thought Steel wool was supposed to stop rats. I just went into a bathroom I am remodeling, and a rat had not only pushed through the steel wool plug I had in the toilet hole, but shredded the steel wool angrily over the bathroom. Or maybe it was joyfully. But the steel wool did not seem to bother him at all. It looked like an explosion of wool and toilet bowl wax.
This was 00 wool https://pestkill.org/mice/steel-wool/ ; maybe i need rougher stuff? If he pushes aside the stainless dog bowl and 25 pound weight then I'm moving.
