I use this hot pepper powder always, it also helps the plants grow from what I'm told, If you smoke cigarettes, you can also make a spray with a small amount of dish soap, and some tobacco. The nicotine is extremely toxic, and will kill the bugs if they come in contact with it. Break a bunch of cigarettes up and soak the tobacco in water overnight. Beware of the possibility of TMV (tobacco mosaic virus), unless you boil your solution for ~20 minutes (after adding the tobacco) to kill the virus. Let cool, add your few drops of detergent and voila. Strain it, spray it. - (mogie)
