amazing fact about roaches.....once I lived in an apartment in a high rise in boston that had roaches....very annoying, beautiful apartments, parquet flooring very modern, and roaches...thank god I got to move out after breaking up with the guy. Anyway, they were gathered in the gas oven in the kitchen, and without thinking I sprayed bug spray right at the pilot light....well, a flame shot out past my head, Im lucky I didn't incinerate, would have made a great "RAID" commercial!
