Spikes are for pigeons that roost on a ledge, and the five sets here cover sills, deep ledges, gutters and short runs. The S4U steel kit suits a couple of sills and a length of coping. Choose the Defender plastic strips for ledges up to 20 cm deep, or the half round kit if birds are using the gutter. If birds are already nesting, read the legal position before you fit anything.

For deep sills, parapets and copings: this is the only listing here that states a ledge depth, up to 20 cm.

Guttering is the one place a flat strip will not sit, because the surface is curved. This half round kit is made for that shape, listed at 150mm x 112mm x 1m in stainless steel. If birds are using the gutter and the sills, you need this and a flat strip.
Pros:
- Half round profile for gutters

The short one, for a single windowsill or a short balustrade rather than a long run. Three pieces cover 78 cm, with 304 grade stainless steel spikes on a steel base. It is the only listing here that gives a pin layout: six pins per group across both directions, each spike 100mm long by 76mm wide.
Pros:

- Six pins per group, both directions

Start with your situation
- They are nesting, not roosting. Spikes give no protection at all — West Lothian Council puts netting as the only answer where birds are nesting.
- Listed building or conservation area. Consent may be needed before you fix anything to the outside — Worcestershire Regulatory Services and Bath & NES Council. Ask the council first.
- Roosting on ordinary sills. A standard steel strip covers it — the 3 m twelve-strip kit.
- Sills deeper than a standard strip. One listing here states a ledge depth, up to 20 cm — the wide plastic strip.
- Gutters as well as sills. A flat base will not sit on a curve — the half round gutter kit.
- A single short sill or balustrade. The shortest run here is 78 cm — the three-piece steel set.
Are They Roosting, or Nesting?
It is the first question Bath & NES Council asks first, and West Lothian Council is blunt about why: “If they are nesting they will not provide any protection.” Its answer for a nest is netting. A bird on a sill in the evening and gone by morning is roosting; nest material building up in a corner is not.
The Legal Position on Nests
Section 1(1) of the Wildlife and Countryside Act 1981 makes it an offence to do the following intentionally: “(b) takes, damages or destroys the nest of any wild bird while that nest is in use or being built;” (legislation.gov.uk). Fixing spikes over a nest in use is capable of being that offence, so wait until the nest is finished with.
Consent is a separate question. Worcestershire Regulatory Services states that “In most cases Listed Building Consent or planning permission will be required.” Ask the council first.
Where Spikes Do Not Work
Bath & NES records that spikes “are generally ineffectual if placed around parapet walls or installed at low densities.” A thin row on a wide ledge leaves standing room beside it, and debris collects between the pins until the deterrent stops deterring — check them once a year. Nor do spikes reduce bird numbers: West Lothian Council records that new birds move into preferred sites quickly.
What Decides the Choice
1. Whether they are roosting
Covered above. It decides everything else.
2. Covering the whole ledge, not most of it
Defra’s review of non-lethal bird methods reports work finding that “restricting openings and ledges to a maximum width of 4cm” would prevent feral pigeons using them (Defra) — a figure about ledge width, not about spikes, but the right way to think about the gap you leave. The same review finds exclusion works in proportion to how completely birds are shut out. Measure the ledge’s depth as well as its length.
3. The fixing, chosen for the surface
On masonry the fixing matters more than the spike. Bath & NES warns that plain ferrous fixings corrode and cause stone decay, and that a flexible mastic beats a hard-setting adhesive. Stainless fixings and flexible sealant on brick and stone; adhesive alone on PVC and painted wood.
If Spikes Are Not the Answer
If they are nesting, use netting. That is West Lothian’s position, quoted above.
Do not buy an ultrasonic unit for pigeons. Defra’s review reports a trial of an ultrasonic device which found “it had no effect on feral pigeons Columba livia.” and notes that “most species of birds do not hear in the ultrasonic range (>20kHz)” (Defra).
On a new sill, consider the angle instead. The same review reports that “ensuring an incline of at least 25°” on smooth materials — rising to 35° on wood and 50° on concrete — would prevent feral pigeons perching. If you are rebuilding a sill anyway, a slope needs nothing bolted to it.
Installation
- Clear the ledge before you fix anything. The S4U listing is explicit about the order of work: “The spike should not be installed until the waste and debris is properly removed.” Adhesive will not bond to a fouled surface, and a strip bedded on debris lifts.
- Working at a first-floor sill is work at height. HSE guidance on ladders says you should only use one “where the ladder will be level and stable, and can be secured” (HSE). A sill you can only reach by stretching sideways off a ladder is a job for a professional, not a longer reach.
- If it is going to take a while, get off the ladder. HSE’s own guide is that “if your task would require staying up a leaning ladder or stepladder for more than 30 minutes at a time, it is recommended you use alternative equipment.” Cutting, cleaning and bedding a run of strips takes longer than people expect.
- Cover the full depth. Two rows side by side on anything wider than one strip — the low-density failure above.
- Butt the strips together. A gap is somewhere to stand.
- On stone, use stainless fixings and a flexible sealant — not a hard-setting adhesive, and not plain steel screws.
- Check the fixings for the product you actually bought. Two of the five listings here state a fixing method and three do not; the comparison table below says which. The Defender listing notes that “Glue, screws and cable ties not included.”
- Look at it from inside first. Spikes on a sill are visible from the room behind it, and on a front elevation they are visible from the street. That is an observation, not advice from a source — but it is the part people regret.
- Check after a gale. Adhesive-mounted strips can lift.
Warning
Never use pigeon netting that is loose or poorly maintained — sagging net can entangle birds, which is both an animal welfare concern and capable of being an offence under section 1 of the Wildlife and Countryside Act 1981.
