Get rid of pesky intruders in your home, lawn, working space or what not. Upon being activated they seek and bite the enemy.

Besides biting you (if you happen to be the enemy), they insert a tiny grain of salt on the wound to drive you nuts, and buzz an aggravating song in your ear.

A remote control unit disables them or a proximity card tells them not to harm you, when you are nearby.

Military uses: Put them instead of a mine field. Nobody will want to go through. If you need to cross to enemy territory just press the remote.

Civilian uses: keep the cats off the counter. Or out of the flowers. Prevent teens from sitting on the bench just outside your bedroom window. But you can enjoy a nice stay there watching the sunset.

Is it always wet when it's sunny, or always dry when it's raining?

No; why do you ask?

If you supported them on pieces of seagrass or wheatstraw then you would have "artificial flees but natural stays"

I have this army of Old Testament heathens that needs to be defeated and was looking for a sign...

We have Alexa and elementary school kids. We are... familiar... with many irritating songs. We are thinking of hiring the kids out with some megaphones in Ukraine in order to torture Russian fighters.
