Morphology
The meaning is directly and compositionally derived from 'insect' (small arthropod) + 'powder' (fine dry material): a powder made from insects. This simple noun+noun compound follows transparent word-formation patterns found across languages, so a B1 learner who knows both constituents can reliably infer the MWE's meaning.
Etymology
Insect powder comes from the simple image of fine powder sprinkled where insects walk; people would dust cracks or paths so the powder touched and killed or drove away the bugs. So it means 'a powder used to kill insects'.
