Additionally old house borer exit holes are typically oval with ragged edges.
My hardwood floors have bug holes.
Regardless of where an infestation has started evidence will eventually emerge in these places.
These are emergence holes made by adult beetles leaving the wood.
Larvae hatch enter the wood and feed excreting sawdust like waste called frass that is often visible on the floor.
First the adult beetle lays its eggs on the wood surface then the larva bores through.
These small beetles grow to about 1 8 inch long as adults.
I just had my new hardwood floor installed.
But pay a close attention whether the joist is load bearing or not.
Most hardwood floors have been dried and aged but were part of a tree and then board at one time.
Small holes caused by woodworm are typically found below the floor s surface.
If the floor is infected with bettles or termites when will i see them.
Termites may eat the backing of the laminate floors.
So laminate starts to sag and blister.
If you see larger holes up to the size of a dime this could indicate you have old house borers.
Hardwood floor refinishing can help you get rid of those unsightly scratches and marks.
The floor was installed for a good deal.
But afterwards floors be one weaker.
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.
If there are termites you will see holes in the food or the wood will seem layered with brown frass.
This how to refinish wood floors article will show you how to do just that.
But i do see some holes in the wood similar to pictures on the web for powderpost beetles.
Floor tiles become loose if termites damage joists floor supports the floor may start sagging.
New flooring is installed and finished and then months or even years later small holes develop.
I have seen what you described many times.
These beetles grow to 1 2 to 1 inch long and only attack softwoods primarily pine.
Their damage to hardwood flooring happens when their larvae bore into the wood through surface cracks.
I am now concerning that they may used lower grade of material.
The insects emerge as adults through tiny round exit holes.
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.
The floor is red oak.
Start your search around the floor s edges and under windows where adult beetles tend to fly towards light.
Now back to the floor.
