A toxic substance, if it is incorrectly dosed does not decimate 100% of individuals, whether bacteria or flies. There are mutations and variations in genes. The few survivors of this substance, if they have the chance to procreate, will create generations of resistant to this substance. To reduce this possibility, the dosages must be precise, respected and the treatment short-lived and varied if there is recurrence.
Bacteria have an advantage horizontal gene transfer which allows them faster and interspecies mutations.

In short, resistance is easily eliminated by respecting the rules.
