I noticed a spider in my kitchen a few days ago. It looked a bit evil and was hanging in a hammock type web rather than a 'traditional web). It was a copper colour with angular legs, about 2cm in size.My husband and i left it alone as it was doing no harm. Last night I looked at my kitchen ceiling and saw about 50 spiderlings. They were the same colour as the big spider I'd seen. I removed them all with a feather duster and bashed them outside (I dont believe in killing them). Any idea what the spider is and where it may have gone now? Is that the end of the spiderlings?
