That was the basis of a recommendation to keep ants out of your house,
that I read a few years back. If you see a single ant, kill it and
leave the corpse. That was probably a scout ant. If it finds something
good, it will go back to the ant hill and there will be a steady line
of ants coming and going to get the food. But if it doesn't come back,
another scout will check. If this one finds a dead ant, it will report
back to the hill that your house is dangerous, and the ants will avoid
it.
