If that sounds like your place, plastic bird spikes are the simplest fix there is, and this guide covers everything you need to buy the right amount and fit them properly the first time.\n\nWhy Plastic Bird Spikes Are the Best First Move\n\nWhen people search for the best bird deterrent for a home or shopfront, the answer is usually the least glamorous one. Spike strips work because they deal with the real problem. A bird does not care about your building, it cares about a flat, safe place to stand. Take that away and the bird leaves. No noise, no chemicals, no batteries, and nothing for the bird to get used to over time.\n\nHard plastic spikes in particular have a few things going for them. They cost less than stainless steel, they blend into the building far better, and they cannot rust or streak the paintwork. For anyone hunting the best plastic bird spikes for a house, a pergola or a fence line, an injection-moulded acrylic strip like this one is the standard choice.\n\nKnow Your Bird Before You Buy\n\nSpikes are at their best against pigeons, doves and gulls, the medium and large birds that perch and roost on edges. If you are searching for the best bird spikes for pigeons, you are in exactly the right place, since pigeons are the number one customer for this product worldwide.\n\nSmall birds are a different story. Sparrows and swallows can sometimes tuck themselves between spikes, so if your problem is tiny birds nesting in a corner, look at gels or netting instead. And while these strips are made for birds, plenty of buyers fit them as possum spikes for fences or to keep cats off railings and window ledges. The reviews on this product tell that story: swing sets, planter beds, balconies and pergolas, all cleared with the same strips.\n\nMeasuring Up: How Many Strips Do You Need?\n\nEach strip is 50 cm long and sold individually, so the maths is easy. Walk the property and note every spot where birds actually sit. Look for droppings, that is your map. Measure each run in metres, multiply by two to get the number of strips, then add about ten percent for cuts, corners and overlaps.\n\nCheck the depth of each ledge too. A single row protects a ledge up to roughly 10 cm deep. Wider ledges need two or even three parallel rows, because a pigeon will happily land in the calm zone behind a single front row. There is no minimum order, so a narrow sill might need just one strip while a shop awning takes twenty. You only pay for the length you need.\n\nWhere to Fit Them\n\nThe best bird spikes for ledges are the ones placed where birds actually land, which is not always where the mess ends up. Droppings fall, so look up from the stain to find the perch. The usual suspects:\n\nRooflines and ridge capping, parapet edges, window sills, fence tops, pergola beams, signage, security cameras, gutter edges and balcony rails. On solar panels, run spikes along the exposed edges to stop perching, and pair them with solar mesh if birds are getting into the gap underneath.\n\nInstalling Plastic Bird Spikes Step by Step\n\nFirst, clean the surface. Old droppings act like a welcome mat, telling birds this spot is home, so scrub the area and let it dry. Droppings can carry bacteria, so wear gloves and a mask for this part.\n\nThen fix the strips using whichever method suits the surface. A bead of outdoor silicone adhesive is the go-to for concrete, stone, metal and painted surfaces. Screws suit timber fences and beams. Cable ties are perfect for railings, pipes and camera mounts, and they are the renter-friendly option since they come off without a trace.\n\nWork along the run leaving no gaps. Birds are excellent at finding the one bare corner you left, so finish rows hard against walls and cut the last strip to length rather than leaving a space. The plastic base cuts cleanly with snips.\n\nPlastic or Stainless Steel?\n\nBoth do the same job the same way, so the choice comes down to the site. Hard plastic is the best bird spike option for most homes: cheaper, subtler, paintable, and completely rustproof, which matters near the coast. Stainless steel earns its keep on harsh commercial sites, wide gull-heavy rooftops and anywhere the strips will take a physical beating. If you are unsure, start with plastic on the main perches and see how the birds respond. In most residential cases that is the end of the problem.\n\nKeeping Things Humane and Legal\n\nEvery product we sell deters by inconvenience, not injury, and these strips are no different. The spikes are uncomfortable to land on, not sharp enough to wound. One reviewer even chose them because they kept her cat off without hurting its paws.\n\nAustralian native birds are protected by law, so the rules are simple. Deter landing, never harm a bird, and leave an active nest alone until the chicks have fledged. Blocking an empty ledge is always fine, and it is the best time to act. Fit spikes after the birds leave and they will not move back in come spring.\n\nAftercare\n\nThere is not much to do once the strips are up. Brush off leaves and cobwebs occasionally so the spikes stay exposed, and wash with mild soapy water if droppings land on them during the changeover period. The plastic is UV-stable, so you will not be back up the ladder replacing brittle strips in two summers.\n\nThe Bottom Line\n\nMatch the product to the bird, measure every perch, add ten percent, and fit the strips with no gaps. Do that and hard plastic bird spikes are about as close to fit-and-forget as pest control gets.
