I've been finding these crawling around the downstairs of the house that I am renting. I'd like to let the owner know if in fact they are destructive. They are approximately 2cm in length. Any idea what they are?


On an related note, maybe it's because I've started looking for these worms but I'm amazed at the number of spiders that I'm finding. A co-worker from the Netherlands said that it is the time of year for them. Is this a Europe thing? In all the places that I've lived, I don't remember Autumn as being spider time.
