I use Black Knight II. Works great, hard to find though. If I didn't have access to this (local reptile store sells it) I'd definitely invest in a can of PAM just to keep handy. Or maybe I'd try that Walmart Equate stuff people are mentioning. Hopefully I won't have to use it again, and it just becomes a very expensive roach killer (hey, I live in S FL and it's summer - we get some roaches here!)
