You dread the drop in temperatures when fall arrives. And for good reason… You generally notice countless spiders in your house or apartment. So much so that you no longer even dare to open the windows of your home in case these insects enter one of its rooms.

We often think that mowers discreetly enter our homes to to warm up when it's cold outside. But we actually have it all wrong. According to the experts interviewed by our colleagues, the latter would in reality be already with us for many weeks.
Indeed, spiders lay eggs in certain areas of our house, then y hibernent. “They therefore do not enter houses in the cold season to get warm. The spiders are already present with us, but they hide. »declares Christine Rollard, araneologist and teacher-researcher at the National Museum of Natural History (MNHN). And it is at the end of October that these insects come out of their hiding places.
Autumn is the time when spiders evolve considerably
Spiders rarely come into our homes to warm themselves when temperatures drop. They have already been living alongside us for several months. Only here, we do not notice them because they are still small. And then at the end of October, these reapers seem to appear out of nowhere on the walls or corners of our home.
Why then? ” It is the period when they are adultstherefore larger, more remarkable »explains, this time, Claire Jacquet, president of the French Arachnology Association (Asfra). Which means the spiders are more visible. The majority is a animal nocturne. We observe them much more after dark. Autumn is also the ideal time for spiders to breed.

Are the spiders we encounter in October dangerous for humans?
Many of us start screaming when we see a spider, no matter its size. Sometimes we no longer even dare to be in the room in which we observed this species. But we reassure you, according to professionals, the spider is not not captivated by human being.
The latter therefore does not squat in your home to stay face-to-face with you. “We are not not potential prey and they are not our predators. In summary: they do not calculate us. On the other hand, what makes them react is a change in environment. If something massive enough is felt by their sensory bristlesit will make them react – and generally flee. »explains Christine Rollard.
