It is hard to understand the idea that people fall for this crap.
If you drown a fly, I can bring it back. Just lay it on a pile of salt, and in a few minutes it will start to move.
Now, how many out there will try that?
It does work and there is a scientific explanation for why.
Ahh hahaha. Could it be that someone is selling a new dietary supplement called poison ivy? Or maybe too much sunlight and bleach exposure.
I wouldn't bother trying to bring them back. Either I kill the flies or point on of the cats towards them.
