We clean a large school atrium. We've done this for the past 7 years when the school was build and clean this once a year.

The spider nests and spiders have been steadily getting worse each year. Last year they were unbelievable; this year they are even more.

Does anyone have experience with a chemical to spray them which won't kill us as well.

The atrium consists of large aluminum window frames and double glazed windows.

I hate asking this and try to respect animal life, but this is too much.

Thanks.

Hi Spruce


I'm not sure spraying a chemical around the windows is going to help you long term...

Unleas you're going to chase the spiders away from the surrounding area, I would have thought that even if you killed off the spiders in the atrium, others will take their place...
Seen as its cleaned once a year as well, is it not to be expected..?

If you've done it for a few years and its becoming a pig of a job, maybe a price rise to make the job worth it again?

I think smurf has a spider feather duster , I'm sure he'll sure the link with you soon. Possibly with a YouTube video link also 😂😂

Thanks Don. I didn't want to hear that tbh. 

I was hoping to reduce their numbers to more manageable amounts. It appears that our clean once a year is causing them the thrive.

Last year we were 'forced' to use a stiff brush to get rid of their nests before cleaning wfp which probably added an hour and a half to the job.
We've raised the price a little this year but I feel I need to be careful and not go overboard. Its hard work but we are happy with the costing.  We can also spread cleaning out over the holidays to suit us, but they like the entrance area to be done last so its clean for the new year.

Thanks for your reply.

I think I remember Smurf once saying that washing with hot water was his answer.

Yep, I like to tickle them into submission

Boiling water/steam works better as they can survive submersed in water

I thought Robert the Spruce got all his inspiration from a spider?

Regards removing spider webs, egg sacks etc the worst job that sticks in my mind was a lakeside property exterior clean.

All the properties on that gated lakeside community are infested with spiders so are apparently treated once a year. The  contractors just goes around spraying a pesticide on the outside of the properties but they don't remove any of the mess so muggins here had clear years of build up even live spiders too.

What a pita of a job that was spruce so am not that keen doing another one like that in a hurry I can tell you.

Pretty tough to get rid of spiders, one of natures great survivors, think you will waste more effort and possibly money trying to find a chemical cure as I have yet to hear of a decent one.  Sorry

[slap bash]

Ant chalk might be the thing to use, or take a look at any garden shop for a spay.

Spiders don't like chestnuts apparently.  Maybe you could super-glue a bunch of them all over the atrium; say one every few feet?

My Mrs plays ant music sometimes. Seems to clear the front room.

So unplug the jukebox..........

I tried conkers but I found I damaged the window when I tried to whack a spider. Especially when I'd soaked my conkers in vinegar (oo err).
I've always wondered where William the Conkerer got his shoe laces from.

Thanks guys.
The school had a class of musical instrument beginners in the atrium this week. It did our heads in but it didn't bother the spiders.

His mates that moved in to Hastings - The Normans.

I went to clean a wfp brush today and nearly pooped myself as was the biggest and nastiest looking spider on the bristles that I have seen for a long time.

Actually that's a mis-nomer.  King William's day job was helping people with chronic foot problems which made walking very difficult.  His real title was William the Corn- curer

Can we get back on topic please as the op doesn’t want to listen to all this drivel surely 

Mind most of us are old so we do tend to wander off topic  just a wee bit now and then.
