I was using some canned air on a computer today and discovered something odd. It seems quite toxic to ants.
There is a small ant nest somewhere by my back porch which results in a handfull of tiny ants wandering around. As I was spraying out the computer fan I managed to release some air away from the computer with the can tilted down (if you haven’t played with canned air, this results in a very cold white mist). I noticed the ants stopped moving as the mist settled down on them. I played around a bit more and sure enough, it kills them dead in their tracks.
At first I thought I just froze them, but I’m not sure if this is the case. It takes very little amount of the mist to stop them. I managed to take a few out from a light spray about 1 meter away from the can. As a test, I lightly sprayed my hand and except for a few cold droplets, it wasn’t that cold.
I also found just lightly spraying them with the air with the can upright didn’t effect them. Only when I used the can upside down did it have any effect.
What’s the deal?
