NEVER use Canola oil for anything--not even cooking!!
Canola oil is 99% of some ant killers. It's the Canola oil that actually kills the ants, not the other added ingredients. I actually put this to the test because I didn't believe it myself. I used straight Canola oil and sprayed it on ants. Killed them quick and wiped out a whole colony with it!!
Canola oil is made from 100% GMO.
