  Abstract  
  Microbial (bio) insecticides are products based on living micro-organisms which are pathogenic to insects. These micro-organisms have a long history of study and are considered to have great potential as pest control agents.

Pests of the urban environment have been less studied but cockroaches, flies, termites and stored product insects have received recent attention. Selection of a micro-organism for development as a bioinsecticide is based on the following criteria, which are interlinked.
