How To Keep Birds Out Of Greenhouse?

Although birds play a good role in keeping pests away from your plants, you’ve to repel them to protect your plantation. While at it, remember these feathered friends are an essential part of the ecosystem. As such, you have to think of safe ways to keep them away without harming them. Below are techniques you can employ to keep birds away from your greenhouse.

1. Using Bird Nets

Installing bird netting is one of the most effective ways of keeping birds off your greenhouse. The best thing about the net is its effectiveness and safety. It’s a highly reliable method, especially because it’s purely natural and also resistant to water and extreme heat. This is how you anchor bird nets in your greenhouse:

  1. Get a net with holes less than a centimeter
  2. Unroll it and cut it into sections fitting your greenhouse’ sides
  3. Install anchors like a plastic strapping where you will attach the netting
  4. Fix nets on both sides to cover all the ventilations

Using a net ring and a C ring tool will prove easier in the mounting process. Also, ensure you confirm the net holes will not allow even the small birds. Such holes only allow insects, which you may need for cross-pollination.

2. Use Repellents

Repellents are not always ideal although you can always find nontoxic options. They may come in the form of gels, sprays, or simply a repellent diffuser. Also, it’s not advisable to use store-bought bird repellent near food crops. 

To be on the safer side, you can prepare natural bird repellents at home. Crush dry chili pepper and mix it with water and apple cider vinegar. If it’s sunny, you only need to pour your blend into a clear jar and place it in the sunlight to diffuse naturally. If not, then heat the solution and place it near your greenhouse. 

3. Use Deterrents

The terror eye balloon is probably the most widespread bird deterrent known. You can always find it in most stores stocking garden accessories. When you fix them near your greenhouse, they scare birds by producing awkward sounds. Besides, their ‘eyes’ resemble those of a predator so most birds will not come anywhere close.

Scarecrows are also very common bird deterrents. However, you have to be creative when making them because the birds are not foolish either. Your scarecrow should be flexible and move a bit. You may also need to change its outfit occasionally as well as relocate it to keep the birds on guard. 

How about using wind chimes to deter birds from accessing your greenhouse? It’s a brilliant idea because it also serves as a décor item. Birds don’t love the loud, sudden noises. Unfortunately, with time they may get used to it, so this cannot be a long-term solution to your problem.  

Are These Methods Safe For Birds?

Certainly. All the above methods are purely natural, and therefore safe for all birds. For the commercial bird repellents, always ensure they are nontoxic before purchasing. Anything containing 4-Aminopyridine or written ‘Avitrol’ is highly toxic and will kill birds rather than repel or deter them. 

All the other methods are safe. You only need to up your creativity game to avoid monotony unless you opt for the netting. For repellents and deterrents, you may need to come up with additional ideas like hanging CDs. Their reflective nature scares away the birds.

Does Aluminum Foil Keep Birds Away?

Birds find aluminum foil very irritating to their beaks. Also, just like CDs, aluminum foil is shiny and the reflection doesn’t sit well with their eyes. For it to work effectively, you need to cut relatively large foil pieces and hang them outside your greenhouse.

Ensure you place these foils somewhere close to the vents. Even if they know there is an opening, they cannot peck the foil or enjoy looking at it. The results are even better during sunny seasons because of greater reflection.

Can Erecting a Bird Feeder Deviate Their Attention Away From the Greenhouse?

 If you attract many birds, you can erect a bird feeder for them. So, will a bird feeder deviate its attention from the greenhouse? The answer is no. This will not necessarily keep your greenhouse safe.

First, you cannot satisfactorily feed all the wild birds at the same time. Again, birds are curious and exploratory. They may feed and then visit the greenhouse to further devour the berries they see in that greenhouse.

If you intend to feed the wild birds, do it out of goodwill but still invest in effective ways to keep them from your greenhouse. Since you will not be targeting specific bird species, you must consider several factors. Among the most important things to consider are the birds’ safety, feeding space, type of feed, and the environment.
