– Pigge. A series of barbed wire, a kind of "fakir", which is attached with glue or silicone to e.g. cornice. They make the animals insecure (this is also the intention), but can also harm them on landing. Least evil. Juveniles in particular can be harmed by these fakirs as their wings can get caught in the stinging metal spikes and young birds do not have the strength to get free.

– Cornices and other ledges are then made inclined (more than 45 °), that the pigeons can not find a foothold on them. This is done e.g. with cement mortar or using sheet metal. Should not be carried out during the breeding season, where young can be found on springs / cornices / in nests. Few homeowners will sacrifice money on that solution.

– Tensioning of thin stainless steel wire or nylon cord a few centimeters above cornices or roof ridges. Unacceptable: These threads do not retain their elasticity and the threads become loose over time. The birds can therefore be injured or (if they panic) be held in the loose cords. A pest control company writes: "You have to calculate and calculate a bit of maintenance on the system, as the wire may break or become loose over time, and it may therefore be necessary to repair the system". However, due to their location, the wire systems are not maintained. Many homeowners are not aware that the system needs to be maintained and others will not pay for a lift to repair the system from time to time. It therefore poses a potential danger to all birds.

– Holes in the walls are masonry or provided with wire mesh, and other sites that the pigeons use from experience are shielded with wire mesh. Definitely not to be set up during the breeding season. Unfortunately, the nets do not hold, and holes in it mean that the pigeons can be caught UNDER the net and die a slow death. Sometimes they are stuck in the large-mesh net. Small birds can get through the net, but can not always find their way out again. Unacceptable.

– Pasta. Among the chemical pesticides, adhesive is an example. The intention is that the animal should feel uncomfortable landing on a soft substance. Adhesive paste hardens over time, so it loses its effect and must therefore be reapplied. If the paste is not made non-sticky with talc after application, then birds can stick. The paste is smeared in strips on cornices, gutters, roof ridges, signs and poles, which you do not want pigeons to sit on. It is argued by some companies that these bird pastes may not be purchased by private individuals and may only be used commercially by special companies. Still, one of the companies sells the pasta in its online store. Unacceptable: It has been seen that pastes have been used, which birds - especially small birds and young / weak individuals, who do not have as much strength - are stuck to.

- Lubricant: Other lubricants cause irritation of the pigeons' feet and legs and should deter the pigeons from landing. The birds will (allegedly) begin to avoid these places. A Danish company advertises that “the latest method of scaring the birds away consists of a paste that makes the birds believe that the house is on fire. This displaces swallows and pigeons to other areas ”. Sounds like a nice way to wrap up animal cruelty. In some places it is called Bird Gel. Unacceptable.

NEVER use polybutyl gel. Adhesive gel made from polybutene can harm any bird and any animal that comes in contact with it. These agents must not be used. The feathers of any bird that comes in contact with the concentrated, sticky gel are damaged and have all or part of the plumage destroyed, which destroys the water-repellent membrane of the animals' plumage and can destroy the feathers so much that the bird is prevented from flying. It is animal cruelty and a violation of the law. These gel agents are not selective as to WHO lands on them. Other birds are also likely to land on the gel, and smaller birds cannot get free, resulting in a slow death for the animal. According to foreign studies, it has also damaged larger birds such as barn owls and kestrel. Substances in the paste otherwise pull out into stone / concrete and discolor it and the gel is thereby harmful to the building.

– Shooting: Totally unacceptable and completely useless. Control companies, municipalities or others tell the customer that once the birds have been shot and killed, the problem will be stopped; however, the reverse is the case and the control companies know it. Any form of "regulation" of shooting has been shown by studies in major European cities to INCREASE pigeon herd size. Studies have also shown that the number of pigeons will increase to not only the number it was before the shooting, but to an even higher number. Therefore, the customer is sold a worthless and expensive "service", and the entire session must be repeated every 6-8 weeks. Since it is almost impossible to kill a bird the size of a pigeon with an ordinary air rifle and it often happens at a great distance, a majority of the birds that are shot are only injured. Due to the inaccessibility of sleeping and nesting sites, it is virtually impossible to find injured birds, and as a result, these birds are left to die a long and painful death. It is a clear violation of the Animal Welfare Act.

Wounded birds will seek shelter on other, nearby properties - e.g. on a cornice, a notch in a building facade, in a roof space or the like and this will have unpleasant consequences for the properties in question, as rotting, dead birds will lie in hard-to-reach places. Not to mention the aforementioned offense it is to let an injured animal die slowly from gunshot wounds. Foreign studies reveal that it is not uncommon for property owners to find dead and dying pigeons in various places on their property several days after the shooting.

– Laser light is used in some places against birds, but is considered "better" for birds other than pigeons. Laser light is definitely not safe to use where people and other animals move, not least because of the risk of eye damage. As far as is known not allowed in cities. Unacceptable.

- On balconies it is often used to tighten nylon fishing line back and forth in front of the opening or hanging net. Unacceptable: the animals are at high risk of being entangled in the lines (which are soft and yielding), get caught in the net or get caught behind it (small birds that can get through the meshes).

- By trapping set up special traps or decoys. This is done by certain pest control companies, but private people sometimes try too, settling down without control and knowledge to self-appointed bird catchers and killers. Unacceptable: people may forget to look after the traps, which can stand on a roof in strong heat / sun or in precipitation and wind for (maybe) days. Moreover, it is left to the ignorant to kill the animals. Finally, the method unacceptable, because it is deeply frustrating for a wild animal to be locked inside and even more frustrating if it cannot get back to their eggs (and live chicks). The pigeons will keep flying towards the nets of the trap, to get out. In terms of animal welfare, it is COMPLETELY unacceptable and illegal. Incidentally, a number of large studies have proven that capturing birds - even on a large scale - does not help to reduce the population at all - on the contrary.

Capture pigeons at night while they sleep. Unacceptable, for the same reasons as previously stated: chicks and eggs in the nest, and often very harsh (animal welfare completely unacceptable) and ineffective killing methods.

– Live rails has in recent years become more widespread in DK. In addition, live wires, which are put around statues and the like Unacceptable.

– Establishment of birds of prey nests in the city. At the moment it is a bit 'smart' to suggest it. Unacceptable: it involves one long animal abuse, many people will find it very unpleasant and shocking to see birds of prey killing pigeons become commonplace, and studies from other countries show that it has absolutely no effect.

– To rent a falconer to visit places in the city where pigeons live. Totally unacceptable: contains the same objection as before, is moreover an extremely costly affair, and the slain pigeons may have chicks at home in the nest. The method has been tried on Trafalgar Square in London - The London Evening Standard wrote on 21 September 2009: “The cost of flying a hawk to scare pigeons away from Trafalgar Square has soared to almost £ 60,000 a year. The bird of prey is flown daily for up to four hours as part of efforts introduced by former mayor Ken Livingstone to disperse birds he dubbed 'flying rats'. Since the scheme started in July 2003, a total of £ 354,829 has been spent on hawks and 130 pigeons have been killed. This equates to £ 2,729 spent per dead bird. Figures released to the Standard show that in the last financial year the scheme cost £ 59,020. ”. The Guardian wrote: "should the hawks keep flying - or is it time Londoners learned to peacefully coexist with pigeons?" Several newspapers called it "blood sport on Trafalgar Square".
