😂 ... that's just too cute! Me, I'd let him go since he won't do anything for fungus gnats and can probably find more food for himself elsewhere. If you've got fungus gnats, though, I DO have a solution! It's called Mosquito Bits and it's brilliant... just follow the instructions - soak the appropriate amount of them in water for 30 minutes, strain the granules and use the water for your regular watering/feeding... I had that problem and this was INSTANT relief.... If the problem is really, really bad, you should use this for 3 weeks but I guarantee you, you won't have fungus gnats - although they might come back later on...
