My Hardwood Floors Have Bug Holes

The floor was installed for a good deal.

My hardwood floors have bug holes.

Small holes caused by woodworm are typically found below the floor s surface. I live in texas. If there are termites you will see holes in the food or the wood will seem layered with brown frass. If you have hardwood floors the infestation can t be seen even for some years.

I have seen what you described many times. Regardless of where an infestation has started evidence will eventually emerge in these places. Their damage to hardwood flooring happens when their larvae bore into the wood through surface cracks. First the adult beetle lays its eggs on the wood surface then the larva bores through.

Hardwood floor refinishing can help you get rid of those unsightly scratches and marks. So laminate starts to sag and blister. This how to refinish wood floors article will show you how to do just that. I just had my new hardwood floor installed.

Start your search around the floor s edges and under windows where adult beetles tend to fly towards light. I am now concerning that they may used lower grade of material. Termites may eat the backing of the laminate floors. These beetles grow to 1 2 to 1 inch long and only attack softwoods primarily pine.

But pay a close attention whether the joist is load bearing or not. These small beetles grow to about 1 8 inch long as adults. Larvae hatch enter the wood and feed excreting sawdust like waste called frass that is often visible on the floor. The holes are created when the adult beetle emerges from its underground womb and they can also cause a lot of damage from within the flooring too.

Now back to the floor. The insects emerge as adults through tiny round exit holes. If the floor is infected with bettles or termites when will i see them. New flooring is installed and finished and then months or even years later small holes develop.

If you see larger holes up to the size of a dime this could indicate you have old house borers. Most hardwood floors have been dried and aged but were part of a tree and then board at one time. Additionally old house borer exit holes are typically oval with ragged edges. But i do see some holes in the wood similar to pictures on the web for powderpost beetles.

But as long as the damage is shallow in the coating and not in the wood itself you can renew the hardwood floor by adding a new coat of polyurethane right over the old finish. These are emergence holes made by adult beetles leaving the wood. But afterwards floors be one weaker.
