Does anyone have suggestions for deterring spiders from casting webs
over the front of CCTV cameras?
The red glow of the infra red LEDs seem to attract them and the web
shows up very brightly.
Plus the spider keeps activating the inbuilt motion sensor.we
when it moves around.

Kleeneze do a spider repellent based on Horse Chestnut extract, but I can't
vouch for it's efficacy.

I had always thought this to be an old wives tale until my wife started
placing conkers around the place about five years ago, supposedly to deter
spiders.
I can say without doubt that it works but the conkers have to be renewed
annually. I don't have any scientific info on why it works or why we are
both arachnophobes.
OTOH I suppose a bunch of conkers hanging around a cctv camera.........would
look daft but could be worth trying.

From googling "cctv spider".

Youtube also has a few cctv spider videos.

I spray all around the camera with a surface flyspray that lasts a few
weeks.
I wish the lights were separate from the cameras. Then the camera
could be low and unseen by vandals, and the spiders could put their
webs over the lights if they want.

Why are the lights a dull red glow anyway? I have cheap cameras with
invisible lights. Why are they not all like that?

The RSC did their bit to try to find a scientific answer without coming
up with a firm conclusion. See
http://prospect.rsc.org/blogs/rsc/20...ed-of-conkers/.
(It includes a really good video which shows some schools at least still
encourage a proper approach to science).

WD40/other silicon spray prevents them from attaching webs...........

It's down to the different wavelength of the IR LEDs used and the
decreased sensitivity of the human eye to those at the higher end of
the IR spectrum. Wavelengths around 880nm exhibit the dull red glow
whereas those towards 940nm however do cost slightly more.

A slight correction: the visible LEDs are perhaps even lower at ~840nm
and, thinking about it, they are perhaps used also to match the IR
sensitivity of the camera being used.

I'd guess that the light attracts insects, which attract spiders. Maybe
try fly paper.

Visited a French chateau years ago and the tour included a visit to
the roof space. The guide stated the roof timbers were all made form
chestnut to keep spiders etc away. There was certainly a noticeable
absence of webs etc.

Insetcs really hate strong smells. Any of numerous strong smelling
oils can evaporate slowly enough to last ages. Paraffin is one fo teh
cheapest.

Using cheaper but visible LEDs simply means that the cameras cannot be
put in the best place or they will be vandalised. I removed the IR
filter from a camera but that altered the focus beyond any possible
adjustment.

That sounds very sensible.Will try that. Thanks.

Hmm, well I think my spiders are falling down on the job here, they
obviously do not eat the insects that haved turned my ankles into the
biggest itch I've ever known.

That what I thought until I twigged that the combination of amlodipine +
Cheese was in fact the culprit.

Either on their own, no rash, both together, massive bleeding scabby itches.

Was replaying a video of one making a web at night across my camera.
One slightly interesting thing - when it comes to making the fine
spiral part, the web does not show up under infrared instantly - it
takes about 30-90 seconds for the strand to become fully visible after
the spider has put it in position and moved further on.

Hahahaha thats the funnyest this ive heared in a long time...........Most web spinning spiders are blind,Bugs etc are attreacted to IR ,so spiders learn it as a food source..Oh and just to let you know ,Arachnology is my Job.

Nope, way of life for him.

This thread has been going since 2011, but it does seem to be a very popular
problem. all cameras should be fitted with an air blast device to clear the
spider webs away.

Having just cleared my porch area of webs and spiders nests I'm sure it
will take more than a blast of air to clean them away.

Not to mention reading what was actually written; I was explaining the difference of appearance to the *human* eye - not spiders.
