Tracked delivery anywhere in the United States. Free on orders of $75 or more; below that the only method offered is Express Delivery at $22, which is also available above the threshold as a paid upgrade. Allow 5 to 7 days, after a 24 to 48 hour handling time.

We give you 15 days from purchase to return an unused item. That is our own policy rather than a United States statutory right, because federal law gives no cooling-off period for an online purchase. Send it back unused and in resaleable condition and we refund what you paid for it, less a $29 per order handling charge; on a change of mind you also cover the return postage and the original delivery charge is not refunded. If the item arrives faulty, damaged or not as described, none of that applies: tell us and we put it right at our cost.

Your rights under federal and state consumer protection law are unaffected. That is a statutory right and nothing on this page limits it.

Looking after it

Look along the run once a year and after a hard winter. Leaf litter and nesting material packed between the points turn a barrier back into a ledge; clearing it restores it.

Pests need somewhere flat to land.

Hard moulded plastic, a moulded row of blunt points, sold per 20" strip. It closes the ledge rather than scaring anything off it.

Pests settle where there is a flat surface to stand on. This strip removes the surface, so the ledge stops being an option and they move on.

Hard moulded plastic, a moulded row of blunt points, supplied per 20" strip with no minimum order.

It fixes with silicone adhesive, screws, nails or cable ties, on masonry, metal, timber and most plastics, and the base flexes enough for a curved or irregular edge.

Typical places to fit it on this kind of job: fence tops, wall copings, gate posts and trellis rails.

Measure the whole edge rather than the messy part. A run with a gap in it moves the problem along rather than ending it.

Deterring pests is a question of surfaces rather than of scaring anything. A animal lands where it can stand, and it returns to that spot because it worked last time. Take the standing room away and the visit stops being worth making, which is why a physical strip outlasts every decoy, gel or noise device on the same ledge.

A fence top is a road. Cats, squirrels, raccoons and opossums all use it, and so do birds looking for a vantage point. Breaking the route on the fence solves several problems at once.

The strip itself is deliberately unremarkable: hard moulded plastic, a moulded row of blunt points, 20" strip. It fixes with silicone adhesive, screws, nails or cable ties, and the only part of the job that regularly goes wrong is the preparation. Adhesive on a dusty or damp ledge lets go in the first frost, so clean and dry the surface properly before anything else.

This page and the rest of the plastic range on this site sell the same physical strip under the pest people search for. That is worth saying plainly rather than implying otherwise: if you have pests and something else on the same building, you need more strips, not a different product. The stainless steel strip at /product/stainless-steel-spikes is the alternative material rather than a different design.

These strips deter rather than injure. Fitting them on your own boundary is straightforward; if the fence is shared, agree it with your neighbour first, which is a courtesy and often a rule.

Not sure yet? That is fine.

You can change your mind. We give you 15 days from purchase on any unused item. That is our own policy rather than a United States statutory right, because federal law gives no cooling-off period for an online purchase, and we would rather say so than imply a right you do not have. Send it back unused and in resaleable condition and we refund what you paid for it, less the $29 per order handling charge; on a change of mind you also cover the return postage.

If it turns up faulty, damaged or not as described, that is on us. Your rights under federal and state consumer protection law are unaffected. Read the detail on our refunds and returns page, or ask us anything before you order.

Frequently Asked Questions

Will this actually stop pests?

It removes the flat landing surface, which is what pests need. They move to the next available perch rather than fighting it. What it will not do is clear an established nest, so deal with that first.

Where do pests usually land on a building?

Most often fence tops, wall copings, gate posts and trellis rails. Walk the building and look for droppings or wear: the marks tell you where to fit before you measure anything.

Why are pests a problem worth spending money on?

A fence top is a road. Cats, squirrels, raccoons and opossums all use it, and so do birds looking for a vantage point. Breaking the route on the fence solves several problems at once.

Is this legal where I live?

These strips deter rather than injure. Fitting them on your own boundary is straightforward; if the fence is shared, agree it with your neighbour first, which is a courtesy and often a rule.

When is the best time to fit it?

Year round. Fence work is easier in dry weather because the adhesive needs a dry surface.

What is in the box?

One 20" strip, priced per strip. Order as many strips as your run needs; there is no minimum.

How long is a strip?

Twenty inches. Measure your run in inches, divide by twenty and round up.

What is it made of?

Hard moulded plastic.

How is it fixed down?

With silicone adhesive, screws, nails or cable ties. The surface has to be clean and dry before you start, which is the step people skip and then blame the adhesive for.

Do I need to drill?

Not necessarily. Adhesive holds well on clean masonry, metal and painted timber. Screws are the better answer on a surface that flexes or gets very hot.

Can I cut a strip down?

Yes. The base is designed to be cut between the pin positions so you can finish a short run without an overhang.

Will it fit a curved surface?

Yes. The base flexes enough for a gentle curve and for an irregular edge. A tight radius is easier with several short pieces than one long one.

How do I work out how many I need?

Measure the whole landing edge, not just the part with mess on it. Birds and animals move along to the first gap they find, so a run with a break in it moves the problem rather than solving it.

Does it hurt the animal?

No. The points are blunt and closely spaced so the surface simply cannot be stood on. Nothing here is designed to injure anything, and a product that injured an animal would be the wrong product as well as a legal problem.

Is it visible from the ground?

Barely, at height. Up close you can see it if you look for it. That is the trade for a physical barrier rather than something that relies on scaring an animal.

Will it stay put outdoors?

It is built for permanent outdoor use. The moulded plastic is UV stable and there is no metal to corrode.

Does it need maintenance?

Very little. Look along the run once a year and after a hard winter, because leaf litter and nesting material can build up between the points and turn a barrier back into a ledge. Clear it and it works again.

Should I use the stainless steel version instead?

They do the same job. The stainless steel strip is on /product/stainless-steel-spikes at $29 per strip. Moulded plastic is the lower cost option and is a sensible choice on a low fence or a run you can reach easily.

Can I use it on a gutter?

Yes, along the fascia or the outer lip. Clear the gutter first, and remember the whole edge needs covering rather than the part you can reach from the ladder.

Will it work on a fence top?

Yes, and the fence is often the right place to start because it is the route rather than the destination.

Can I fit it myself?

The fitting is simple. The height is the part to think about. If the run is on a roof edge or above a walkway, use a proper ladder or hire someone.

What tools do I need?

A tape measure, a cloth and a degreaser for the surface, snips if you are cutting a strip, and either a caulking gun for the adhesive or a drill and screws.

There is already a nest there. What now?

Stop and deal with the nest first, and if it is active leave it until the young have gone. In most cases that is also the law. Fit once the ledge is empty and cleaned.

How do I clean the ledge before fitting?

Wet the droppings down rather than sweeping them dry, wear gloves and a mask, bag the waste, then degrease the surface so the adhesive has something to hold.

Will it stop them landing somewhere else on my property?

No, and it is worth expecting that. Deterring one ledge moves the animal to the next one. Treat the whole run of edges rather than a single spot.

Can I combine it with the reflective tape or the gel?

Yes. The strip handles the ledge, the tape unsettles an open area like a garden or a yard, and the gel covers awkward narrow ledges where a strip will not sit.

What does delivery cost?

Free anywhere in the United States on orders over $75. Under that the store's Express Delivery is $22. Allow 5 to 7 days after a 24 to 48 hour handling time.

What if I change my mind?

You have 15 days from purchase to return an unused item. A $29 per order handling charge applies and the return postage is yours. That is this store's own policy, written out in full on the refunds and returns page.

Do you supply trade quantities?

Yes. The wholesale quote page takes the run length and the quantity and comes back with trade pricing.

Who do I ask if my question is not here?

Email theteam@pestspike.com with a photo of the ledge and a rough measurement. That is usually enough to answer it in one reply.

Fitting a strip against pests

4 min read Pest Spike Company

Find the edge before you buy anything

Walk the building and look for the marks rather than the animal. Droppings, wear polish on a lip, scratched paint on a rail: those tell you where the traffic actually is, and they are usually not where you first assumed.

Then measure the whole edge. Not the messy end of it. Pests move along to the first gap, so a half covered run relocates the problem by three feet and leaves you thinking the product failed.

Work out the quantity

Strips are 20" strip. Divide your measurement in inches by twenty and round up. There is no minimum order, so buy the run you measured rather than a pack size.

Clear the ledge first

If there is an active nest, stop. These strips deter rather than injure. Fitting them on your own boundary is straightforward; if the fence is shared, agree it with your neighbour first, which is a courtesy and often a rule.

Once it is empty, wet the droppings down before you touch them, wear gloves and a mask, and bag the waste. Then degrease. Adhesive on a dusty or damp surface lets go in the first hard frost, and that is the single most common reason a fitted strip comes down.

Fix it

Silicone adhesive, screws, nails or cable ties all work. Adhesive suits clean masonry, metal and painted timber; screws are better on anything that flexes or gets very hot. Cut between the pin positions to finish a short run rather than leaving an overhang.

Expect them to try next door's ledge

This is the part nobody mentions. Closing one edge sends the animal to the next one, so plan the whole set of edges on the building rather than the worst one. The strip on the gutter and nothing on the parapet is a job half done.

Check it once a year

Debris packs between the points over a couple of seasons and turns a barrier back into a flat surface. A look along the run each year, and after a hard winter, is all it needs.
