Curious. How do you circumvent the insect infestation issue?
Per OK guide:
Soak in Veggie Wash/liquid soap solution for 10 minutes.
Agitate and rub the blueberries in the water.
Place in a strainer or colander and wash thoroughly under a stream of running water.
Split open a few blueberries and check for white maggots.
If maggots are found the box should be discarded.
Other organizations have different variations, mostly based on soap wash. OU seems to be the most lenient IINM, only requiring wash under stream of running water.
Except for Pesach, in our kitchen any fresh produce that has a חשש of infestation gets washed or soaked with dish detergent as the first step.
