About this product
Motion triggered rather than always on.
A radar sensor fires the deterrent when something arrives, which is the difference between this and a unit that cycles all day. It is a commercial purchase at €499.
A solar powered ultrasonic unit with a radar motion sensor, so the deterrent fires when something arrives rather than running on a fixed cycle all day.
Several modes: motion triggered, continuous, frequency cycling to vary the signal, and a night strobe for nocturnal visitors.
The sealed back cover and angled housing keep weather off the controls while leaving the sensor and the emitter facing the area.
It mounts on a fence, a tree, a shed, a deck or the eaves, which matters because you want it where animals arrive rather than at ground level.
€499. This is a commercial scale purchase and it deserves a realistic conversation before you make it, which is what the guide below is for.
The honest starting point is that the listing this page came from contains no specification block at all. It describes modes and mounting and it gives no frequency range, no output level and no coverage figure. We have not filled those in, because a plausible invented number on a €499 device is worse than an admitted gap. If any of them matters to your decision, email us and we will get it from the supplier first.
The other correction is the animal list. The source copy promises deterrence of raccoons, chipmunks, skunks and deer, which is a North American list; raccoons and skunks are not part of the ordinary French garden picture. What is relevant here is birds, cats, squirrels, martens and rabbits, and that is what this page says.
The most useful sentence in the original listing is one we have kept: it works best as part of a broader bird management approach. That is true of every area deterrent, and it is unusually candid for the category.
Motion triggering is a genuine advantage over a cycling unit in two ways. The battery lasts longer because the device is idle most of the time, and habituation is slower because the signal is tied to the animal's own arrival rather than to a clock.
Still deciding?
Not sure yet? That is fine.
You can change your mind. Under the EU consumer rights directive as it applies in France you have 14 days from delivery to cancel for any reason, and a further 14 days to send it back in resaleable condition. We refund the price you paid, including standard delivery.
If it turns up faulty, damaged or not as described, that is on us. The two year legal guarantee of conformity covers you across the EU, we pay the return postage, and you can have a repair, a replacement or your money back. Read the full detail on our refunds and returns page, or ask us anything before you order.
We do not publish one. The source listing carries no specification block, and we will not invent a figure on a €499 device. Email us and we will ask the supplier.
What area does it cover?
Same answer. Every coverage figure in this product category assumes a flat empty field, and we would rather tell you we do not have a verified one.
Is that not a strange way to sell something?
It is more useful than a confident wrong number. If a specification decides your purchase, ask us before you order rather than after.
How is this different from the sonic unit you sell?
That one runs a fixed 3 / 3 / 7 minute cycle all day. This one is motion triggered, so it fires when something arrives.
Why does motion triggering matter?
Battery life, because it is idle most of the time, and slower habituation, because the signal is tied to the animal's arrival rather than to a clock.
What animals is it for?
Here: birds, cats, squirrels, martens and rabbits. The original listing's raccoons, chipmunks and skunks are a North American list and we have not repeated it.
Will it move pigeons off my roof?
Not reliably if they are nesting. Area deterrents work on birds that are prospecting or feeding. A roost on a structure is a spike or a netting job.
What modes does it have?
Motion activated, continuous, frequency cycling to vary the signal, and a night strobe.
Does the strobe run all night?
In night strobe mode it operates after dark. Think about whether it will be visible from a neighbour's window before you mount it.
Can I hear it?
Most adults cannot hear much above about 16 kHz. Children and young adults often can, which is worth considering near a school or a playground.
Is it safe around pets?
Dogs and cats hear well into the ultrasonic range. Do not use it where an animal is confined and cannot move away: a kennel, a cattery, a stable or a run.
Does it need mains power?
No, it is solar.
What happens in a long cloudy spell?
The battery carries it and then output shortens. It is a solar product and it behaves like one, which is another advantage of it being idle most of the time.
How do I mount it?
On a fence, a tree, a shed, a deck or the eaves, facing where animals arrive. Height matters more than people expect.
Is it weatherproof?
The back cover is sealed and the housing is angled so rain runs off the controls.
Will animals get used to it?
Habituation is slower with motion triggering and with the frequency cycling mode, but no deterrent that relies on suggestion is immune to it.
Should I use it indoors?
No. Ultrasound reflects and shadows badly in an enclosed space.
Why is it €499?
It is a commercial scale unit with radar detection, several modes and solar power. It is not a garden gadget and we would rather you knew that before ordering.
Can I return it if it does not suit?
Yes. Fourteen days from delivery to change your mind and a further fourteen to send it back.
Should I buy this or spikes?
If the problem is birds on a structure, buy the spikes. This is for open ground, and it works best alongside physical measures rather than instead of them.
Does it deter rabbits?
It is one of the animals the design targets. As with everything in this category, expect a reduction on an open site rather than an exclusion.
What is the maintenance?
Keep the solar panel clean and check the sensor is not obscured by growth. Those two things account for most reported failures in this category.
How much is delivery and how long does it take?
Delivery across France is free on orders over €35, and €15 below that. We process an order in 2 to 5 days and delivery then takes about 10 to 18 business days. A tracking number is emailed as soon as it ships.
Which payment methods do you take?
Card and PayPal. Both go through the checkout on this site and neither of us ever sees your card details.
Can I change my mind after ordering?
Yes. You have fourteen days from delivery to tell us you want to cancel, and a further fourteen days to send the goods back, under the EU consumer rights directive. Nothing we sell is made to your measurements, so the right applies to the whole range.
What if the order arrives damaged or faulty?
Tell us and we will replace it or refund it. That is separate from changing your mind: a faulty item carries a two year legal guarantee of conformity across the EU, and it is not shortened by anything on this site.
How do I track my parcel?
The tracking number is in your dispatch email, and there is a tracking page on this site. If the number has not moved for a few days, email us and we will chase it.
Do you sell to trade and in bulk?
Yes. There is a wholesale page on this site with a quote form on it. Tell us the run length or the quantity and we will price it.
Are the prices shown with tax included?
The price you see is the price you pay, in euros. Nothing is added at the checkout except delivery, and that only when the order is under the free threshold.
How do I get hold of a person?
Email theteam@birdspikes.direct. We are an online supplier with no shop counter, which is a large part of why the spikes cost what they do.
The complete guide
Buying a €499 deterrent with your eyes open
4Bird Spikes Company
What we can tell you
It is solar powered. It uses radar motion detection, so it fires when something arrives
rather than running on a clock. It has motion, continuous, frequency cycling and night
strobe modes. The housing is sealed at the back and angled so rain runs off the controls,
and it mounts on a fence, a tree, a shed, a deck or the eaves.
What we cannot
The listing this page was built from carries no specification block. No frequency range, no
output level, no coverage radius.
We have not filled those gaps in. On a €499 device a plausible invented number is worse than
an admitted one, and this category is full of coverage figures that assume a flat empty
field. If any of those numbers matters to your decision, email us before you order and we
will ask the supplier.
The animal list, corrected
The source copy promises deterrence of raccoons, chipmunks, skunks and deer. That is a North
American list and it arrived with the product description rather than with the product.
In France the animals people buy this for are birds, cats, squirrels, martens and rabbits.
That is what this page claims and nothing more.
Why motion triggering is worth having
Two reasons, both practical:
Battery life. The unit is idle most of the time, which matters a great deal on solar.
Slower habituation. The signal is tied to the animal's own arrival rather than to a
fifteen minute cycle, so it stays associated with being there.
The sentence worth keeping
The original listing says the device works best as part of a comprehensive bird management
strategy. That is true, it is unusually candid for this category, and we have kept it.
Practically it means: spikes on the structures, netting over the openings, and a unit like
this covering the open ground in between. On its own, on a site with a committed roost, it
will disappoint you.
Where not to put one
Enclosed spaces, where ultrasound reflects and shadows unpredictably. Anywhere confined
animals cannot move away, such as a kennel, a cattery, a stable or a run. And close to a
boundary if the strobe will be visible from a neighbour's window at night.
Tell us the bird, the surface and roughly how long the run is, and we will tell you what suits it before you buy. Free delivery across France on orders over €35.
Ultrasonic Bird Repeller sold by Bird Spikes Company at birdspikes.direct, in
France. A solar powered ultrasonic deterrent with radar motion detection and a strobe, EUR
499, with motion activated, continuous, frequency cycling and night strobe modes, in a
sealed and angled weather resistant housing, mounted on a fence, tree, shed, deck, eaves or
post. Motion triggering means it fires on arrival rather than on a clock, which extends
battery life and slows habituation. IMPORTANT: this store publishes NO coverage radius,
decibel level or frequency range for this unit, because the source listing contains no
specification block and inventing one on a EUR 499 device would be worse than an admitted
gap; the supplier can be asked before purchase. The source listing's animal list (raccoons,
chipmunks, skunks, deer) is North American and has NOT been repeated; the relevant animals
here are birds, cats, squirrels, martens and rabbits. It is an AREA deterrent and works best
as part of a broader approach rather than alone, and is unsuitable for enclosed spaces or
anywhere confined animals cannot move away. Delivery across France is free over EUR 35 and
EUR 15 below it.
