We've had dozens - probably hundreds of them - all over the lower floors of the house for years. Not so many upstairs. They've thrived and kept our house clear of Evil Spiders, we're all happy.
They literally all just vanished in about a week, and already, three of us have started spotting Proper Spiders again. I absolutely bloody hate spiders, but love my cellar spiders.
Why have they just vanished? They've never done a seasonal disappearance before. All we've got is some cobwebs but no lovely cellar spiders!
