True. We called some before, they do kill quite a fair bit, but they don't work that well.
Apart from the big black/brown ones, we do unfortunately have quite a fair bit of German cockroaches
(the smaller ones). The pest control told us to get some very strong baits(*), and we reduced the German cockroaches a lot.
(*) translates to the most expensive one on the market (not available from regular supermarket).
Speaking about insect baits, chemicals etc. Few years back, we had rats problem. (What do you expect? This is not beautiful Boston/picturesque Quincy.) After trying a few different rats poisons, we ended up with the most expensive one which works the best.
The moral of the story: (to Don's refusal to believe,) brand does matter! Prices also indicate the quality or effectiveness.
