This spider has taken residence in a corner of one of the rooms, I’m not bothered by them but the web is getting a bit too big… can I just remove part of it to keep the size in check without causing harm to the spider?
I don’t think it’s an issue to remove part of the web. I’ve got spiders outside that tend to keep blocking the entryway and I have to destroy parts that get in the way of the path. They’re usually back within a day or so.
For a more solid answer, the link below describes moving spiders entirely by relocating part of the web with the spider. I think trimming the web is going to be less stressful than that.
