How many spiders does the average house have?
It is difficult to accurately determine the number of spiders that may be present in an average house, as there are many variables at play and it can vary widely from one home to another. Some homes may have very few spiders, while others may have more. It is also worth noting that many species of spiders are not commonly found inside houses, so the number of spiders present inside a house may be lower than in other parts of a home's environment.
