[Dimples]

The sooner you let them know the more seriously they’ll take your report and, assuming they’re a quality vendor, the sooner they can address the issue in their stock. If you wait a couple weeks they won’t be able to tell if the MBs originated with them or if it got infested after it arrived at your location. Someone will be at the greenhouse today (Thanksgiving). Even highly automated grow houses have someone around during the day. Email them and follow up with a call later if you need to.
