I recommend scouring your memory to figure out where you think they might have come from. If you were indoors, most likely there were eggs on the plants from the very start. They have to come from somewhere. They either came on the plants, from another plant (indoor houseplants, etc) or you carried them in from outside on your clothes and shoes. They don't live in homes without plants. Scrutinize every leaf of a clone and ask about the care habits of the grower/dispensary. When I got my clones the bud tender brought them out and showed them to me on the counter. Which is great, to be able to look at but it before purchase, but also makes me think he's taking these plants out of the room and exposing them to people who are coming in from outside from who knows where-- potentially other gardens that could have infestations. Now that you know what the damage and eggs look like you will know immediately if they're okay or not.
