Natural insecticide has long been lauded by environmental groups as a safe alternative to synthetics.  They kill a variety of pests found in gardens, yards, and homes.  However, there are problems with natural insecticide. 

Although natural insecticide has been around longer, there is less information on the efficacy of it as opposed to synthetic insecticide.  The most information of all of them can be found on Bt and on oils.  One problem with Bt is that it is only effective against a limited variety of insects.  It makes a good natural insecticide for crops such as corn, but for some other crops, it is useless.  Another problem with Bt is that insects become resistant to it over time.
