I bought it on super clearance from Lowe's or Home Depot in July. It looked pretty dried out and abused. I clipped away dead/yellow stems and misted the plant between waterings. I was so pleased when it bloomed two weeks ago :) I haven't moved the plant to a new location or changed the way I care for it. But today I saw that the entire thing had nearly collapsed -- leaves are very wilted. I gave it just a little water and saw the little wormy/larva things in the drip tray. Not sure if this plant is in a poor state because I missed a watering, the bugs or both. I'd love any ideas on how to treat. Thanks!

On the other hand, I don't think the larvae in the first post are from fungus gnats. Fungus gnat larvae are smaller, translucent, and they don't have legs.

Now, with my jade I did not have any issues with insects whatsoever, but when I sprayed all my other plants I went ahead and sprayed the jade, too, as a preventative measure - huge mistake and one that I will never repeat. I since do not spray any of my succulents with Indoor Pharm, though I do have to at least spray their soil to keep the gnats from burrowing into it. I like that this particular stuff is all natural, but I would prefer to find a more reliable solution to my problem.

Generally, the plant that we think needs water, can be allowed to another day, or two, or three before it actually needs watering.
This is one method of reducing the number of gnats.

Misting will also often reduce the numbers of pests that attack our houseplants. It can, for a time, do instead of watering. We might also take a look at how much light the plant needs and how the sunlight might be contributing to its needing water so much. The surface dries out, the roots though are well moisturized...and we water; thus increasing the amount of water sitting around the roots.
Sometimes, we don't water to drainage, we assume the plant doesn't really need it, so we water in dribs and drabs...hoping some of it reaches the depths.

Sometimes its not gnats, but pesky insects such as thrips or whiteflies which are barely visible to the naked eye.
For these definite methods of control is employed.

Anytime you see a pest or damage from what is believed to be a pest, its a good idea to isolate the plant from each other. Spider mites, for instance, spread like wildfire from one plant to its neighbor and if not caught early, can cause a lot of damage that maybe ends up killing the plant.

If you can see them, then use a hand vac, if you cant see them but suspect they're in the soil; do a leaching, immerse the plant totally in water letting the water saturate the plant fully, letting the bubbles stop before assuming the plant is wholly inundated.
Then as the bugs surface---they have to breathe---we scoop them out and treat the watering as a normal water period and let the plant fully drain.
The leaching method though is recommended to be done only once or twice a year, fully saturating the soil is not recommended to do as a way to control bugs.
