Efficacy tests of Bird Free repellent gel were initiated in 2017 and are still on-going. As of June 2021, our researchers reported 100% efficacy over four years. Case studies indicate even greater longevity, with many clients confirming that installations carried out in 2014 and 2015 remain effective as of June 2022.
The European Union, having examined our latest efficacy data has authorised us to state on the label that Bird Free will remain effective for a minimum period of four years. We have submitted the same data to the UK’s Health & Safety Executive and, as of June 2022, continue to await a response.
We are now confident in stating that Bird Free will remain effective for a minimum of five years, provided it is installed in accordance with the manufacturer’s specifications.
Unlike some traditional bird control methods, our fire gel requires no maintenance or replacement and, as the Bird Free gel is impervious to all weather conditions, you can install the dishes and leave them to do their work for the next five years or more. By contrast, bird control solutions such as pigeon netting can become damaged, collect debris or even get dead birds caught in them. Efficacy will drop drastically in such circumstances and access will be required to rectify the situation. With Bird Free on the other hand, you don’t need to worry about anything like this happening. Rain, snow, wind, extreme heat, etc will have no negative effects on the optical gel. Bird Free even remains effective when covered in dust or dirt.
Because it is injected into the dish at very high pressure (up to 60 BAR) optical gel is stable. It will not melt or run regardless of how high the temperature gets. It will continue to do its job in all conditions for an extended period of time.
We wanted to check that pollution would not cause the efficacy of our bird control gel to drop. After several trials we found that the fire gel will remain completely effective even when polluted by different substances in the environment. Even if it darkens in appearance over time it will remain completely effective at deterring birds.
One thing that can happen with anything left unattended for long periods is contamination with dust or dirt and we have seen this same with Bird Free in certain circumstances. The good news is that particles will not block UV light and the bird control gel will continue to repel birds by changing their behaviour should they at any point try to return. You can be confident that no matter how much dust or dirt accumulates Bird Free will remain effective.
If your property is in an area where pigeons or other birds are present, it is a good idea to make some preparations. The first thing we recommend is a risk assessment to determine whether bird control is required.
There are several factors that you may want to take into consideration while making this assessment. Remember your goal should be to find out the possible losses and damage that a bird infestation could cause; then you can compare the results with the costs of carrying out the bird proofing. In many cases the value of bird proofing will soon become apparent.
If you do not have the knowledge or the skills to perform this assessment, you should consult a bird control professional. Either way, this step is essential if you’re not sure it's worth your time, effort, and money to take bird control measures.
First, an assessment needs to determine the potential severity of an infestation . How many pigeons are currently present? Given that pigeons born on site will themselves nest and breed there, how quickly is the pigeon population likely to grow? Is there a source of food or water for birds in the area?
All these questions must be answered. They will give you an idea of the risk and the potential severity of the problem. You will then understand whether you need to take measures to avoid or eliminate an infestation.
From here you can assess the possible damages and losses that could be caused by an infestation. There are two main types of bird problems that you need to consider. First is the material damage; How much destruction could an infestation cause to the site? How much would it cost you to regularly clean up after the birds?
The second and equally important bird proofing problem that you need to take into consideration is the possible health and safety risk. Birds such as pigeons carry diseases that can be transmitted to humans, and you don't want to risk someone getting sick because of the infestation. Nor should safety be compromised by risk of slipping.
After you've fully assessed the situation, you will have a clearer idea of the long-term value of carrying out bird control work. Once you tally up the possible costs you will incur after all the potential damage done by a bird infestation, you can compare the results with the costs of the bird control treatment itself.
To give you an idea of all the possible damages caused by a pigeon control problem, we have listed below the most important problems that can be avoided by using Bird Free gel to control pigeons.
As mentioned above, pigeons and other birds can transmit diseases to humans. In most cases, this process happens through bird droppings. If you have a bird infestation problem, you should install a bird proofing method as soon as possible.
Air conditioning units and water sources can easily become contaminated by avian pathogens. Pigeon droppings can contaminate these systems and propagate disease very quickly. These problems can take some time to solve once they occur so the prevention of such situations should be of the utmost priority.
A bird infestation can cause problems you may not expect. In many cases, a bird infestation is a packet deal and with it you will encounter insect problems as well. Birds can often be infested with different types of insects. The most common ones are biting insects, bird mites, and flies. All of which could become a problem for humans as well.
Bird droppings are highly acidic and can cause significant to harm solar panels, the paintwork of a car, and even cause corrosion of buildings and other structures. Putting aside health and safety risks or aesthetic concerns, an untreated pigeon infestation can prove extremely costly in the long term if not treated with a deterrent in a timely manner.
The cooing of nesting pigeons can be a huge annoyance at home or in the workplace and that’s exactly why you will need a reliable bird proofing service that will deal with a bird infestation. You may not be able to focus on your work or running your business because of the constant noise. In a residential setting, the quality of your sleep will also be affected.
Many roosting sites are in non-sheltered public spaces where bird droppings can become wet. There are several dangers associated with this, the most important one being the massive growth of the pathogens in the pigeon droppings and the increased risk of diseases spreading.
If pigeons continue nesting under solar panels the photovoltaic panels can become coated with droppings, which may over time cause them to stop working entirely. Consult a bird control professional if you have pigeons nesting under solar panels.
Businesses that encounter a bird infestation can expect damages and losses caused by noise and foul odours. In many cases, the relationship between a business and its customers can be negatively affected by a bird infestation.
Fines can be imposed due to non-compliance with health & safety legislation such as the Food Safety Act 1990. The costs of non-compliance with health & safety legislation can be considerable and will damage a business’s reputation, especially in sectors such as hospitality.
Karstadt Building, Hamburg
Built in the 1950s, the former Karstadt department store in Eppendorf is a listed building that battled with a pigeon infestation for many years. The problem became so severe that businesses couldn’t open their windows because of the smell. After being cleaned and treated with the optical gel in 2014, the problem disappeared. Eight years later there is still no sign of pigeons.
Bristol Temple Meads station
The exterior of Bristol Temple Meads station is covered by a 150-metre glass canopy which acted as a perfect shelter for pigeons. Constant cleaning was required below the canopy and cleaning costs continued to escalate. In 2014, Bird Free was installed and the bird infestation problem was finally solved. Eight years later the canopy remains clear of pigeons.
Chiesa della Spina, Pisa
One of the oldest buildings in Pisa, the Chiesa della Spina dates from the 13th century. Pigeons had been nesting behind the medieval statues of the church for years and the City of Pisa had been unable to eradicate the infestation. After the church was renovated in 2015, Bird Free fire gel was applied to the statues. The pigeons have not returned since.
Palazzo Venezia, Rome
The Palazzo was a papal residence in the 15th century. Today it is a tourist attraction, but many visitors complained about fouling on the floor below the rafters of the loggia where pigeons used to roost. In 2015, Italy’s Ministry of Heritage, Cultural Activities and Tourism decided to install Bird Free gel on the rafters to prevent the pigeons from roosting. All the pigeons promptly abandoned their night roosts. As of June 2022, there are no pigeons or pigeon droppings to be seen.
Quiron Dexeus Hospital, Barcelona
The interior of the light wells above the main concourse of this Spanish hospital were a perfect place for pigeons to nest. Spikes were installed inside the light wells but the pigeons simply nested on top of the spikes. Prior to the spikes being replaced with Bird Free in 2018 the floor below the light wells had to be constantly cleaned throughout the day. Since Bird Free was installed the pigeons have not returned.
To learn more about these projects please see our case studies page. There you will find full details of these installations. We also have several examples of successful installations of Bird Free on our YouTube channel.
