TIL the sticky traps I put in my greenhouse off Route 9 in Jersey caught 23 fungus gnats in 4 days
I was losing seedlings left and right and couldn't figure out why, so I put yellow sticky traps near the soil line and the counts told me exactly where they were breeding. If you've had gnat swarms, what did you use that finally broke the cycle, neem drench or beneficial nematodes?
