Well, in the winter, I put them in the basement. Plenty of bugs down there.
That's the perfect solution... Unless you have a basement in which your pipes freeze in the winter, it's warm enough. We seem to have bloodsuckers, er, mosquitoes year round down there (not saying that it's wet, but it's ... wet). Right now the frogs seem to be on vacation, so that leaves the bug catching totally up to the spiders.
Now, if only we could get some spiders that catch those pesky stinkbugs we got swarmed by last fall...
I can’t keep them inside because our whole small home is finished. I might consider putting a spider door in the attic cover, but that is in my bedroom. *shudder*
Outside it rarely goes above freezing dependably during the day until mid-April. In the summer I adopt a few of the best performing spiders, and take the rest outside.
Either way, I am not going to entertain the thought of spider-guilt. If that means I will be reincarnated as a spider, so be it.
