Q & A: Ants in Terrarium

Image from Wikipedia Commons, by Fir0002/Flagstaffotos

I've never had the misfortune to find ants in a terrarium - let alone an entire colony moving in!  Does anyone have any ideas for Natalie K.:
"I have a 2.5 gallon desert terrarium that sits on my window sill It has a screentop lid to keep the humidity low and allow an extra light to sit on top. Ants have moved in though and are nesting in the soil. I don't know how long they've been there but I just noticed them moving pupae in. I dumped a bunch of water in(there's a layer of marbles and moss to allow drainage) and that seems to have scattered them out for now. How do I get them out for good??? Short of dumping the entire thing and starting over?"
See the solution to the ants in a terrarium.


  1. I think a pesticide might be my only option. They're back to moving in, despite the downpour. Anyone know if a pesticide spray will be ok for my plants?

  2. I would keep it moist for the most part, ants don't like being "wet" so keep it moist and eventually it will discourage them from coming. But since its a "desert" you might not want that.

    Anything with Neem is good. Its safe for almost all plants even carnivorous plants and they're very sensitive, they keep any fungal, mold and some insects. Or you can set up some traps around your terrarium, it will poison the colony.
