Windex killed ant, how?

Question

We have a serious ant problem in my house. One day I was cleaning some window with Windex and I happened to see an ant. I personally feel really horrible about killing ants, but I knew my mom would throw a hissy fit if I let it get away, so I sprayed it with some Windex. It writhed, and literally in a matter of seconds it was dead. How exactly did the windex kill it, and why so quickly? Just curious.

Answer 1

all the chemicals  

Answer 2

I think windex contains ammonia, and that would do the trick.

Answer 3

you go drink a cup of Windex.... lets see how long you last!

Answer 4

It has harsh chemicals, too harsh for the tiny ant to handle.

Windex also kills spiders.
