I always think about the whole 'in the walls' thing when I see a single one of those little creeps. Anyway, long story short, this showed up, I sprayed it about somewhat as directed (nooks and crannies in my kitchen, etc), and a couple days later I walked into my living room to find the very same insectoid invader on his back and very much dead. I'm pretty sure if there were any other bad boys lurking about in my place, they're goners now. UPDATE: It's been a couple days since I posted this and I've found 2 more (much smaller) bad boys randomly in my kitchen, both very dead. This stuff is definitely the real deal. UPDATE 2: I haven't seen a single bad boy since the previous update. By now I'm usually seeing at least one popping up somewhere. I'm sure that since I'm writing this I'll see one within a few days, but it was a nice ride while it lasted. The main reason I came back was to say this stuff actually works on ants, too! The main ingredient kills a long list of bugs that I didn't even realize were listed on the label given it's mainly marketed as a roach killer. But I had a random ant infestation out of nowhere as soon as the weather turned warm. I followed them back to a crack in my windowsill. Gave two small concentrated sprays into the crack and within a day, no more ants anywhere in my apartment. So yeah, this stuff is awesome. Other things: had no smell at all, but the nozzle was pretty leaky as other reviewers have said, so be ready for that. I wore a dishwashing glove whenever I used it after I noticed this, problem solved. TLDR: Bug alive? Spray this around, then bug dead.
