A hole in a wall can have two negative effects. It can allow heat to escape, causing higher energy bills. A hole in a wall can also allow mice and other pests to enter the home freely. Holes can develop around gas or water lines coming into the home or they can appear by windows or in the attic. Wherever a hole occurs, it can be blocked by following a straightforward process that requires little expense.

Use spray-in-foam to fill in small holes around pipes that run through the wall. Stick the applicator straw into the hole and pull it out as you spray. Spray around the entire circumference of the hole and fill in the spaces.
Stuff steel wool into holes in cement walls in a basement. Pack the steel wool tightly into the hole from the inside and the outside. Mice and other pests will not chew through the steel wool, and it will provide some protection from the cold entering through the hole.
Square off a hole in drywall using a utility knife and measure it with a tape measure. Cut a piece of drywall two inches larger than the measurements. Flip over the drywall and carefully score the plaster two inches in from the edge all the way around. Keep scoring the plaster until it comes off, leaving the paper. Place the piece of drywall in the hole so the paper around the edges overlaps the wall around the hole.
Spread joint compound around the edges of the new piece of drywall and blend it over the paper. Smooth the joint compound to blend it in to the rest of the wall. Let the joint compound dry overnight.
Sand the area to remove ridges and high areas. Use a drywall sanding sponge to sand the area smooth. The repair can be painted or wallpapered to match the rest of the wall.
