Dry Ice Insecticide!
NOTICE: this process was performed without a live animal inside the aquarium. Dry Ice is -109.3º F. and may cause SEVERE cold burns. Dry Ice releases a large volume of carbon dioxide (CO2) as it evaporates, capable of overtaking your oxygen supply in a confined area.
I performed this process as a (technically) "organic" form of pest control. the high concentration of carbon dioxide released into the air would suffocate any oxygen breathing animal, but at the same time, supply my plants with only what they need to breathe.
The dry ice was wrapped in a towel on my kitchen counter, and chiseled with an icepick and hammer to make appropriate sizes to fit the cups that would keep the ice from actually touching the glass bottom or sides of my aquarium.
like my pretty brown water??
The cups were then set into the pool of water around the front of my aquarium, and I killed the circulation fans..
quickly the C02 fog started to rise.
Realizing that the fog wasn't rising to the top of my tank (almost 3 feet tall) I had to act fast to help fill this puppy up. so I broke off a huge piece of dry ice and set it in a tupperware atop the tank, tilted at an angle so the fog would fall into the terrarium...
eventually the fog began to settle. I realized there is no way to save the ice for later(and nothing fun to do with it but make more fog). so I decided to do one more round just across the bottom of the tank. concentrations had to be highest in the substrate as that is where most pests would be during daylight.
and that's all folks! a "natural" way to eliminate pests in the terrarium.
