The German cockroach is very good at establishing an ecological niche in structures and is resilient in the face of many pest-control procedures. To be successful, control strategies need to be thorough, sustained, and methodical; survival of just a few eggs is quite adequate to regenerate a nearly exterminated pest population within a few generations, and recolonization from surrounding populations often is extremely fast, too.
Why is the German cockroach so hard to exterminate?
Where do they like to hide?
German cockroaches prefer confined areas, and they are small compared to other pest types, so they can hide within little gaps and crevices that are easy to overlook, thereby evading people and their eradication efforts.
A strain of German cockroaches has actually emerged that responds to glucose as distastefully bitter. They refuse to eat sweetened baits, which presents a barrier to their control, given that those baits are an economical and effective means of regulation.
