Ant nests would only be accidentally trampled on by larger creatures or destroyed by mischievous children who play with water or fire under extremely rare circumstances.
If Earth is considered an isolated ant nest, then human civilization is also in a probability-based safe house.
The safety probability is so high that the danger can be considered negligible.
But...
When an ant is attracted by the scent of honey, it crawls onto the dining table in the yard and appears on an angry child's dessert. As the child's gaze shifts from their iPad to the line of worker ants, the safety factor of the ant nest drops drastically, and the danger level surges.
Or, if we look at it from a random and coincidental perspective, the ants are just passing through the yard in a group when a curious child happens to see them.
The moment they are noticed, the ants' safety house shatters, replaced by absolute danger and no room for resistance.
