Bird Deterrent Spikes

No. Spikes cause no harm to the animal - they make a surface uncomfortable to perch on rather than injuring anything that lands. Fit them securely and cover the full landing area, because spikes fitted loosely or with gaps can catch a bird rather than simply turning it away.

Install spikes on the exact places birds are landing or roosting, such as window sills, ledges, signs, beams, parapets and roof edges. Focus on flat perching points and leave no landing gaps between sections. Clean the area first so fixings adhere properly, and fit spikes securely according to the product instructions.

Spikes suit common nuisance birds such as pigeons and gulls, and other larger perching birds. Coverage and placement decide the outcome - if birds can find an uncovered section, they will keep landing on it. Measure your ledge or sill and choose enough spike length to cover the whole perching area.

Fitting method depends on the product and surface. Some spike systems use dedicated clips or fixings, while others may be installed using screws or a suitable outdoor adhesive where appropriate. Always follow the product instructions, check the surface is clean and dry, and make sure spikes are firmly secured and aligned to cover the full ledge.

Installed correctly and with suitable fixings, spikes are low-impact on surfaces. For delicate areas or places where you do not want permanent fixings, consider non-invasive options such as window clips where compatible. If using adhesive, choose one suitable for outdoor use and follow the curing guidance to avoid poor adhesion.

Almost always a coverage gap rather than a product problem. Walk the ledge and look for the section that was left short at one end, the gap where two runs meet, or the adjacent surface nobody spiked - a parapet, a sill above, a sign bracket. Birds move along a ledge to the first comfortable spot, so a run that stops short simply relocates them. Check too that the spikes have not been pushed flat or clogged with nesting material.

Bird spikes are generally legal as a deterrent, but they must be installed and used responsibly. Wild birds, their nests and eggs are protected in the UK, so avoid disturbing active nests and don't fit deterrents in a way that could trap or injure birds. Install spikes securely on appropriate surfaces and follow the product instructions for correct spacing and coverage. If you suspect an active nesting site or a protected species, seek advice before taking action.
