Chemicals


Use chemicals only when everything else fails.  The use of ORGANICS is recommended on this show whenever possible.  Remember, we don’t have to kill every bug.  There are good and bad bugs.  Generally called beneficial insects, these are the ones that eat other bugs we find less desirable to have around or they perform some other part of the work load out in the garden.

In Florida we have good and bad insects.  This chart tells you the roll of each critter.
