Spiders in my basement: Are they co-existing or eating each other?
I read that indoor spiders have never lived outdoors and visa-versa, that The spiders in my basement are from generations of basement-dwellers before. Is this true?
Reason I ask is because I have every kind of spider (it seems) in my 700SF basement...big, small, shy, aggressive, jumpers, runners, long legged, short legged, black, brown, etc., etc., etc. I don't bother them and they don't bother me, I'm just wondering if it's true that their ancestors lived inside with the prior homeowner. I can generally find 5 or more at any given time down there, but I don't kill them unless they're particularly creepy or I spot anything that resembles an egg sack. Any thoughts? Are they co-existing or eating each other?
True enough! I am working on lowering the humidity, and it's getting better (so long as I remember to empty the bucket on the dehumidifier). It would be interesting to identify each species to see what they eat. Perhaps I could host little spider socials
