Pros and Cons of Bird Control Methods


Birds are unsightly and present a very real health threat as they carry a range of diseases that can be passed on to humans. Disposing of the birds can be considered a very unethical solution, but don’t despair – there are various deterrents at your disposal.

Bird Netting


Bird netting is a very low tech solution that works best for preventing birds accessing areas of roofs and building nests. Netting is the most suitable option for covering large spaces, but it is important to bear in mind that the size of the gaps in netting are specific to only one type of bird, so this is only a solution for properties where only one pest is present.

Pros of Bird Netting

  • The nets are easily installed
  • Discreet
  • Long-lasting – resistant to the elements for at least 10 years.

Cons of Bird Netting

  • Expensive installation
  • Requires regular maintenance
  • Potential for birds to become trapped behind the netting if not installed or maintained properly.

Bird Spikes


Bird spikes may look dangerous and harmful to birds, but they are simply designed to stop birds attempting to land on a surface. Most birds realise the potential threat in front of them and avoid the surface. This method is great for urban areas with heavy infestations of birds such as pigeons and seagulls.

Pros of Bird Spikes

  • Easy installation
  • Long lifespan

Cons of Bird Spikes

  • Unattractive
  • The spikes can gather feathers and droppings which can be unhygienic.
  • Clever birds collect debris to drop over the spikes and form the basis of a nest. This is not ideal in a product designed to keep the birds away!

Anti-bird Wire


Bird wire is a discreet, almost invisible deterrent that prevents birds from landing on ledges. This method can be used as a replacement for spikes.

Pros of Anti-bird Wire

  • Aesthetically pleasing
  • A cost-effective

Cons of Anti-bird Wire

  • If the bird doesn’t see the wire and flies straight into it, it can severely hurt or even decapitate its legs
  • Birds with long legs can learn to step over the wire
  • If the ledge is wide enough, the birds can fit in against the wall, behind your deterrent.



This system works by issuing a small electric shock to the bird when it comes in to contact with the system. This does not physically harm the bird (Avishock is even approved and recommended by several animal rights groups!), but it does create a psychological barrier through negative association, that will prevent the bird from wanting to land on your property again.

Pros of Avishock

  • Aesthetically discreet
  • Suitable for both domestic and commercial properties
  • The system is designed to withstand all weather types
  • Long lasting

Cons of Avishock

  • Requires maintenance to ensure the system works long term

Bird-Repellent Gels


There are two types of repellent gels: those with active ingredients and those without.

Gels without active ingredients have a sticky consistency that birds dislike as it restricts their ability to move freely. This prevents the birds wanting to land there again.

Gels with active ingredients have the added feature of utilizing UV light to make the birds believe the building is on fire. Birds can see through the UV spectrum, so where humans would see an orange gel, birds would see a fire that would scare them away.

In addition to this, scents that are distasteful to birds can be added to act as negative stimuli and encourage the bird to go somewhere more suitable.

Pros of Bird-Repellent Gels

  • Discreet
  • Suitable for indoor and outdoor use
  • Cost-effective
  • Able to withstand extreme weather conditions

Cons of Bird-Repellent Gels

  • Relatively short longevity, looking to last 2 years onwards
