See how they run

A recent recon on the foundation of my building revealed small rodents have been borrowing into the mortar. This happens every fall and it's tedious. My back yard jungle provides plenty of romantic getaways for the mice to honeymoon with exceptional shaded suites under the leaves of the monster hostas.

Now I'm running herds of creatures who carry their own ecosystem.

This year I cheated by using 'mortar' in a tube. As if.
Dish soap for coating the fingers. Small rocks get pushed in along with the gunk.
