How it works

Bird Free is formulated to stimulate three senses of the bird: sight, smell and touch. These three stimuli combine to create avoidance learning in birds.

Sight

Bird Free’s proprietary gel mixture contains pyranine, the same colouring agent used in highlighters. This fluoresces when excited by UV radiation, causing the gel to glow with ultraviolet light. Invisible to humans, the UV light creates an impression on the bird similar to shimmering fire (hence the name Fire Gel™), causing it to avoid landing on surfaces treated with Bird Free. This avoidance reaction is observed immediately after Bird Free is applied.

Smell

Bird Free contains peppermint oil, long known as an effective bird repellent. Studies have shown that the menthol contained in peppermint derivatives acts as a primary repellent in birds due to its action on olfactory and trigeminal nerve endings located in the bird’s nose, mouth and eyes. (The trigeminal nerve is closely related to the olfactory nerve. It conveys facial sensations to the central nervous system.) The odour quality and pungency of the menthol is sensed by the olfactory and trigeminal systems of the bird, respectively, and creates an aversion response.

Synergy between visual and olfactory stimuli

In effect, these two stimuli, visual and olfactory, act together in synergy, warning the bird not to approach. As a result, birds quickly learn to keep away from surfaces treated with Bird Free.

In the video showing the avoidance reaction, pigeons that used to sit on the chimney every morning learnt after the first day not to go near it. A video of the same chimney taken on 11 October 2016, three years after Bird Free was applied, shows many pigeons flying over the chimney, but none land on it.

Touch

While the vast majority of birds are deterred by Bird Free's visual and olfactory stimuli and will not come into contact with the gel, where nests have been removed and treated with Bird Free a nesting bird will often be seen attempting to return to the nesting site immediately after Bird Free has been applied, causing it to touch the gel, which is very sticky. Due to the gel’s high viscosity the bird will not be harmed. However, birds abhor anything sticky on their feathers, so the bird only needs to touch the gel once and it will never return.

 

Example

Pigeons had been nesting on a junction box inside this underground car park for many years, resulting in damage to cars parked below. The nest was removed, and the surface of the box was disinfected. Dishes of Bird Free were then fixed where the nest had been at 15cm centres. Dishes were also fixed around the edge of the box at 25cm centres. The pest controller who carried out the treatment inspected the box three days later, and reported:

“There had been a pair of pigeons nesting against the wall for an extended period of time prior to clean-up and installation of Bird Free. After hree days the top of the junction box was inspected. It was clear that there had been an attempt to reoccupy the habitat. There was a footprint in the Bird Free and a trail of gel was visible across the top of the box. There was evidently only a single attempt. Now there is no sign of pigeons in the vicinity of the junction box.”

 

How Bird Free effects the senses of the bird

Bird Free is a pigeon repellent formulated to stimulate three senses of the bird: sight, smell, and touch. These three stimuli of the bird repeller combine to create avoidance learning in birds. It is a wonderful method that prevents any harm being done to birds whilst also solving the pigeon problems they may cause. You no longer need to use aggressive and obtrusive pigeon repellents to stop pigeons from infesting your property or place of business. 

Sight 

Bird Free’s proprietary gel mixture contains pyranine, the same colouring agent used in highlighters. This fluoresces when excited by UV rays, causes the pigeon repellent gel to emit ultraviolet light. This type of light is invisible to human eyes but the birds can see it and they do so in a very particular manner.  

For birds, the UV light creates an impression similar to shimmering flame. That's also where the name Fire Gel came from, first coined by the British press. Like most animals, a bird will avoid what is perceived as fire so it will not land on surfaces treated with Bird Free repellent. This avoidance reaction can be observed immediately after Bird Free is applied. 

Smell 

Bird Free also contains peppermint oil, long known as one of the most effective pigeon repellents. Studies have shown that the menthol contained in peppermint derivatives acts as a primary repellent in birds due to its action on olfactory and trigeminal nerve endings located in the bird’s nose, mouth, and eyes. (The trigeminal nerve is closely related to the olfactory nerve. It conveys facial sensations to the central nervous system.)  

It was clearly observed that birds have a drastic adverse response to this substance. It can be similar to how many other animals react to bad smells. They try to avoid it as much as possible. The odour quality and pungency of the menthol are quite high. So, when it is sensed by the olfactory and trigeminal systems of the bird, it creates an immediate aversion response that is perfect for pigeon proofing purposes. 

The Synergy Between Visual and Olfactory Stimuli 

In effect, these two stimuli, visual and olfactory, act together in synergy, warning the bird about a clearly perceived danger. Keep in mind that both fire and bad smells are factors that help birds and other animals to perceive potential danger and avoid it. As a result, birds quickly learn to keep away from surfaces treated with Bird Free repellent. 

In the video showing the avoidance reaction, pigeons that used to sit on the chimney every morning learned less than a day after the pigeon repellents were installed, not to go near it. It became a dangerous place for them extremely fast. A video of the same chimney taken on 11 October 2016, three years after Bird Free was applied, shows many pigeons flying over the chimney, but none landed on it. Proving the long-term efficacy of the method, far more than traditional pigeon repellents. 

Touch 

While the vast majority of birds are deterred by Bird Free's visual and olfactory stimuli and will not come into contact with the gel, where nests have been removed and treated with Bird Free repellents, a nesting bird will often be seen attempting to return to the nesting site immediately after Bird Free has been applied, causing it to touch the gel, which is very sticky.  

Due to the optical gel’s high viscosity, the bird will not be harmed. However, birds abhor anything sticky on their feathers. They instinctively understand that their ability to fly can be negatively affected by this type of substance. So, the bird only needs to touch the gel once, and it will never return. Making the sticky gel a very effective method for pigeon control.

10 Advantages to Use Bird Free Pigeon Repellents

  1. Makes Birds Avoid the Treated Site  

What makes this bird repeller one of the best pigeon repellent alternatives is the ability to make a site inaccessible without physically harming any bird in the process. A treated site will automatically become dangerous in the perception of the birds. So, they will try to avoid it as much as possible.  

As a result, you will no longer need to worry that the site treated with the optical gel will be infested with birds, nor will you encounter any pigeon droppings, in the future. After a short observation, it will become clear that this method is one of the most effective repellents on the market. 

  1. Makes Resident Birds Abandon Long-Standing Habitats

The efficacy of this bird repeller is not limited to the birds that may be looking to infest the site. It also directly affects the ones that are currently infesting your property. In many cases, their habit may still be to return to their current habitats but the perceived dangers created by the pigeon repellents will prevent the birds from doing so. 

They will be forced to leave and look for other places that do not present a danger. As you can see, this gel is not only a prevention method, it can also be used to get rid of your current pigeon problems. Even pigeons that have been using a site for years will completely abandon the site overnight. 

  1. Eliminates the Most Severe Infestations

Another advantage that Bird Free has over other pigeon repellents is its efficacy. Most other methods will produce different results based on the seriousness of the infestation but that is not true of the bird gel. So long as the spacing guidelines are followed, it will have the same effect regardless of the number of pigeons that infest the site.

You won’t encounter pigeon proofing situations in which only a part of the infestation is eliminated while the rest remain. Every single bird will flee the treated area in a day and not a single one will return within two or three days. Even new birds that may be tempted to visit the treated site will be scared away by the dangers perceived by their senses. All of this without harming the birds at all.

  1. Shows Immediate Results

Efficacy matters a lot when you consider the elimination and prevention of any type of infestation but also how long the product takes to become effective is a huge factor. In this case, our pigeon repellent is one of the best options for pigeon proofing. 

As mentioned above, it only takes a day, at most, for even the most severe infestations to be dealt with. Compared with other methods used to cope with pigeon infestations, Bird Free is by far the most efficient option. 

  1. Causes no Harm to Birds 

Let us make this point as clear as possible. The gel will not harm any bird in any way. A site treated with our pigeon repellents will be perceived as extremely dangerous by birds but this is part of the trick. Even if a bird does come into contact with Bird Free, it will not be harmed. 

Some birds will ignore the perceived fire caused by the gel, especially when dealing with a highly infested area but when they do come into contact, the bad smell and sticky substance will cause them to perceive an even higher amount of danger. This will force their instincts to flash continuously until they leave the treated site. This is why Bird Free is the perfect pigeon proofing method that doesn’t cause any harm.

  1. Made Out of Safe Ingredients 

All the ingredients from which the gel is created are safe so you don’t need to worry about harming any birds but that’s not all you should consider while choosing a pigeon control method. 

Besides the safety of the birds, you should also consider the safety of your family and pets. In most cases the repellents will not affect their sight or sense of smell in any way either. However, direct contact with the gel should be avoided. It can cause skin or eye irritation and ingestion can be dangerous. So, you should not allow your pets or kids near a treated area. 

  1. Doesn’t Affect the Pets  

You may also wonder if the gel affects the senses of your pet in the same way it does with pigeons and other birds. The answer is no, dogs and cats see the world in a very different way to birds and as such are not deterred by the gel. 

This is why you should make sure the treated site is out of reach of any pets. Thankfully, pigeons also tend to avoid dogs and cats, so it is highly unlikely you will be treating a site that is accessible to your pets. 

  1. Is Proven to Be Effective Over Five Years 

So we’ve discussed how effective and efficient our bird repeller is. What about the efficacy period? Well, after several studies and practical experiments, we can confirm that the gel will remain effective for over 5 years and has been known to work way beyond that in ideal conditions.  

Even taking into account many external factors such as weather, temperature and amount of sunlight, we can be sure the site you will treat will be avoided by any pigeons for at least five years if Bird Free is installed correctly.  

  1. Invisible from Below 

Another advantage that our repellent has is the fact that it is invisible from below. Other pigeon deterrents and pigeon control strategies will create changes in the aesthetic of a treated site and that may be problematic for historical sites or places of business. Even clients from residential areas may want to avoid unnecessary aesthetic damage to their homes. 

Thankfully you won't have to deal with any visible changes that may affect in any way the aesthetics of the treated site when using our repellent. As Bird Free is extremely low profile, it is hard to spot from below so in the majority of cases, this should not be any concern. 

  1. It’s Discreet, So Not Very Visible on Buildings

Although you can’t say our product is completely invisible, it is highly discrete in its design compared to alternatives such as spikes or nets. So, even if you are going to use it on a building, it’s not going to generally affect its aesthetic appeal.  

The changes made are minimal, and you could say that without paying close attention, the treated area may not even be detectable. Of course, if you are intentionally looking for it, you will still be able to find it. You may want to know exactly the places where the gel was applied but even from above, Bird Free gives a neat and uniform finish and doesn’t collect debris or dirt like other pigeon repellent options.
