You can choose filler that matches the color of your wood, or you can paint it yourself. Using a putty knife, you'll fill the hole with wood filler, making sure it's completely full. Be sure to read the manufacturer's instructions because dry times may vary.

It will usually take approximately 30 minutes to an hour for the filler to dry, assuming you are repairing a small hole. Larger holes may take longer. For faster drying times of large projects, fill the hole one section at a time, letting each section dry before adding more filler. 

Once dry, sand the area to make it even with your floor. Now it's time to paint/stain the area. Don't forget to let the stain dry completely, following the manufacturer's instructions, before adding a glossy finish. Also note that you cannot stain/paint on all brands/types of fillers; therefore, you should check the specs first.

2. Wood Putty

Wood putty is better suited for small holes and cracks rather than larger projects. Unlike wood fillers, putties will not harden. Therefore, you will not need to sand the area upon completion. Because putties do not bond to the surface, there is also no need to sand the floor before applying the product.

According to Terminix, powderpost beetles are one of the leading causes of small holes in hardwood floors. These small beetles lay eggs in dead wood. Many times, the lumber is subjected to the insects in the lumber yard before it is used to create hardwood floors. Once the eggs hatch, the growth stage is slow, so homeowners usually do not notice the emergence holes until much later. 

According to Texas A&M, it can take anywhere from two to five years for powderpost beetles to surface from indoor wood. While inside, they go through three cycles - egg, larva, and pupa - then emerge as adults, ready to mate. However, females do not generally lay eggs on finished surfaces. 

How Do You Fill Large Gaps in Hardwood Floors?

Large gaps in hardwood floors should be handled differently from small holes. While you can place wood filler into the gaps, it will not last very long, especially in high-traffic areas. Instead, find or cut a small section of wood, placing it in the gap. It is probably best to apply wood glue to hold it in place.

Next, administer the appropriate amount of filler, allowing it time to dry. Finally, sand the filler piece and add your choice of finish.

There are several key differences between wood putty and wood filler. First, wood putty does not harden or bond to the surface. It cannot be sanded and usually cannot be painted or stained and is not suitable for long-term solutions. You'll need to continue applying putty to the holes as it wears away.

Wood filler, however, contains wood particles and fibers along with an ingredient that bonds to the surface, producing a longer lasting result. It is both sandable and stainable; however, both putty and fillers are available in color-matching products.  

How Big of a Hole Can Wood Filler Fill?

As long as you have enough wood filler, you can fix any size hole. However, it will be more difficult if the hole goes all the way through the wood, since it tends to be somewhat runny. It is that quality, however, that makes it ideal for quickly filling large holes that do not go all the way through.

Despite the challenges, you can still use wood filler to repair holes with no bottom. You will need either some Gorilla Tape or a spare piece of wood. If using wood, cut it to size and adhere to the hole using wood glue. Once the glue has dried, fill the expanse like you would any other and apply stain once it has dried.
