Answer: The gnats are probably fungus gnats, which in small numbers are not harmful, only annoying. The symptoms you describe could be due to a watering problem. These plants can usually withstand some drying, so I have a feeling the problem is overwatering. This is exacerbated by the fact that you've repotted--there's even more soil to hold excess water. If the plant gets at least some direct sun each day, and isn't in a very dark spot the rest of the time, it should be OK--but pale new growth is often a sign of lack of light, so if there's a brighter spot, I'd move it there for now. Remember, the less light the plant gets, the less water it needs. Also, air conditioning reduces the need for water if the temp. is set low. Check the soil before watering. Allow it to get dry down to an inch or so, then water thoroughly, and wait until the top inch is dry again. This will also help control the gnats.
