The Electrostatic System is an active deterrent for pigeons as it directly acts with pulses to which pigeons are sensitive, causing them to feel a disturbance that drives them away without causing any harm. All other methods (which are outdated and certainly surpassed) are passive methods that disturb pigeons only with their static presence, cluttering the architectural elements where pigeons usually perch in one way or another. Therefore, it is natural that their deterrent effect is limited over time because sooner or later, pigeons become accustomed and return, despite the presence of spikes or other obstacles. Moreover, some old methods like spikes (steel or plastic needles) risk causing harm to pigeons (such as punctures or even injuries). It's easy to scare away pigeons; any method, in principle, works.
The real challenge is to ensure that pigeons never come back, and this can only be guaranteed with an active system like the Electrostatic System.

Our system has been on the market for more than 30 years, and we hold the patent for it. We have protected major works of art in Italy and Europe. Italian and foreign Superintendencies approve and appreciate our system. Animal rights activists accept our system because it causes no harm to pigeons. We provide guarantees for keeping pigeons away from protected works, as pigeons do not become accustomed to the electrostatic impulses.

All the components of the system have been studied and selected to provide all the guarantees of resistance in its structure. The active electrostatic lines consist of rods in stainless steel AISI 316L, resistant to acidic and salty environments; anti-polymerization polycarbonate isolators, which function as both insulators and supports for the steel lines; triple-insulated interconnection cables with a test voltage of peaks at 15,000 volts; impulse generator excited at 230V 50Hz with grounding (or with any other means, such as batteries or solar cells).
These are clearly the primary components of our system. All these elements are on the exterior of the building and therefore must be designed to remain in perfect condition for a long time, resisting deterioration caused by weather conditions or UV rays from the sun.

Pigeons, with their droppings, soil all architectural elements, degrading their aesthetics; moreover, the guano has a high acidity, making it highly corrosive, and therefore, over time, it irreversibly damages the structures. Additionally, with humidity, the guano deposited on architectural structures eventually transforms into fertile humus on which small plants sprout, and their roots penetrate into cracks and porosity in building supports. As these roots grow, they exert a disruptive action, gradually crumbling stones and bricks.

Pigeons are carriers, directly or indirectly, of about 60 diseases, some of which are contagious or even fatal to humans and domestic animals.
We highlight only some of the main diseases dangerous to humans, as emphasized in the "ABC of the Disinfector" magazine by Graziano Dessi and other specialized medical journals:

• Cryptococcosis:
  It is one of the most dangerous diseases. Usually, the infection starts in the lungs and spreads through the circulatory system to all parts of the body. Infections of the brain and meninges, especially in children, almost always lead to death.
• Ornithosis:
  This disease presents the characteristics of an infectious septicemia and atypical pneumonia. Transmission occurs through the air, breathing in the dust of pigeon droppings. The outcome is fatal for pulmonary forms.
• Histoplasmosis:
  It can present itself as an acute or chronic infection, localized or widespread, of the immune system. Clinically, it can be confused with other diseases, including tuberculosis; most infections regress spontaneously, but fulminating cases are fatal.

In addition to diseases, pigeons also carry parasites such as ticks, fleas, lice, and mites.

Our system has been meticulously designed to be, once installed, practically invisible. It is not possible to eliminate pigeons from monuments and replace them with systems that compromise the aesthetics of the work of art almost like pigeon droppings themselves! Furthermore, we are careful in the methods of fastening: we would never allow ourselves to drill elements of works of art that can represent great value for all humanity. In all delicate cases, fastenings are carried out with special reversible resins, so as not to cause any damage to the works of art.

Our system does not cause any harm to either birds or humans. Our system is based on the capillary distribution of spikes of pure electrostatic voltage without electric current on various architectural elements. For this reason, our system is completely harmless. Moreover, the time interval of our voltage spikes is around 2.5 seconds, so even if a pacemaker wearer were to come into contact with our system, there would be no consequence. As mentioned elsewhere, even Animal Rights activists support our system because it deters pigeons without causing them any harm. We can even say that, as a result, we protect pigeons from humans, who, with no disturbances in the buildings, have no reason to harm them anymore.

Certainly, our system complies with all the requirements of EU regulations.
Furthermore, the system is equipped with a special double-insulated input transformer, with a 1:1 ratio according to standards, serving as an isolation transformer.

Absolutely not! The system is based on the deterrent effect of pulses of pure electrostatic voltage, without electric current, and therefore without consumption.
Each electrostatic pulse is very short-lived (about 80 microseconds): they are like flashes of voltage emitted at a rate of about one pulse every 2.5 seconds.
The pulse generator needs to be excited to emit the pulses. This excitement can be achieved either with the normal mains voltage of 230 V 50 Hz, or with a long-lasting battery (6 months), or with solar cells integrated with the generator itself, or with any other method suitable for causing the said excitement. For this excitement (because it's only excitement and not power supply), there is an extremely low consumption of about 7 Watts (equivalent to a normal night light or votive lamp).

Our system is installed solely and exclusively by our highly specialized personnel. All Ettore Galliani employees undergo training before starting the actual installation work. We would never consider entrusting the installation of our system to third parties or occasional personnel, given the guarantees we provide.
Equally important is the qualification and experience of the personnel involved in the design.

Certainly not. Our system does not interfere with any other electrical and electronic systems. Moreover, the cables of preamplification and amplification systems are always shielded against any interference.

Absolutely not. Our system has the sole function of deterring pigeons.
The circuits are always grounded with their negative pole.
No electrical power is involved. No lightning attraction is possible.

Nothing. Our electrostatic pulse generator continues to function, and the electrostatic voltage pulses disperse in the water or snow without any damage. When it stops raining (and humidity no longer disperses the pulses) or when the snow melts, the system resumes functioning exactly as before.

It is not possible to evaluate the system in this way, at a cost per linear meter or per square meter, because the system is actually an integrated system. Therefore, we can only offer a comprehensive price (including materials, labor, fixed costs, etc.), usually excluding only scaffolding or other means to install the system at height.
Pricing per meter is not feasible because the system is closely tied to the complexity of architectural elements, which vary case by case. Labor costs significantly outweigh material costs, so one can consider how much more expensive, at the same size, it is to protect a Baroque or Gothic building compared to a modern, linear one. Other incalculable costs, except comprehensively, include project costs, site visits, and indivisible equipment like the pulse generator, etc.
Presenting the overall price comprehensively guarantees the client a fixed and unchanging price (with all evaluation risks on our part), as is necessary when a client needs to plan a financing program.
Our offers are never approximate or indicative but are always final and binding. This strict commercial approach, in our opinion, is a significant demonstration of the seriousness of our company.

Pigeons do not become accustomed to the discomfort caused by the electrostatic impulses; their behavior remains the same even after many years. Therefore, we can guarantee that our Electrostatic System, if implemented according to a comprehensive protection plan, keeps pigeons away permanently from the protected areas.
Furthermore, it is worth noting that no maintenance is required (unless the system is damaged by external factors). With no pigeons present, periodic cleaning of the monument or building and the adjacent underlying areas is no longer necessary, providing significant economic, aesthetic, and structural preservation benefits.
