Autumn signs: The First Male Giant House Spider


As the weather turns cooler and wetter this month, giant house spiders, which can grow up to 12cm long, will emerge as they hunt for female partners. “Spiders don’t specifically want to enter your home; in fact they’d rather stay away as there’s less food and it’s too dry and clean [possibly…],” says Simon Garrett, head of learning at Bristol Zoological Society. “Most species of spider stay outside all the time and never come in houses. However, in autumn, mature male house spiders start to move around in search of mates. Although most remain outside, some will move into a house if there is an entry point for them [we have lots of those]. It is this need to mate that changes their behaviour, so it seems as though they suddenly come from nowhere at certain times.”
