Does Bird Repellent Gel Work on Pigeons?

Yes, bird repellent gel can work well on pigeons on the ledges, sills, signs and cornices where they perch and roost. You get the best results by spacing the dishes to suit how the birds use the ledge, fitting them to a clean, dry surface, taking away nearby food and adding spikes or netting where pigeons nest in numbers. In a 2020 field study in Italy, Bird Free gel cleared feral pigeons from a treated night roost and significantly reduced their use of a treated day roost for at least a year, and in a 2014 study in a Swiss pigeon loft two other gels cut landings sharply. In the UK, EnviroGuard sells the dish gels Bird Free Fire Gel (£67.02 for 15 ready-made dishes) and Ornaway optical gel (from £41.25 for a tube and 15 dishes), and the clear sticky Bird Repellent Gel at £15.99 a tube.

What the research says

Only a handful of independent studies have tested repellent gels on pigeons, and each one found something useful about how to get the most from gel.

• Gagliardo and colleagues, 2020 (Italy). Published in the European Journal of Wildlife Research, this study tested Bird Free gel on free-living feral pigeons using buildings. The gel removed pigeons from a night roost completely, significantly reduced their use of a day roost for at least a year compared with an untreated site, and discouraged them from building nests on treated sites for at least three months.
• Stock and Haag-Wackernagel, 2014 (Switzerland). Published in the journal Animals, this study tested two unnamed gels on shelves in a church loft used by about 85 pigeons. Landings on the optical gel shelves fell from an average of 18.6 a day to about 1 a day, and approaches to the contact gel shelves fell from 23.3 a day to under 1 a day. Neither gel stopped every pigeon, the gels picked up dust, feathers and insects over a few weeks, and the authors raised a welfare concern that sticky gel can glue feathers. They concluded that physical barriers remain the most reliable option.
• The UK government review, 2020. The review of non-lethal bird management carried out for Defra by the National Wildlife Management Centre summarises both studies, describing the optical gel result as a 92% reduction in landings a day.

Read together, the evidence says gel can make a ledge much less attractive to pigeons, and that results vary from site to site. Gel does its best work as part of a plan that also removes food and proofs the places pigeons nest.

When bird gel works

• Perching and roosting ledges. Sills, parapets, cornices, signs, beams, roof lines and gutter edges where pigeons sit or roost, which is where the 2020 study recorded its strongest results.
• Surfaces that are awkward to spike. Ornate stonework, signs and angled or vertical surfaces. The Bird Free Fire Gel product page states it can go on vertical surfaces, pitched roofs and angled surfaces, and magnetic dishes suit steel.
• Where appearance matters. The Bird Free dishes are 8mm low profile, and the Ornaway product page notes that installed dishes are usually invisible from ground level. The sticky gel is clear.
• Before a problem takes hold. Ledges where pigeons have just started to loaf, or new buildings, need fewer dishes and respond more easily than a long established roost.

Where gel needs some help

• Active nests. All wild birds are protected, and it is an offence to take, damage or destroy a nest while it is in use or being built, so gel is not a way to move pigeons off an active nest. Wait until the nest is no longer in use.
• Heavy, established colonies. In the Swiss loft study some pigeons kept landing on treated shelves. Where pigeons are nesting in numbers, netting or spikes that physically stop them landing are the more dependable choice, with gel on the features those cannot reach.
• Dirty or wet surfaces. Gel laid over droppings or dust will not perform, and the sticky gel must not be applied in wet weather or below freezing.
• Near garden birds. The sticky gel’s product page says not to apply it where it may entangle small garden birds, on or near bird feeders, or on structures that support them.
• Nesting or feeding gulls. The Ornaway product page says not to use it for nesting, feeding or night roosting gulls; it is for gulls only at occasional roosting sites. For gulls, see our guide on how to keep seagulls away.
• Somewhere pigeons are fed. If someone is feeding pigeons nearby, they will keep coming back. The RSPCA advises that reducing the food available is the most humane way to deter pigeons.

How to get the best results from bird gel

1. Work out what the pigeons are doing

The spacing of the dishes depends on how hard the birds are using the ledge. The Bird Free and Ornaway product pages give 10 to 15cm between dishes for nesting and night roosting areas, 20 to 25cm for daytime loafing near a food source, and 30 to 50cm for new buildings and occasional roosting. The gap between dishes should never be wider than the bird’s wingspan.

2. Clean and dry the surface

Remove droppings, nesting material and debris before you start. Wear disposable gloves and dust protection, dampen droppings with a biocide or detergent solution to keep dust down, and let the surface dry fully. An avian disinfectant such as PX Ornikill, £105.00 for 5 litres, is made for the job.

3. Fit the gel as the product directs

Bird Free Fire Gel comes ready made in its dishes. Ornaway is dispensed into the dishes supplied with a cartridge gun after the dishes are glued down, and the sticky gel is laid in parallel beads 5 to 7cm apart using a caulking gun, £7.70. On steel or cast iron, use the magnetic dishes or dish magnets.

4. Take away the reason they come

Ask neighbours not to feed pigeons, clear food waste and keep bins closed. Gel works far better on a ledge that is no longer next to an easy meal.

5. Proof the places gel cannot reach

Use bird spikes on long plain ledges and bird netting where pigeons fly into a space such as a light well or loading bay. Many buildings use gel and spikes together.

6. Inspect and maintain it

The Bird Free product page recommends inspections twice a year to repair any worn areas. The sticky gel beads need topping up every 6 to 8 months.

Which bird repellent gel should you buy?

• For most pigeon problems on a building: a dish gel. Choose Bird Free Fire Gel if you want ready-made dishes, the magnetic version for metal, or Ornaway if you prefer to fill your own dishes or need the 6 pack for a larger job.
• For a long, simple ledge on a budget: the sticky Bird Repellent Gel, or bird spikes from £2.04 a metre.
• For gulls: Bird Free Fire Gel names lesser black-backed gulls, but where gulls nest or feed, use proofing.

A worked example

Pigeons are loafing during the day on a 3 metre sill above a café. At the 20 to 25cm spacing for daytime loafing near food, that is 12 to 15 dishes, so one pack covers it: £67.02 for Bird Free Fire Gel or £41.25 for an Ornaway single pack, plus a cartridge gun and silicone to glue the Ornaway dishes down. If they are roosting there at night, the 10 to 15cm spacing means 20 to 30 dishes, so allow two packs.

Bird gel and the law

All wild birds are protected, including feral pigeons. Under the Wildlife and Countryside Act 1981 it is an offence to intentionally kill, injure or take a wild bird, or to take, damage or destroy its nest while it is in use or being built. Preventing birds from landing, roosting or nesting is not a licensable activity, provided the method does not injure them or trap them. A nest that is already in use is protected whatever method you were planning, so check for active nests first and plan the work outside the nesting season where you can. Our guide to bird control and the law sets out the position for England in 2026; the rules in Scotland and Wales differ.

Common questions

Does bird repellent gel harm pigeons?

The gels we sell are described on their product pages as non-toxic and designed to deter rather than harm. The 2014 Swiss study raised a welfare concern that very sticky gel can glue feathers. The dish gels are a cleaner format that is easier to remove, and the sticky gel’s product page says not to use it where small birds could become entangled or near bird feeders.

How long does bird repellent gel last?

Bird Free Fire Gel and Ornaway both state at least two years of protection when properly installed, with twice yearly inspections recommended for Bird Free. The clear sticky gel needs its beads replenishing every 6 to 8 months.

Will pigeons get used to bird gel?

The evidence differs. In the 2020 Italian study the effect at a day roost lasted at least a year, while in the 2014 Swiss loft study the time pigeons spent on treated shelves crept up slightly in the second part of the trial, although not by a statistically significant amount. Keeping the gel clean, removing food and proofing nest sites gives it the best chance.

How far apart should bird gel dishes be?

The product pages give 10 to 15cm for nesting and night roosting areas, 20 to 25cm for daytime loafing near food, and 30 to 50cm for new buildings and occasional roosting. On narrow ledges one row is usually enough; on wider surfaces keep the same spacing between rows as within them.

Does bird gel work on seagulls?

Bird Free Fire Gel names lesser black-backed gulls among the birds it deters, and Ornaway is for gulls only at occasional roosting sites, not where they nest, feed or roost at night. Where gulls are nesting on a roof, proofing such as gull spikes, post and wire or netting is the routine answer.

Is bird gel better than bird spikes?

It depends on the surface. Spikes cost less per metre on plain ledges, while gel suits cornices, signs and angled surfaces and needs no drilling. Our guide to bird gel vs bird spikes compares them side by side.
