusion tactics
Disadvantages of Trapping and Removal
- Labor intensive method
- May not be legal depending on species and location
- New problem birds may enter from elsewhere
- Some birds may avoid traps or nets
Combining Multiple Deterrents
Relying on just one technique may not be enough for stubborn garden raiders. The most effective bird control strategy is to combine multiple deterrents together. Use bird netting or repellent sprays for immediate protection. Add in scare tactics like flashing tape, predator decoys, and noise makers. Move visual deterrents around frequently so birds don’t become comfortable. Having a multilayered defense will keep your fruits and vegetables safe from feathered thieves.
Conclusion
Unwanted birds snacking from your garden can be more than just a nuisance. They can devastate vegetable plantings and decimate fruit crops right before harvest. Protect your hard work from uninvited pecking using humane bird deterrents designed to scare rather than harm. Physical exclusion with netting provides reliable protection. Altering the garden environment using reflective tape, scarecrows, and predator models disrupts birds’ feeding behavior. Repellent sprays and offensive noise can tip the balance further in your favor. Just remember there is no one size fits all solution. Tailor your approach using multiple deterrents and adapting to what works best to outsmart your garden invaders.
