Sealing small gaps yourself.
- Steel wool or copper mesh: pack it into small gaps first. - Check your work: daylight through a gap means it isn’t sealed. - Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put.
Cleaning up droppings safely.
- Air the room out for 30 minutes first. - Wash your gloved hands, then your hands. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves.
