Do Diatoms kill ants? I can say without a doubt that it alters their behavior. Can you see the balls of ants in the video clip above from ant pile 4? This is how fire ants respond when stressed. It is most commonly documented when a very large number of ants form a ball that can stay afloat in flood waters. The observation of this ‘balling up’ behavior is evidence of Diatoms efficacy at disrupting the ants.
Do you need to disrupt a few ants?
Give Diatoms a try.
