Crickets hopping around you say? Do you really mean crickets? They are big, you can catch them somehow.
I went through your grow and before reading about that I had seen white stuff on your plants leaves, which could be from aphids.
Do you see any flies around? Very tiny, flying around in circles?
Besides, nice grow, you seem to have very healthy plants. You had better not overwater them, but do not let them to dry.
