Greetings, The larger spiders are some sort of house spider, possibly Tegenaria domestica based upon the color bands on its legs. The smaller one would be a wall spider. Wall spiders are the sort that hide in crevices, cracks, and corners, and trap smaller pests that cross their paths. Both use silk to trap food, and both are very common in human-occupied buildings. I tend to find them near windows and doors at my museum, and there is one wall spider in a baseboard crevice about six feet from my laptop at home right now as I type this. I do not know enough about spider behavior to know why those specific spiders would wander. The house spider abdomens are smaller than what can be seen in online image searches, so they might be male forms looking for mates.
