Bird Spikes

Which bird spikes do I need?

Bird spikes are chosen by two things: the bird you need to stop, and the width of the surface it lands on. Pigeon spikes stand 110mm high and come in three widths. Gulls need the taller 165mm seagull spike, because a gull will stand on anything shorter. Starlings and sparrows slip between pigeon spikes, so they need a spike with much closer pins. Every figure below comes from the product pages, and prices include VAT as listed in the shop on 8 October 2026.

Bird spikes compared

If your ledge falls between two widths, call us free on 0800 0687279 and we will help you choose. For a ledge wider than the widest spike, fit two parallel rows rather than one wider spike.

Narrow, medium or wide pigeon spikes?

Measure the depth of the ledge from the wall to the front edge, then pick the spike whose range covers it. Narrow pigeon spikes are 95mm wide between the outer tips and protect ledges 60mm to 125mm wide. Medium spikes are 140mm across the tips for ledges 140mm to 165mm wide, and wide spikes are 180mm across for ledges 180mm to 205mm wide. All three stand 110mm high and are made from 304 grade stainless steel in 500mm strips, two to the metre.

Stainless steel or polycarbonate bird spikes?

Stainless steel is the trade default, particularly on exposed and coastal work. Our stainless steel pigeon and seagull spikes are 304 grade, with snap-off points in the base, and the narrow spike also has rivet holes so it can be screwed where adhesive is not suitable. The narrow stainless steel spike carries a 10 year materials warranty, and the medium, wide and seagull spikes a 1 year materials warranty.

The Defender 4 and Defender 8 polycarbonate spikes are clear, UV stabilised and non-conductive, which is why polycarbonate is used in the TV aerial kit. They come in 330mm strips, three to the metre, and snap by hand at the moulded markers. Their product page notes they are slightly more visible than stainless steel spikes, so on a prominent frontage stainless steel is usually the neater finish.

How many metres of bird spikes do I need?

Measure the length of every ledge you want to protect, add the lengths together and round up to the next whole metre, because spikes are sold by the metre. If a ledge needs two parallel rows, double the length for that ledge. Then allow for adhesive: Fix All Crystal adhesive, at £7.93 a tube, lays about 8 metres of bird spikes.

A worked example. Suppose pigeons are using five window sills, each 1.5 metres long and 150mm deep. That is 7.5 metres, so order 8 metres of medium stainless steel pigeon spikes at £2.94, which is £23.52, and one tube of Fix All Crystal at £7.93. Your materials cost is £31.45.

For larger jobs, the spike and glue bundles include one tube of adhesive for every 10 metres of spike. The narrow pigeon spike and glue bundle is £129 for 50 metres, which works out at £2.58 a metre with the adhesive included. There are matching bundles for medium, wide and seagull spikes. Our bird spike cost guide works through more examples.

How to fit bird spikes

Most spikes are bonded with adhesive. Clean the surface first so the adhesive grips, run a bead along the ledge, then press the strip down so the adhesive pushes up through the holes in the base and locks it in place. Butt the strips up to each other with no gaps and take the run right to the end of the ledge. Where you cannot use adhesive, the narrow stainless steel spike can be screwed through the rivet holes in its base.

Gutters, windows and pipes have their own fixings, so nothing needs drilling. Gutter clips hold spikes on the lip of a half round or ogee gutter with water still running underneath, window clips mean you can still open a window over a protected ledge, and 430mm cable ties hold spikes on a pipe, two to each 33cm strip. Our bird spike fitting guide takes you through each surface step by step.

Bird spikes and the law

All wild birds, including feral pigeons and gulls, are protected, and an active nest with eggs or young in it must not be disturbed. Fit spikes before birds start nesting, and if a nest is in use on the ledge, wait until it is empty before you proof it. Our guide to bird control and the law explains what you can and cannot do.

Bird spike questions

Do bird spikes work?

Yes, on the surfaces they are designed for. Bird spikes stop pigeons, gulls and other birds landing on a ledge, sill, parapet, ridge, gutter or sign, and when installed properly they can last for over twenty years. They work best on edges and linear surfaces. Where birds are using a whole area, such as a courtyard, loading bay or the space under a roof, bird netting is the system for that.

What are the best pigeon spikes?

The best pigeon spike is the one that matches the width of your ledge. The narrow stainless steel pigeon spike protects ledges 60mm to 125mm wide and costs £2.04 a metre, the medium covers 140mm to 165mm at £2.94, and the wide covers 180mm to 205mm at £3.54. All three are 110mm high and made from 304 grade stainless steel.

What size bird spikes do I need?

Measure the depth of the ledge and choose the spike whose range covers it: narrow for 60mm to 125mm, medium for 140mm to 165mm and wide for 180mm to 205mm. For gulls, choose the 165mm high seagull spike, which covers 185mm to 210mm. If the ledge is wider than that, fit two parallel rows.

Do pigeon spikes stop seagulls?

No. Gulls are larger and longer legged than pigeons and will stand on a 110mm pigeon spike, so use the 165mm seagull spikes on ledges and the triangular ridge spikes on ridge tiles. Our guide on how to keep seagulls away covers roofs, chimneys and ledges.

Can you fit bird spikes without drilling?

Yes. Most bird spikes are bonded with adhesive, so the surface is not drilled. On gutters, the clip-on gutter kits need no drilling and no glue, and on windows the clips can be glued to the frame.

Do bird spikes hurt birds?

No. Anti-bird spikes are a humane method of bird control. The spikes do not harm birds; they leave no room to land, so the birds move on to find somewhere else to perch or roost.

Do your bird spikes come with a warranty?

Yes. The narrow stainless steel pigeon spike carries a 10 year materials warranty, and the medium, wide and seagull spikes a 1 year materials warranty. Any warranty on the installation is given by the company that fits the spikes.
