You may be sending the spiders in your house to their doom by putting them outside. The large, fast-running Tegenarias belong indoors, so (regardless of what I'm promising Mrs Steve I'll be doing with them) I quietly release them under the settee or fridge where they'll do good by scoffing the silverfish and other undesirables. Same goes for those daddy-long-legs spiders with the little bodies and impossibly tangly legs. They would just die outside in this weather. I just wish they wouldn't crap in the mugs on my mug tree, that's all! And the ones in the bath have fallen in, never entered via the plug hole, and flushing them down means certain death.
