As long as the women stayed calm, the spiders’ pulse rates were normal. However, when the women started screaming, over 90% of spiders showed signs of great anxiety. Some of them became so disoriented that they even moved towards the source of noise which only resulted in even more screaming from the women.
The panic in the eyes of this spider is clear to see |
The scientists now assume that evolutionary biology holds the key to understanding this irrational fear of screaming women. Although the source of noise itself does not expose the spiders to any real danger, for thousands of years, screaming women have attracted men to brutally kill the helpless arachnids with rolled-up newspapers or shoes.
Yet this excessively violent behaviour has been met with criticism. Leading arachnologists to advise the following measures when dealing with unwelcome common spiders:
1. Put a glass or a cup over the spider. Take care not to hurt its delicate legs.
2. Carefully slide a sheet of paper underneath the spider and the glass.
3. Carry the trapped spider into your garden or onto your balcony and let it go.
4. Squash the spider.
Point 4 is particularly important as scientists have also found out that four out of five spiders come back at night and cruelly take revenge on their attackers while they sleep.
