'''Insect juvenile hormone analogues - methoprene, pyriproxyfen'''

These work by blocking receptor sites for insect juvenile hormone. This stops the juvenile insect from continuing along it's natural form of devlopment and never reaching adult status.

'''Chitin Inhibitors - Cyromazine, dicyclanil, lufenuron'''

These likewise block insect development by preventing the insect access to chitin, one of the key components to an adult insect's exoskeleton.
