name of drug for killing roaches in the US? guys i saw a large amount of roaches in my new home. i want to kill them but i don't want to use spray cuz it won't eliminate all of them. sprays are like guns, i need WMD (bio weapons). in China we have this drug (correct me if "drug" is not the right word), which is poisonous for roaches. i read roaches have the habit of eating the dead bodies of other roaches, so if one roach died of the poison, other roaches will die gradually by eating its body. all we need to do is putting the drug in some places they like to go. now i'm in the US, so i'm wondering if you know there is a similar drug here? i accept other recommendations you think are good choices. I hate roaches. THANKS!i'm in New York City if that helps.
