I had a few silverfish a while back, then spiderbro moved in and cleared that shit right up. he's been MIA the last week though, I really hope he's alright.
There's a couple of spiders around that I've left for this purpose, but their coverage sucks because they're passive, and serve as check points. I can't have too many of the check points around because they horrify female company. Already had to fire the one hanging around the front staircase for that reason.
Now, the centipedes have a FAR higher potential to terrify female company but they're a lot more reclusive and mobile compared to the spiders. It's like having seal team 6 vs. the TSA.
Plus the benefit of bravely protecting said female company and "handling" the centipede menace is not to be underestimated.
