They're ba-a-a-a-a-a-ck! We've been without these things since
November. They reappeared a couple weeks ago when we had a warm
spell, so I'm assuming that they're coming from the attic - probably
through the recessed lights above the whirlpool that they seem to
favor.

Silverfish love a moist environment. I knew that much so I googled
and this site has some interesting information. For one thing it says
to put the bait in the light fixture. I guess it would be easy enough to
get into there.
