There seems to be no end, they invade and conquer every part of my garage.
It's relentless. I'm concluding there is no fix for this, but last resort asking the OCUK community - anything that has worked?
I used to have loads in my garage, I still have a few, you'll never stop them coming in.
But if you remove the ones you do have, you will at least stop them laying eggs which hatch into hundreds of spiders. If you see any spider nest bags, vacuum them up. It should reduce the number over time.
I go round with my henry hoover once a year and vacuum all the corners and anywhere where there's webs.
