the tea is from worm bins in my kitchen. sometimes there are little flyers when i open the lid. could they be fungus gnats? can their larvae end up in the tea and then in my plants? wondering because i have had a bad infestation of both fungus gnats and root aphids this run. i let the tea sit in a gallon jug for at least a month before adding it to my watering res. how long can eggs/larvae/bugs live in a closed jug?
