I bought a money tree from IKEA and it came with what I think are fungus gnats (the little flying gnats that hang on the top of the soil and fly when they are disturbed).
I've tried drying out the soil for two weeks and spraying organic essential oil pesticide on the soil every few days. Nothing has worked. The tree's leaves have taken on a faded or browning color and is losing what seems like a lot of leaves.
Is it time to buy stronger insecticide?
Oh, I also changed the soil and added the beads for drainage when I bought it.
