Hi guys! Does anyone know what’s going on with my dumb cane? I saw I gnat on it yesterday. Should I spray it with anything?

I wouldn’t spray it and I think it looks healthy. You probably saw a harmless fungus gnat. They are only annoying but not harmful to plants.

Thank you! What would you recommend spraying it with?

### Yolandaさんが2025-04-14にコメントしました

Neem oil I would just as a preventative so it doesn’t lay fungus eggs in your soil and have a team flying around

I tried neem oil on my desert rose and all the leaves fell off. Make sure to check dilution, mine was obviously too much.

ive never seen a dumb cane but if im being honest it kinda looks like a dieffenbachia

#### Sydneiさんが2025-04-14に返信しました

it’s the common name for the dieffenbachia. more recently people have been asked not to use it due to its historical origin

#### Yolandaさんが2025-04-14に返信しました

Dumb cane is the same name for a diffenbachia plant

#### KJMさんが2025-04-14に返信しました

They are the same thing.

I think you should get the yellow sticky traps to monitor any fungus gnat population. If the trap catches any, then treat your soil with a systemic pesticide or something for mosquitoes like mosquito dunks. Fungus gnats breed in the top inch or two of moist soil. Your dumb cane can handle a little dryness so make sure you're not overwatering.

Awesome, thank you!
