Be aware that thrips larvae (and not just adult thrips) have been found inside the tubes of scallions. Thrips larvae are white and translucent – see example images below. Consumers are advised to use a lightbox to see inside the tubes in order to determine whether thrips are present.
Infestations have been found in celery as well. Example images are included below.
