I found ~30 baby spiders scattered across my bathroom ceiling/venturing into the adjacent room after coming home from a weekend trip. I vacuumed those up and sprayed the 2 rooms with pesticide. I’m worried about what to do next because I haven’t found the nest anywhere and online pictures seem to imply there should be many more spiders.
My best guess is that they came from a vent on the ceiling, because they’ve all been on the ceiling so far and its been many months since I’ve used the HVAC. I think I might just wipe all of the vent covers down with the pesticide… How worried should I be? Is there anything else I could do to keep them from spreading into my home? My partner is against harsh chemicals so I’m trying to avoid dousing the entire home.
I have some friends who used to have a really shitty apartment, first floor and basement of a shitty rowhome that by all rights should probably have been condemned.
The basement was two rooms, a larger room with nothing much but an old claw foot bathtub (that appeared to be hooked up to a drain but had no faucet or any obvious pipes nearby where it could have ever had water running to it)
And the spider room. I shit you not this room was almost nothing but floor to ceiling spider webs. Being a bunch of broke college kids with little enough use for the basement in general, they decided that they weren’t going to do anything about it. They just placed a sheet of plywood in front of the doorway and let the spiders do their thing.
And the spiders, accepted and respected this arrangement. They lived there for several years and not once did they ever see a single spider in any other part of the apartment.
The centipedes were another story, they frequently ventured into other parts of the house. One of those friends still likes to go on about how you can reason with spiders but not with centipedes.
But, I can only assume due to the high spider and millipede population in this apartment, there was basically no other bugs to be found there. The house was in the sort of perpetual state of squalor that you’d expect from 3 guys living on their own for the first time. The pipes leaked, everything was drafty, there was often a thin coating of grime on nearly everything, they had mice and maybe the occasional rat, but there was not a single roach, beetle, or fly to be found.
